Continuous compound is e^rate x time

The formula would be D. 1200e^0.04t

Answer:  OPTION D A = 1200.e(0.04)(t)

Step-by-step explanation:

If the interest is compounded continuously for t years at a rate of r per year, then the compounded amount is given by:

A = P. e rt

P =$1200, r = 4% , t = t years

A = 1200.e(0.04)(t)

The probability that both the woman and her husband fail to get the correct brand of paint is 4/9.

To determine the probability that both the woman and her husband fail to get the correct brand of paint, we need to consider the probability of each event happening independently. Since the woman selects two brands at random out of the three available, the probability of her not getting the correct brand is 2/3. Similarly, the husband also selects two brands at random out of the three, so his probability of not getting the correct brand is also 2/3. Since the events are independent, we can multiply the probabilities together to get the probability that both fail to get the correct brand. Therefore, the probability is (2/3) * (2/3) = 4/9.

The husband's selections are independent of his wife's selections because each brand he chooses is not influenced by the brands his wife chooses. Regardless of what she selects, he still has three brands to choose from and selects two at random. This means that his probability of not getting the correct brand is the same regardless of his wife's choices.

Answer:

Total cost of the survey = $450

Step-by-step explanation:

Given:

Cost for each person = $1

Liked thin crust = 200 people

Liked thick crust = 270 people

Both crust like = 70 people

50 people did not like either type of crust.

We need to find the total cost of the survey.

Solution:

Number of people who like thin crust or thick crust.

⇒ 200 + 270 - 70

⇒ 470 - 70

⇒ 400

So, 400 people likes thin crust OR thick crust.

And, also 50 peoples did not likes either thin crust OR thick crust.

So, we add 50 people who did not like any type of pizza.

⇒ 400 + 50

Therefore, total cost of the survey = $450

Answer: The density of the paper clips is 0.64 g/ml.

Step-by-step explanation:

Given : Volume of water = 10.0 mL

mass of water =  25.0 g

After 51 clips added to water , the total mass = 28 g

Total volume = 14.7

Mass of clips =  total mass - mass of water

= 28 g-25g = 3g

Volume of clips = Total volume- Volume of water

= 14.7- 10.0 = 4.7 ml

Density of paper clips =[tex]\dfrac{\text{Mass of paper clips}}{\text{Volume of paper clips}}[/tex]

Answer:

How Pythagoras theorem relates to Trigonometry ratios

For a right angled triangle ∆ABC,

Let a = hypothenus

b = opposite

c = adjacent

Sin²θ + Cos²θ = 1

Provided that a² + b² = c²

To prove this divide through by c²

Tongive

a²/c² + b²/c² = c²/c²

Sinθ = a/c , Cosθ = b/c

So, the above equation becomes

(Sinθ)² + (Cosθ)² = 1

Sin²θ + Cos²θ = 1

Coterminal Angles

Coterminal Angles are angles who share the same initial side and terminal sides.

Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.

Final answer:

The Pythagorean Theorem and trigonometric ratios are related through the relationships between the sides of a right triangle. The theorem helps to calculate the sides involved in defining the sine, cosine, and tangent functions. Coterminal angles share the same trigonometric values despite having different measurements.

Explanation:

The Pythagorean Theorem is intimately related to trigonometric ratios, as it provides the fundamental relationship between the sides of a right-angled triangle. In trigonometry, the ratios of these sides define sine, cosine, and tangent functions. The Pythagorean theorem states that a² + b² = c², where 'a' and 'b' are the lengths of the legs and 'c' is the length of the hypotenuse of a right triangle. For example, given an angle θ within the right triangle, the cosine of θ is the adjacent side over the hypotenuse (cos(θ) = a/c), which implicitly uses the Pythagorean relationship when solving for the hypotenuse 'c'.

It's also important to remember coterminal angles in trigonometry, which are angles that share the same terminal side. Coterminal angles can be found by adding or subtracting whole multiples of 360° (or 2π radians). Although coterminal angles are different in measure, they have the same sine, cosine, and tangent values because these trigonometric functions are based on the position of the terminal side, not the actual angle measurement. Hence, coterminal angles have identical trigonometric function values.

Answer:

C. The new tomatoes are more consistent in their weights than the old tomatoes.

Context:

Agricultural scientists are working on developing an improved variety of Roma tomatoes. Marketing research indicates that customers are likely to bypass Romas that weigh less than 70 grams. The current variety of Roma plants produces fruit that averages 74 grams, but 11% of the tomatoes are too small. It is reasonable to assume that a Normal model applies.

The question is asking to compare the consistency of weights in two types of tomatoes based on their standard deviation. Select the option that best fits the standard deviation calculated for each group.

In statistics, standard deviation is a measure of the amount of variation or dispersion in a set of values. A lower standard deviation means that the values tend to be close to the mean (average) value of the set, while a higher standard deviation implies that the values are spread out over a wider range. The question asks you to compare the consistency in weight between two types of tomatoes, determined by their standard deviations.

If the standard deviation of the old tomatoes' weight is lower than that of the new ones', option B ('The old tomatoes are more consistent in their weights than the new tomatoes') would be accurate. On the other hand, if the opposite is true, option C ('The new tomatoes are more consistent in their weights than the old tomatoes') would be correct. Option A would be right if the standard deviations are similar, indicating similar consistency, and option D would apply if along with the new tomato weights being more consistent, their weight distribution is left skewed.

Answer:

The number of small mowers are 19 and the large mowers are 11.

Step-by-step explanation:

Given:

A garden supply store sells two types of lawn mowers. Total sales of mowers for the year were $8379.70. The total number of mowers sold the 30. The small mower cost $249.99 and the large mower costs $329.99.

Now, to find the number of each type of mower sold.

Let the number of small mower be [tex]x.[/tex]

And the number of large mower be  [tex]y.[/tex]

So, total number of mowers are:

[tex]x+y=30[/tex]

[tex]x=30-y\ \ \ ....(1)[/tex]

Now, the total sales of mowers are:

[tex]249.99(x)+329.99(y)=8379.70[/tex]

Substituting the value of [tex]x[/tex] from equation (1) we get:

[tex]249.99(30-y)+329.99y=8379.70[/tex]

[tex]7499.7-249.99y+329.99y=8379.70[/tex]

[tex]7499.7+80y=8379.70[/tex]

Subtracting both sides by 7499.7 we get:

[tex]80y=880[/tex]

Dividing both sides by 80 we get:

[tex]y=11.[/tex]

The number of large mower = 11.

Now, to get the number of small mowers we substitute the value of [tex]y[/tex]  in equation ( 1 ):

[tex]x=30-y\\x=30-11\\x=19.[/tex]

The number of small mower = 19.

Therefore, the number of small mowers are 19 and the large mowers are 11.

Direct variation is constantly proportional (constant multiple)

Answer:

a) y = - 1/2 x

Step-by-step explanation:

The equation that represents a direct variation is y = -3x. So, correct option is B.

A direct variation is a relationship between two variables where one is a constant multiple of the other. In other words, as one variable increases or decreases, the other also increases or decreases in a consistent manner. The equation for direct variation is typically of the form y = kx, where k is the constant of variation.

Let's analyze each given equation:

y = 2/x - This equation does not represent a direct variation because y is not a constant multiple of x.

y = -3x - This equation does represent a direct variation because y is a constant multiple of x. Here, k (the constant of variation) is -3.

y = x² - 2x + 5 - This equation is a quadratic equation, not a direct variation, as it involves x raised to a power greater than 1.

y = √x - This equation does not represent a direct variation as y is not a constant multiple of x.

So, the equation that represents a direct variation is option 2) y = -3x. It has a direct relationship between y and x with a constant of variation of -3.

The distance from P to origin is approximately 40.82 units.                                  

Step-by-step explanation:

We are given the following in the data:

The point P(21,35)

We have to find the distance of point P from the origin.

Coordinates of origin: (0,0)

Distance formula:

[tex](x_1,y_1),(x_2,y_2)\\\\d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

Putting the values, we get,

[tex](21,35), (0,0)\\\\d = \sqrt{(0-21)^2 + (0-35)^2} = \sqrt{1666} = 7\sqrt{34} \approx 40.82\text{ units}[/tex]

The distance from P to origin is approximately 40.82 units.

P(A) =0.54

P(B)= 0.68

P'(A)= 1-0.54 = 0.46

P'(B)= 1- 0.68 = 0.32

The probability of neither of both event will occur:

= P'(A)×P'(B)

=0.46 × 0.32

=0.1472

9 bottles of soda and 10 juice bottles are purchased

Solution:

Given that,

Sugar contained by each soda bottle = 45 grams

Sugar contained by each juice bottle = 35 grams

Let,

x be the number of soda bottles

y be the number of juice bottles

Given that,

Ethan purchased a total of 19 bottles of juice

Therefore, we get,

x + y = 19 ---------- eqn 1

Ethan purchased a total of 19 bottles of juice and soda which collectively contain 755 grams of sugar

Therefore, we frame a equation as:

[tex]45 \times x + 35 \times y = 755[/tex]

45x + 35y = 755 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 19 - y --------- eqn 3

Substitute eqn 3 in eqn 2

45(19 - y) + 35y = 755

855 - 45y + 35y = 755

10y = 100

y = 10

Substitute y = 10 in eqn 3

x = 19 - 10

x = 9

Thus 9 bottles of soda and 10 juice bottles are purchased

Answer:

20days

Step-by-step explanation:

The daily progress is 4ft - 3ft = 1ft

20ft/1ft = 20days

The snail will take 20 days to get out of the well.

To find out how long it will take the snail to get out of the well, we need to determine how many days it takes for the snail to climb a distance of 20 feet. Each day, the snail climbs 4 feet but slips back 3 feet at night. So, the net distance the snail covers each day is 4 - 3 = 1 foot.

Dividing the total distance of 20 feet by the net distance covered each day (1 foot), we find that it will take the snail 20 days to get out of the well.

Hence, the snail will take 20 days to get out of the well.

Answer:

option A- The candidate each participant supports.

Step-by-step explanation: the question asks about the 'statistics in the experiment', meaning the major factor or say the most important data to be considered to achieve the desired aim/result of the experiment.

From the question, the aim/result of the Research poll was to get 'the PROPORTION of people supporting each presidential candidate in the fall election'. Note that to find 'PROPORTION',  you must first find the individual values and then compare them. That's what 'PROPORTION' is all about - comparing number of things or people.

So to achieve this, the most important data-'statistics' in this experiment is knowing the candidate each participant supports.

For example, if there are 5 presidential candidates: Mr A, B, C, D & E and after interviewing 2,010 adults, you find out that:

134 people supports Mr A;

268 people supports Mr B;

402 people supports Mr C;

536 people supports Mr D and

670 people supports Mr E.

Now because you know the candidate each participant supports, you can now derive the 'PROPORTION' of people supporting each candidate which is 134:268:402:536:670. NB: you have to always leave your answer in its lowest term, so the proprtion here is 1:2:3:4:5.
