To know if two lines are parallel we must get their slopes if the slopes are equal, the lines are parallel.

Data

A (2,2)

B (3,6)

C(0,5)

D(1,9)

Formula

slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

Process

1.- Calculate the slope of line 1

slope 1 = [tex]\frac{6 - 2}{3 - 2}[/tex]

slope 1 = [tex]\frac{4}{1}[/tex]

slope 1 = 4

2.- Calculate slope 2

slope 2 = [tex]\frac{9 - 5}{1 - 0}[/tex]

slope 2 = [tex]\frac{4}{1}[/tex]

slope 2 = 4

3.- Compare the slope

slope 1 = 4 and slope 2 = 4, both slope are equals, then the lines are parallel.

Olivia should cut off an additional 19/16 inches of string.

We have,

Total length to be cut off: 3 3/4 inches

Length already cut off: 2 9/16 inches

First, let's convert the mixed numbers to improper fractions:

3 3/4 = (4 x 3 + 3)/4 = 15/4

2 9/16 = (16 x 2 + 9)/16 = 41/16

Now, subtract the length already cut off from the total length to be cut off:

3 3/4 - 2 9/16

= 15/4 - 41/16

= (60 - 41)/16

= 19/16

Therefore,

Olivia should cut off an additional 19/16 inches of string.

Final answer:

3-day Simple Moving Averages are computed by taking the average of three consecutive closing prices. The process is repeated for each set of three days within the ten-day period, resulting in a smoothed series of averages.

Explanation:

The 3-day simple moving average (SMA) of a series of stock prices is calculated by taking the sum of three consecutive closing prices and dividing by three. For the input series 7.78, 7.90, 8.00, 7.97, 7.86, 7.67, 7.60, 7.65, 7.65, 7.70, we perform the following steps:

For days 1, 2, and 3, the SMA would be (7.78 + 7.90 + 8.00) / 3.

For days 2, 3, and 4, the SMA would be (7.90 + 8.00 + 7.97) / 3.

Continue this process until you calculate the SMA for the last three days in the series.

Here is how they are actually calculated:

Day 1-3: (7.78 + 7.90 + 8.00) / 3 = 7.8933

Day 2-4: (7.90 + 8.00 + 7.97) / 3 = 7.9567

Day 3-5: (8.00 + 7.97 + 7.86) / 3 = 7.9433

Day 4-6: (7.97 + 7.86 + 7.67) / 3 = 7.8333

Day 5-7: (7.86 + 7.67 + 7.60) / 3 = 7.7100

Day 6-8: (7.67 + 7.60 + 7.65) / 3 = 7.6400

Day 7-9: (7.60 + 7.65 + 7.65) / 3 = 7.6333

Day 8-10: (7.65 + 7.65 + 7.70) / 3 = 7.6667

These averages help show the trend by smoothing out fluctuations in the data.

Answer:

The information given is not enough to determine their ages explicitly, so, here their ages are given in terms of Anna's age, which is the best that could be determined.

Anna's age = x years

Robert's age = (x - 11) years

Sara's age = (x - 9) years

David's age = (x - 1) years

Step-by-step explanation:

Let Anna be x years old.

Anna's age = x

Because Anna is 11 years older than Robert, we can say Robert's age is Anna's age minus 11.

Robert = x - 11

But Robert is 2 years younger than Sara, we can say Sara's age is Robert's age plus 2

Sara = (x - 11) + 2

= x - 9

David is 8 years older than Sara, we can say David's age is Sara's age plus 8.

David = (x - 9) + 8

= x - 1

Answer:

( 1, 7.5 )

Step-by-step explanation:

First I found the midpoint of the G and H coordinates. Then I found the midpoint of that new coordinate and G.

The coordinate of point J is given by the section formula with ratio 1: 3 is (1, 7.5).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of line, etc.

Segment GH has endpoints at G(-2,9) and H(10,3). Point J lies on GH between G and H such that GJ: GH is 1: 3.

Let the coordinate of the J be (x, y).

We know that the section formula is given as

[tex]\rm (x, y) = ( \dfrac{m_1x_2 + m_2x_1}{m_1 + m_2}, \dfrac{m_1y_2 + m_2y_1}{m_1 + m_2})\\\\(x, y) = ( \dfrac{1*10+3(-2)}{1+3}, \dfrac{1*3+ 3*9}{1+3})\\\\(x, y) = ( \dfrac{4}{4}, \dfrac{30}{4})\\\\(x, y) = (1, 7.5)[/tex]

Answer:

a. 2.28%

b. 30.85%

c. 628.16

d. 474.67

Step-by-step explanation:

For a given value x, the related z-score is computed as z = (x-500)/100.

a. The z-score related to 700 is (700-500)/100 = 2, and P(Z > 2) = 0.0228 (2.28%)

b. The z-score related to 550 is (550-500)/100 = 0.5, and P(Z > 0.5) = 0.3085 (30.85%)

c. We are looking for a value b such that P(Z > b) = 0.1, i.e., b is the 90th quantile of the standard normal distribution, so, b = 1.281552. Therefore, P((X-500)/100 > 1.281552) = 0.1, equivalently  P(X > 500 + 100(1.281552)) = 0.1 and the minimun SAT score needed to be in the highest 10% of the population is 628.1552

d. We are looking for a value c such that P(Z > c) = 0.6, i.e., c is the 40th quantile of the standard normal distribution, so, c = -0.2533471. Therefore, P((X-500)/100 > -0.2533471) = 0.6, equivalently P(X > 500 + 100(-0.2533471)), and the minimun SAT score needed to be accepted is 474.6653

Using the normal distribution, it is found that:

a) 0.0228 = 2.28% of students have SAT scores greater than 700.

b) 0.3085 = 30.85% of students have SAT scores greater than 550.

c) The minimum SAT score needed to be in the highest 10% of the population is 628.

d) The minimum SAT score needed to be accepted is 475.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Item a:

This proportion is 1 subtracted by the p-value of Z when X = 700, thus:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{700 - 500}{100}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a p-value of 0.9772.

1 - 0.9772 = 0.0228.

0.0228 = 2.28% of students have SAT scores greater than 700.

Item b:

This proportion is 1 subtracted by the p-value of Z when X = 550, thus:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{550 - 500}{100}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a p-value of 0.6915.

1 - 0.6915 = 0.3085.

0.3085 = 30.85% of students have SAT scores greater than 550.

Item c:

This is the 100 - 10 = 90th percentile, which is X when Z has a p-value of 0.9, so X when Z = 1.28.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 500}{100}[/tex]

[tex]X - 500 = 1.28(100)[/tex]

[tex]X = 628[/tex]

The minimum SAT score needed to be in the highest 10% of the population is 628.

Item d:

This is the 100 - 60 = 40th percentile, which is X when Z has a p-value of 0.4, so X when Z = -0.25.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.25 = \frac{X - 500}{100}[/tex]

[tex]X - 500 = -0.25(100)[/tex]

[tex]X = 475[/tex]

The minimum SAT score needed to be accepted is 475.

Answer:

The bus left New York city at 5:10pm

Step-by-step explanation:

First, we need to calculate the total number of hours the bus used to travel from New York to Washington.

Total number of hours traveled

= 2 1/3hr + 1 3/4hr + 5/6hr

= 7/3+7/4+5/6

=28+21+10/12

=59/12

= 4 11/12hours

Converting 11/12hours to minutes we will have 11/12×60 = 55minutes

Therefore the bus traveled for 4hours 55minutes.

If the bus arrived in Washington at 10:05 pm and the bus left New York 4hours 55minutes ago, this means that the bus did left New York at (10.05-4.55)pm i.e 5:10pm

4hours past 10:05pm will be 6:05pm

55minutes past 6:05pm will be 5:10pm

This means that the bus left New York city at 5:10pm

Answer:

The z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Mean of time to finish a test = 60 minutes

Standard deviation of time to finish a test = 10 minutes

Time that a student finishes the test = 23 minutes

2. What is the z-score for the student?

z-score = (Time that a student finishes the test - Mean of time to finish a test)/Standard deviation of time to finish a test

Replacing with the real values:

z-score = (23 -60)/10 = -37/10 = -3.7

z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%

Answer:

Perimeter of the model is approximately 1 m.

Step-by-step explanation:

Given:

Scale factor = [tex]\frac{1}{32}[/tex]

Actual base length of the sailboat (b) = 8 m

Actual hypotenuse length of the sailboat (h) = 13 m

Using Pythagoras theorem, we can find the third side of the right angled sailboat. Let the third side be 'l' m. So,

[tex]h^2=b^2+l^2\\\\13^2=8^2+l^2\\\\l^2=169-64\\\\l=\sqrt{105}=10.25\ m[/tex]

Now, actual perimeter of the sailboat = Sum of all the 3 sides

Actual perimeter = 13 m + 8 m + 10.25 m = 31.25 m

Now, we know that,

Scale factor = Model dimensions ÷ Actual dimensions

So, in terms of perimeter,

Scale factor = Model perimeter ÷ Actual perimeter

[tex]\frac{1}{32}=\frac{Model\ perimeter}{31.25}\\\\Model\ perimeter=\frac{31.25}{32}=0.97\approx1\ m[/tex]

So, perimeter of the model is approximately 1 m.

Answer: standard deviation is 6.96

Step-by-step explanation:

Let m be mean

M=mean=sum/n

M=525/5

M=103

The standard deviation formula is :

S.D = sqrt( Summation of |x-m|^2 / n-1)

Let start finding:

|x-m|^2

For 1st: |119-103|^2=36

For 2nd: |104-103|^2=1

For 3rd: |92-103|^2=121

For 4th: |97-103|^2=36

For 5th: |103-103|^2=0

Summation of |x-m|^2 = 194

The standard deviation formula is :

S.D = sqrt( Summation of |x-m|^2 / n-1)

S.D= sqrt(194 / 4)

S.D=sqrt(48.5)

S.D= 6.96

The standard deviation is approximately 9.1 ounces.

Calculating the Population Standard Deviation

To find the standard deviation of the population of newborn babies' weights in a hospital, we need to follow several steps. The weights of the babies (in ounces) are 119, 104, 92, 97, and 103.

Calculate the mean (average) weight: (119 + 104 + 92 + 97 + 103) / 5 = 103

Determine the squared deviations from the mean for each weight: ((119 - 103)²), ((104 - 103)²), ((92 - 103)²), ((97 - 103)²), ((103 - 103)²).

Sum the squared deviations: 256 + 1 + 121 + 36 + 0 = 414.

Since we have the entire population, divide by the number of data points, which is 5: (414 / 5 = 82.8).

Take the square root of 82.8 to find the population standard deviation: √82.8} =approximately 9.1 ounces.

The population standard deviation of the babies' weights is approximately 9.1 ounces, rounded to two decimal places.

Step-by-step explanation:

Given:

-  Siding material cost = $18.50 per square yard

- installation cost = $12.40 per square yard

- width of one side = 22 ft

- height of one side = 10 ft

Find:

- How much should you charge to put siding on the ends of the house

Solution:

- Assuming the the cost of material is also borne by you. Summing the rate of material and installation for both sides for you per square yard:

Total rate for both side = 2*($18.50 per square yard + $12.40 per square yard

 Total rate for both side = $ 61.8 per square yard

- Area covered by a side is:

  Area covered = 10 * 22 = 220 ft^2 * (yard^2 / 9 ft^2) = 24.44 yard^2

- Total amount you will be charging is:

   Total amount = Total rate for both side * Area covered

   Total amount = $ 61.8 per square yard * 24.44 yard^2 = $1510.32

Answer: The maturity value is $43743

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount that was taken as loan.

R represents interest rate.

T represents the duration of the loan in years.

From the information given,

P = 42000

R = 8.3

T = 6 months = 6/12 = 0.5 years

I = (42000 × 8.3 × 0.5)/100 = $1743

The maturity value is the total amount paid after the duration of the loan. It becomes

42000 + 1743 = $43743

Answer:

The cost of 1 eraser is $0.07.

Step-by-step explanation:

Given:

The school store sells erasers. If Mrs. McBryde purchases 1000 erasers for $70.00,

Now, to find the cost of 1 eraser.

Let the cost of 1 eraser be [tex]x.[/tex]

The cost of 1000 erasers is $70.00.

So, 1000 is equivalent to $70.00.

Thus, 1 is equivalent to [tex]x.[/tex]

Now, to solve by using cross multiplication method:

[tex]\frac{1000}{70} =\frac{1}{x}[/tex]

By cross multiplying we get:

[tex]1000x=70[/tex]

Dividing both sides by 1000 we get:

[tex]x=\$0.07.[/tex]

Therefore, the cost of 1 eraser is $0.07.

Final answer:

The cost of one eraser is found by dividing the total cost of $70.00 by the number of erasers purchased, which is 1000, resulting in a cost of $0.07 per eraser.

Explanation:

To find the cost of one eraser, we divide the total cost by the number of erasers Mrs. McBryde purchased. She bought 1000 erasers for $70.00. So, we need to perform the division $70.00 ÷ 1000 erasers = $0.07 per eraser. This means each eraser costs 7 cents.

E) Choco Dream faces increasing marginal opportunity cost in the production of liquor chocolates.

Step-by-step explanation:

When Choco Dream increased their production of liquor chocolates by 500 units (to 4,500 bars per month), their opportunity was 800 units of dark chocolate. But when they needed to increase liquor chocolates by 500 more units (to 5,000 bars per month), then the opportunity cost increased to 1,000 units of dark chocolate.

That means that for the first 500 extra liquor bars, the opportunity cost = 800 dark chocolate bars / 500 liquor bars = 1.6 dark chocolate bars for every extra liquor bar.

The second increased required a higher opportunity cost = 1,000 dark chocolate bars / 500 liquor bars = 2 dark chocolate bars for every extra liquor bar.
