HELP ASAP FOR BRAINLIEST: The time required to finish a test in normally distributed with a mean of 60 minutes and a standard de

liubo4ka [24]

Answer:

<u>The z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%</u>

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

<u>z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%</u>

As a graduating senior, Chun Kumora of Manhattan, Kansas, is eager to enter the job market at an anticipated annual salary of $4

ludmilkaskok [199]

1. Chun Kumora's salary after 11 years will be <u>$63,117.6200</u>.

2. Chun Kumora's salary after 21 years will be <u>$93,429.4900</u>.

3. Chun must receive raise greater than <u>$42,640</u> ($41,000 x 1.04) for the next year and greater than <u>$44,345.6000</u> ($42,640 x 1.04) for the year after.

<h3>How are the future salaries determined?</h3>

The future salaries (values) can be determined using an online finance calculator that compounds with the sum of the average inflation rate of 2% and the cost-of-living raise of 2% for 11 and 21 years, respectively.

<h3>Data and Calculations:</h3>

Future Value in 11 years:

N (# of periods) = 11 years

I/Y (Interest per year) = 4% (2% x 2)

PV (Present Value) = $41,000

PMT (Periodic Payment) = $0

<u>Results</u>:

FV = $63,117.62 ($41,000 + $22,117.62)

Total Interest = $22,117.62

<h3>Future Value in 21 years:</h3>

N (# of periods) = 21 years

I/Y (Interest per year) = 4% (2% x 2)

PV (Present Value) = $41,000

PMT (Periodic Payment) = $0

<u>Results</u>:

FV = $93,429.49 ($41,000 + $52,429.49)

Total Interest = $52,429.49

the perimeter of a parrallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length. Find the length

Papessa [141]

L+L+(L-4)+(L-4)=72

4L-8=72
4L=80
L= 20

so W= 20-4 or 16

Hey, heres some homework I have no idea on.

Tems11 [23]

First, let’s start off by removing the two that don’t a a brother or sister. That leaves 10 people who do. The we calculate the access answers. They go in the middle. It’s 6. Then we have one more that has only a sister, put that at the S side. Then we have 3 more left that have only a brother, put them on the B side. Then you have 10 dots on the diagram for the 10 peoples that have a brother and/or a sister.

To conclude:
3 on B
6 in between
1 on S
