Tim drove 4 hours at an average speed of 60 miles per hour. How many hours would it take Tim to drive the same distance at an average speed of 50 miles per hour?

Answer:

C(x) = 175√(x² + 360000) + 528000 - 100x

Step-by-step explanation:

See the attachment below (Line PR = 1mile)

C(x) = Cost of Distance across the river + Cost of Distance along the land

Calculating Distance Across the river:

In triangle OPQ,The distance across the river is represented by line y

Line y is the hypothenus of the triangle

Pythagoras theorem states that:

if one angle of a triangle is 90 degrees, then the square of the length of the hypotenuse - the side opposite the right angle - is equal to the sum of the squares of the lengths of the other two sides.

So,

y² = x² + 600²

y² = x² + 360000

y = √(x² + 360000)

If it costs $175 per foot across the river then It'll cost

175 * √(x² + 360000) to lay cables across the river.

Calculating Distance along the land

Distance along the land is represented by line QR

Line QR = Line PR - PQ.

Where PR = 1 Miles (1 mile = 5280 feet)

So, PR = 5280

Line PQ = x

So, QR = 5280 - x

If it costs $100 per foot along the land,then it'll cost

100 * (5280 - x) to lay cables along the land

= 528000 - 100x

C(x) = 175√(x² + 360000) + 528000 - 100x

Answer:A)54 farms

B) 16 farms

Step-by-step explanation:

Y(1200) = (1200-1400)/100 = -200/100

Y(1200) = -2

Y(1600) = 1600-1400)/100

Y(1600) = 200/100 = 2

P(1200-1600) = (2y<-2)

2 standard deviation from the range = 68%=0.68

80 farms × 0.68 = 54 .4 approximately 54

B) 24× 0.68= 16.32 approximately 16

By using the empirical rule, it is expected that around 54 farms among the sample of 80 farms, as well as approximately 71 of 104 farms (after addition of 24 farms) will have land and building values per acre between 1300 and 1500.

The question deals with the concept of mean, standard deviation, and the empirical rule, specifically in the context of data relating to the values of land and buildings per acre on various farms.

A. Using the empirical rule, we know that approximately 68% of the population of a bell-curve distribution lies within one standard deviation from the mean. In this case, the mean is 1400 and the standard deviation is 100. So, one standard deviation above and below the mean is between 1300 and 1500. Therefore, approximately 68% of the 80 farms, or roughly 54 farms, have land and building values per acre between 1300 and 1500.

B. If we add 24 more farms to the sample, the total number of farms will be 104. Applying the same empirical rule, we'd expect approximately 68% of these, roughly 71 farms, to have land and building values per acre between 1300 and 1500.

The composite shape's area is 61.12.

Step-by-step explanation:

Step 1; To calculate the value of the composite shapes area we first divide it into shapes whose areas we know. In this case, the composite shape consists of only a circle's half and a triangle attached below it. If we can sum the individual areas of the two shapes we should be able to determine the area of the unknown shape.

Step 2; The triangle has a base length of 8 as it is from (6, 10) to (14, 10) so 14 - 6 = 8 and the height is from (10,10) and (10,1) so the height is 10 -1 = 9. So the area of any given triangle is 0.5 times the product of its base length and height. So area of this triangle = 0.5 × 8 × 9 = 36. The circle is not an entire one but only half so we calculate the entire circle's area and then half it to find its area. The diameter is 8 as the circle's ends are at (6, 10) and (14, 10) and radius = 14 - 6 / 2 = 4. The area of any circle is π times the square of its radius. So area of this circle = π × r²/2= 3.14 × 4²/ 2 = 25.12.

Step 3; Now we calculate the given composite shapes area by summing the two areas i.e areas of the half-circle and the rectangle.

Area of the composite shape = 36 + 25.12 = 61.12.

Step-by-step explanation:

Given:

Number of basket picked by Harper = 3.5

Number of basket picked by cooper = [tex]4\frac{1}{4}[/tex]

We need to find the number of basket of apples picked by Harper and Cooper together.

Solution:

Now we can see that one number is in decimal form and other number is in mixed fraction form so we will convert both the number in simplest fraction form and then solve the same.

Number of basket picked by Harper = 3.5

Now if we divide 7 from from 2 we get the answer as 3.5 so we can say that;

3.5 can be rewritten as [tex]\frac{7}{2}[/tex]

Number of basket picked by Harper = [tex]\frac{7}{2}[/tex]

Number of basket picked by cooper = [tex]4\frac{1}{4}[/tex]

[tex]4\frac{1}{4}[/tex] can be rewritten as [tex]\frac{17}{4}[/tex]

Number of basket picked by cooper = [tex]\frac{17}{4}[/tex]

Answer:

standard deviation of the distribution = 6.325.

Step-by-step explanation:

i) standard deviation of the population σ = 20

ii) size of sample n = 10.

iii) standard deviation of the distribution = [tex]\frac{\sigma}{\sqrt{n}} = \frac{20}{\sqrt{10}} = \frac{20}{3.162} = 6.325[/tex]

Final answer:

To find the standard deviation of the distribution of means for a population with a standard deviation of 20 and sample size of 10, use the formula: Standard Deviation of the Distribution of Means = Population Standard Deviation / Square Root of Sample Size. By substituting the values, you get the standard deviation of 6.32.

Explanation:

The standard deviation of the distribution of means for a population with a standard deviation of 20 and sample size of 10 is calculated using the formula:

Standard Deviation of the Distribution of Means = Population Standard Deviation / Square Root of Sample Size

Substitute the values: 20 / √10 = 6.32. Therefore, the standard deviation of the distribution of means is 6.32 for this scenario.

Answer:

The answer is 2/5

Step-by-step explanation:

I found 2 points and did y2-y1/ x2-x1 and got 2/5. And then I tested it and it worked.

Answer: the slope is 2/5

Step-by-step explanation:

The formula for determining slope is expressed as

Slope = change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

Looking at the graph given,

y2 = 0

y1 = - 2

x2 = 5

x1 = 0

Slope = (0 - -2)/(0 - 0) = 2/5

Answer: she rented the car for 4 days.

Step-by-step explanation:

Let x represent the number of days for which Sonya rented the car.

She pays a fee of $50 for the rental plus $20 each day she had the car. This means that if she rents the car of x days, the total amount that she would pay is

20x + 50

Suppose she pays a total for $130, it means that the number of days for which she rented the car would be

20x + 50 = 130

Subtracting 50 from the left hand side and the right hand side of the equation, it becomes

20x + 50 - 50 = 130 - 50

20x = 80

x = 80/20 = 4

The formula for determining average is expressed as

Average = the total cost of the televisions/ the sum of the televisions

Total number of model A television that was sold is 21

Total cost of 21 televisions = 299 × 21 = $8671

Total number of model B television that was sold is 13

Total cost of 13 televisions = 549 × 13 = $7137

Total number of model C television that was sold is 6

Total cost of 6 televisions = 619 × 6 = $3714

Total number televisions sold is 21 + 13 + 6 = 40

Total cost of the televisions is 8671 + 7137 + 3714 = 19522

Therefore, the average price per TV Sold is

19522/40 = $488.05 per television

Answer: Coefficient of x²y² =5184

Step-by-step explanation:

Already, x12y24x12y24 = 82944x²y²

From the expansion above, we have that: 324*16x²y²= 5184x²y²

Since, 82944x²y²/5184x²y² = 16

∴ Coefficient = 5184

Answer:

The length of the garden is 33 feet and the width of the garden is 4 feet.                                        

Step-by-step explanation:

We are given the following in he question:

Perimeter of rectangular garden = 74 feet

Let l be the length of the garden and w be the width.

The length of the garden is 9 feet more than 6 times the width.

Thus, we can write

[tex]l = 9 + 6w\\\Rightarrow l-6w = 9[/tex]

Perimeter of rectangular garden =

[tex]2(l + w) = 74\\\Rightarrow l+w = 37[/tex]

Solving the two equation by elimination method, we get,

[tex]l-6w-(l+w) = 9 -37\\-7w = -28\\w = 4\\l = 9 + 6(4) = 33[/tex]

Thus, the length of the garden is 33 feet and the width of the garden is 4 feet.

Step-by-step explanation:

the ratio of pv against nrt is called compressibility Z and measures the deviation from an ideal gas behaviour . When Z is plotted against pressure for CH₄ for 0°C and 200°C the curves will differ because there are

- negative deviations ( Z decreases) due to intermolecular forces

- positive deviations (Z increases ) due to molecular size of gas particles

then

- at 0°C the negative deviations prevail  respect to positive deviations at lower pressures ( so Z drops below the horizontal line first ) and then Z increases when pressure increases since the effect of positive deviation is higher ( then Z increases)

- Nevertheless, at 200°C the effect of intermolecular forces is lower and thus the positive deviations always prevail ( thus you observe only Z increasing(

The 99% confidence interval would be given by (0.172;0.228)

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The population proportion have the following distribution

[tex]p \sim N(p,\sqrt{\frac{p(1-p)}{n}})[/tex]

Solution to the problem

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by [tex]\alpha=1-0.99=0.01[/tex] and [tex]\alpha/2 =0.005[/tex]. And the critical value would be given by:

[tex]z_{\alpha/2}=-2.58, z_{1-\alpha/2}=2.58[/tex]

The confidence interval for the mean is given by the following formula:  

[tex]\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]

If we replace the values given we got:

[tex]0.2 - 2.58\sqrt{\frac{0.2(1-0.2)}{1400}}=0.172[/tex]

[tex]0.2 + 2.58\sqrt{\frac{0.2(1-0.2)}{1400}}=0.228[/tex]

The 99% confidence interval would be given by (0.172;0.228)

The confidence interval for the proportion is CI = 0.20 ± 0.0275.

The formula for calculating the confidence interval for proportion is expressed as:

[tex]CI=p \pm z \cdot \sqrt{\frac{p(1-p)}{n} }[/tex]

where:

Substitute into the formula;

[tex]CI=0.20 \pm 2.576 \cdot \sqrt{\frac{0.2(1-0.2)}{1400} }\\CI=0.20 \pm 2.576 \cdot \sqrt{\frac{0.2(0.8)}{1400} }\\CI = 0.20 \pm 0.0275\\[/tex]

Hence the confidence interval for the proportion is CI = 0.20 ± 0.0275.

The density function of a real number selected randomly within the range [2,10] is 1/8, with the probability of an event being the difference between the two values divided by 8. The probabilities that X is greater than 5, lies between 5 and 7 and that the inequality X^2 - 12X + 35 > 0 always holds are 5/8, 1/4 and 1 respectively.

The subject of this question is probability, particularly continuous uniform distribution. (a) A real number X selected from a certain interval [2, 10] has a continuous uniform distribution. Hence, the density function f(x) = 1/(b-a) = 1/8 for 2 ≤ x ≤ 10 and0otherwise. The probability of an event E, where E is [a,b], is the integral of f(x) from a to b, which is (b-a)/(10-2).

(b) Probability that X > 5 is the integral of f(x) from 5 to 10, which is (10-5)/8 = 5/8. Probability that 5 < X < 7 is the integral from 5 to 7, which is (7-5)/8 = 1/4. Lastly, the inequality X^2 - 12X + 35 > 0 factors out to (X-5)^2 + 10 > 0 which is always true as square number is always non-negative, thus the probability is 1.

Answer: The length is 24 inches. The width is 7 inches.

Step-by-step explanation:

Let L represent the length of the rectangle.

Let W represent the width of the rectangle.

The length of the rectangle is to be 3 inches more than triple the width. This means that

L = 3W + 3

The diagonal of the rectangle divides it into two right angle triangles and the diagonal represents the hypotenuse. The length and width represents the opposite and adjacent side. Applying Pythagoras theorem,

Hypotenuse² = opposite side² + adjacent side²

Therefore,

25² = L² + W²

625 = L² + W² - - - - - - - - - -1

Substituting L = 3W into equation 1, it becomes

625 = (3W + 3)² + W²

625 = 9W² + 9W + 9W + 9 + W²

10W² + 18W - 625 + 9 = 0

10W² + 18W - 616 = 0

Dividing through by 2, it becomes

5W² + 9W - 308= 0

5W² + 44W - 35W - 308 = 0

W(5W + 44) - 7(5W + 44) = 0

W - 7 = 0 or 5W + 44 = 0

W = 7 or W = - 44/5

Since the width cannot be negative, then W = 7

L = 3W + 3 = 7 × 3 + 3

L = 24

To find the total number of possible license plates with two letters followed by five digits (with repetition allowed), multiply the number of options for each position: 26 letters and 10 digits result in 67,600,000 different license plates.

Explanation:

The question asks for the total number of license plates that can be produced when the first two symbols are letters from the alphabet and the following five symbols are digits from 0 to 9, with repetition allowed for both letters and digits. To find the number of possible license plates, we use the principle of counting, multiplying the number of choices for each position.

There are 26 possible letters for each of the first two positions (since there are 26 letters in the English alphabet) and 10 possible digits (0-9) for each of the last five positions.

Therefore, the total number of license plates that can be created is calculated as:26 * 26 * 10 * 10 * 10 * 10 * 10. This equals 67,600,000 possible license plates.

This calculation assumes that each symbol (letter or digit) can be repeated, meaning the same letter or digit can be used more than once in the license plate.

Answer: the small bottle holds 15 ounces while the large bottle holds 23 ounces.

Step-by-step explanation:

Let x represent the number of ounces that a small bottle holds.

Let y represent the number of ounces that a large bottle holds.

He drank 2 small bottles and 2 large bottles, for a total of 76 ounces. It means that

2x + 2y = 76 - - - - - - - - - - - - 1

The day before, he drank 4 small bottles and 1 large bottle, for a total of 83 ounces. This means that

4x + y = 83 - - - - - - - - - - - - -2

Multiplying equation 1 by 2 and equation 2 by 1, it becomes

4x + 4y = 152

4x + y = 83

Subtracting, it becomes

3y = 69

y = 69/3 = 23 ounces

Substituting y = 23 into equation 1, it becomes

2x + 2 × 23 = 76

2x + 46 = 76

2x = 76 - 46 = 30

Answer:

16 women per 1 000

Step-by-step explanation:

The data was likely to be obtained from a survey. The question states how the information was gathered - most probably from questionnaires.

c. A simple model will be 16 women per 1 000 women. Proportion has been taken into account here.

Let 63 correspond with those that are going to get cancer out of 3980. The women have 63/3980 chance of getting cancer.

For 1 000 women that will be 1000/3980 × (63) = 16

Therefore the probability of a person getting cancer is 16 per 1 000 Ans

e. Large samples are essential to ensure that the results are representative of the actual population. In addition, large samples reduce inherent errors from deviations. Furthermore, useless data can be discarded and the remaining data still represent the actual population size. Lastly, large amounts of data are easy to scale up and use to develop models.

The two populations compared in the study were women whose mothers took the drug DES during pregnancy and those whose mothers did not. The data in the study were obtained through an observational study. A descriptive statistic can be used to estimate the number of women with tissue abnormalities out of 1000 in the population of women whose mothers took the drug DES during pregnancy.

a. The two populations in the study were: 1) women whose mothers took the drug DES during pregnancy and 2) women whose mothers did not take the drug.

b. The data in this study were obtained through an observational study, specifically a cohort study. This means that the researchers observed and compared the outcomes between the two groups of women without directly manipulating any variables.

c. A descriptive statistic that could be used to estimate the number of women out of 1000 in the population of women whose mothers took the drug DES during pregnancy and developed tissue abnormalities is:

Number of women with tissue abnormalities in the sample: 63

Descriptive statistic: (63 / 3980) * 1000 = 15.83

Therefore, an estimate is that 15.83 out of 1000 women in this population have tissue abnormalities that might lead to cancer.

d. Since the study only reported that women whose mothers took the drug DES during pregnancy were twice as likely to develop tissue abnormalities, without providing an exact percentage, it is not possible to estimate the number of women without more specific information.

e. Medical studies often use a relatively large sample size, like 3980, to increase the reliability and representativeness of the findings. A larger sample size helps to reduce the chance of biased or random results and increases the generalizability of the findings to the larger population.

Answer:

= 20.83%

Step-by-step explanation:

5/24 * 100

= 20.83%

To find what percent of people did not like the movie when 5 out of every 24 people did not, we calculate 5/24 as a percentage which is approximately 20.83%, rounded to about 21% of the people.

To calculate the percentage of people who did not like the movie, we need to set up a proportion where the number of people who did not like the movie is to the total number of people. Given that 5 out of every 24 people did not like the movie, we can express this as a fraction: 5/24. To find the equivalent percentage, we set up a fraction with 100 as the denominator and cross-multiply:

5/24 = x/100

Now we cross-multiply and solve for x:

24x = 5imes 100

x = (5 imes 100) / 24

x = 500 / 24

x = 20.833...

This equates to approximately 20.83%, which can be rounded to about 21%. Therefore, about 21% of the people did not like the movie.

Papa Bear ate 1.2 liters more than Mama Bear.

Framing in equation form, we get:

[tex]x = 1.2 + 0.80x[/tex]

[tex]x-0.80x=1.2[/tex]

[tex]0.20x=1.2[/tex]

[tex]x=\frac{1.2}{0.20}=6\ liters[/tex]

So, Papa Bear ate 6 liters of porridge.

Mama Bear ate = 0.80 × 6 = 4.8 liters

Baby Bear ate = 4.8 liters.

So, total porridge = Papa Bear + Mama Bear + Baby Bear

Total porridge eaten = 6 + 4.8 + 4.8 = 15.6 liters

Step-by-step explanation:

For n cups, the height of the stack is ...

  4 + (1/4)(n -1)

For a height of 8 inches, we can find n from ...

  8 = 4 +(1/4)(n -1)

  4 = (1/4)(n -1) . . . . . . subtract 4

  16 = n -1 . . . . . . . . . .multiply by 4

This question can be solved by just imagining the object formed or practically trying it out.

Therefore the correct answer to this question is option 2 ie

a cylinder with a radius of 1 unit.

Hope this helps.

The figure created is a cone with a height of 2 units and a radius of 1 unit.

Notice that we have a triangle, so if we rotate it around the y-axis, we will get a cone.

Because the rotation is around the y-axis, the height of the cone will be equal to the side AB of the triangle, so the height of the cone is 2 units.

And the radius of the cone is equal to BC, then we can see that the radius measures 1 unit.

Then the figure created is a cone with a height of 2 units and a radius of 1 unit.

Answer: Lisa would need to serve 17 customers to attain the projected income.

Step-by-step explanation:

Their income on a certain day is projected to be $357.

This situation can be represented by the equation 21x + 17y = 357, where x is the number of Lisa's customers and y is the number of Daisy's customers.

On a day that Daisy is sick, the income from Daisy would be zero. For Lisa to attain the projected income of $357, the equation becomes

21x + 0 = 357

21x = 357

x = 357/21

x = 17
