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?
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.
In a math class with 20 students, a test was given the same day that an assignment
was due. There were 12 students who passed the test and 13 students who completed
the assignment. There were 10 students who passed the test and also completed the
assignment. What is the probability that a student chosen randomly from the class
passed the test and completed the homework?
=1/2
The probability that a student chosen randomly from the class
passed the test and completed the homework is [tex]\frac{1}{2}[/tex].
What is probability?"Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen."
Given
Number of students in a math class = 20
Number of students who passed the test = 12
Number of students who completed the assignment = 13
Number of students who passed the test and also completed the
assignment = 10
Formula to find probability of an event
Probability = [tex]\frac{Number of Favorable Outcomes}{Total Number of Favorable Outcomes}[/tex]
The probability that a student chosen randomly from the class
passed the test and completed the homework
= [tex]\frac{Number of Students Passed the Test and Completed the Homework }{Total Number of Students}[/tex]
= [tex]\frac{10}{20}[/tex]
= [tex]\frac{1}{2}[/tex]
Hence, the probability that a student chosen randomly from the class
passed the test and completed the homework is [tex]\frac{1}{2}[/tex].

This figure was broken into a triangle and a rectangle as
shown.
Use the figures to complete the statements
The height of the triangle h is __ cm
The area of the triangle is __ cm
The area of the rectangle is __ cm
The area of the irregular figure is __ cm
Answer:
The height of the triangle is 8 centimeters.
The area of the rectangle is 48 square centimeters.
The area of the rectangle is 216 square centimeters.
The area of the irregular figure is 264 square centimeters.
Step-by-step explanation:
The height of the triangle is the total height of the figure minus the height of the rectangle, that is:
[tex]h = 26\,cm - 18\,cm[/tex]
[tex]h = 8\,cm[/tex]
The height of the triangle is 8 centimeters.
The area of the triangle ([tex]A[/tex]), measured in square centimeters, is determined by the following formula:
[tex]A = \frac{1}{2}\cdot b\cdot h[/tex] (1)
Where:
[tex]b[/tex] - Base of the triangle, measured in centimeters.
[tex]h[/tex] - Height of the triangle, measured in centimeters.
If we know that [tex]b = 12\,cm[/tex] and [tex]h = 8\,cm[/tex], then the area of the triangle is:
[tex]A = \frac{1}{2}\cdot (12\,cm)\cdot (8\,cm)[/tex]
[tex]A = 48\,cm^{2}[/tex]
The area of the rectangle is 48 square centimeters.
The area of the rectangle ([tex]A[/tex]), measured in square centimeters, is determined by the following formula:
[tex]A = b\cdot H[/tex] (2)
Where [tex]H[/tex] is the height of the rectangle, measured in centimeters.
If we know that [tex]b = 12\,cm[/tex] and [tex]H = 18\,cm[/tex], then the area of the rectangle is:
[tex]A = (12\,cm)\cdot (18\,cm)[/tex]
[tex]A = 216\,cm^{2}[/tex]
The area of the rectangle is 216 square centimeters.
The area of the irregular figure is the sum of the areas of the rectangle and the triangle. Then, the area of the irregular figure is 264 square centimeters.
Answer:
This figure was broken into a triangle and a rectangle as shown.
A figure can be broken into a rectangle and triangle. The rectangle has a base of 12 centimeters and height of 18 centimeters. The triangle has a base of 12 centimeters and height of 8 centimeters.

Answer: The answer is A. y = - 7/4 + 4
Step-by-step explanation: First you find the y-intercept which in this case is positive 4 which eliminates D as an option. Then looking at slope you have to remember rise/run as a rule of thumb. Rise meaning up or down on the graph and run meaning across. Because the line is going to the left we know that the slope has to be negative which eliminates C as an option. So now from your y-intercept (positive 4 on the y axis) you count 7 ticks down and see that the point is 4 ticks to the left which eliminates B as an answer option. Now, you have you answer which is A.
