- Kirk is reading a book and found that after 5 days he had read 180 pages.
rate is Kirk reading the book in (b) If the book is 765 pages long, how many
days will it take him to read the book at
the rate you found in (a)?

Answers

Answer:

21.25 days

Step-by-step explanation:

We first need to find the rate that he read the book for the first 5 days:

180 (pages)/5 (days)= 36

So he reads 36 pages a day. Now we need to find how many days it will take him to read the whole book, while reading 36 pages a day.

765 (total pages)/36 (pages he reads in a day) = 21.25

Have a wonderful day, my friend.

What is the equation of the line in slope-intercept form?

Answers

Answer:

y = -3x + 4

Step-by-step explanation:

y = mx + b

y = y coordinate

m = slope (rise/run, up/over, change in y/change in x)

x = x coordinate

b = y intercept (where the line crosses the y-axis.

1. Write the equation                                                            y = mx + b

2. Substitute the numbers in the proper place.                y = 3/1 x + 4

3. Check for the type of slope- (positive or negative)      y = -3x + 4

    (Downhill slopes are always negative.)

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 84.584.5; this version has a mean of 66.966.9 and a standard deviation of 1111. Kiersten got a score of 281.8281.8; this version has a mean of 261261 and a standard deviation of 2626. Pierce got a score of 7.697.69; this version has a mean of 7.27.2 and a standard deviation of 0.70.7. If the company has only one position to fill and prefers to fill it with the applicant who performed best on the aptitude test, which of the applicants should be offered the job?

Answers

Answer:

Tobias should be offered the job.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

The applicant with the highest z-score should be chosen.

Tobias:

Score of 84.5, in a version with mean 66.9 and standard deviation 11. His z-score is found when [tex]X = 84.5, \mu = 66.9, \sigma = 11[/tex]

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

[tex]Z = \frac{84.5 - 66.9}{11}[/tex]

[tex]Z = 1.6[/tex]

Kiersten:

Score of 281.8, in a version with mean 261 and standard deviation 26. His z-score is found when [tex]X = 281.8, \mu = 261, \sigma = 26[/tex].

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

[tex]Z = \frac{281.8 - 261}{26}[/tex]

[tex]Z = 0.8[/tex]

Pierce:

Score of 7.69, version with mean 7.2 and standard deviation 0.7. His z-score is found when [tex]X = 7.69, \mu = 7.2, \sigma = 0.7[/tex].

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

[tex]Z = \frac{7.69 - 7.2}{0.7}[/tex]

[tex]Z = 0.7[/tex]

Due to the higher z-score, Tobias should be offered the job.

Answers

Required table is attached below :

Answer:

0.56

Step-by-step explanation:

Since they both have :

SAT score is the same ; quality of letter is the same ;

High school GPA is 1.5 points higher ;

Therefore, to determine how much Mary's GPA will be higher than Karen's :

Multiply the number of points by the Coefficient of high school GPA Given in the regression table attached below :

High school GPA Coefficient = 0.37635

Number of points = 1.5

= 1.5 * 0.37635

= 0.564525

= 0.56

You are the coach of a basketball team that is currently looking for new players. One of the criteria for selection as a player is that the person must be above a particular height. Ideally, you want your next player to be as tall as possible. However, you do not want to rule out any potential players by making the cut-off height too strict. You decide that accepting players within the top 2.5% height bracket will be reasonable for your team. Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in. Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team. you may find this standard normal table useful. Give your answer in inches to the nearest inch.
C= _____ in

Answers

Answer:

C = 75 in

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in.

This means that [tex]\mu = 69, \sigma = 2.9[/tex]

Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team.

This is the 100 - 2.5 = 97.5th percentile, which is X when Z has a pvalue of 0.975, so X when Z = 1.96.

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

[tex]1.96 = \frac{X - 69}{2.9}[/tex]

[tex]X - 69 = 1.96*2.9[/tex]

[tex]X = 74.7[/tex]

Rounded to the nearest inch,

C = 75 in

[tex]2H + 5P = 11.25[/tex]

[tex]H = 2.50[/tex] --- Hot dog

[tex]P = 1.25[/tex] --- Pretzel

Step-by-step explanation:

Represent hot dogs with H and Pretzels with P.

For Tina:

[tex]4H + 3P = 13.75[/tex]

For Doug:

[tex]2H + 5P = 11.25[/tex]

Solving for the price of both items:

We have:

[tex]4H + 3P = 13.75[/tex] --- (1)

[tex]2H + 5P = 11.25[/tex] --- (2)

Multiply (2) by 2

2 * ([tex]2H + 5P = 11.25[/tex])

-------------------

[tex]4H + 10P = 22.50[/tex] --- (3)

Subtract (3) from (1)

[tex]4H + 3P = 13.75[/tex]

[tex]4H + 10P = 22.50[/tex]

----------------------

[tex]4H - 4H + 3P - 10P = 13.75 - 22.50[/tex]

[tex]3P - 10P = 13.75 - 22.50[/tex]

[tex]-7P = -8.75[/tex]

Solve for P

[tex]P = \frac{-8.75}{-7}[/tex]

[tex]P = 1.25[/tex]

Substitute 1.25 for P in (2)

[tex]2H + 5P = 11.25[/tex]

[tex]2H + 5 * 1.25 = 11.25[/tex]

[tex]2H + 6.25 = 11.25[/tex]

Collect Like Terms

[tex]2H = 11.25-6.25[/tex]

[tex]2H = 5[/tex]

Solve for H

[tex]H = \frac{5}{2}[/tex]

x = 4 and y = 1

Step-by-step explanation:

The given equations are :

2x+5y = 13 ...(1)

3x-2y = 10 ...(2)

We can use elimination method to solve the given equations.

Multiply equation (1) by 3 and equation (2) by 2.

6x+15y=39 ...(3)

6x-4y=20 ...(4)

Subtract equation (3) from (4).

6x-4y-(6x+15y) = 20-39

6x-4y-6x-15y = -19

-19y=-19

y = 1

Put the value of y in equation (1).

2x+5y = 13

2x+5=13

2x=8

x = 4

So, the solution of the given equations are x = 4 and y = 1.
