Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.
Answers
Answer:
Explained below.
Step-by-step explanation:
The complete question is:
Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.
1. P(Z < 1.62)
2. P(Z > -1.57)
3. P(-1.41 < Z < 0.63)
Solution:
Use Excel to solve the problems.
(1)
P(Z < 1.62) =NORM.S.DIST(1.62,TRUE)
= 0.9474
(2)
P(Z > -1.57) = P (Z < 1.57)
=NORM.S.DIST(1.57,TRUE)
= 0.9418
(3)
P(-1.41 < Z < 0.63) = P (Z < 0.63) - P (Z < -1.41)
=NORM.S.DIST(0.63,TRUE) - NORM.S.DIST(-1.41,TRUE)
= 0.7357 - 0.0793
= 0.6564

4. The value of a copy machine is $8500 when it is purchased. After two years its value is $7475. What is its value after 8 years?
Answers
Answer:
3375 is the answer.
Step-by-step explanation: 8500- 1025=7475
so 1025 is every to years so we need to subtract 7475-1025-1025-1025-1025 so each 1025 is 2 yrs.

The equation F= 9/5C +32 relates temperature measured in degrees Celsius. C, to degrees Fahrenheit, F. Determine whether there is a proportional relationship between C and F.
Answers
Given:
The equation is
[tex]F=\dfrac{9}{5}C+32[/tex]
To find:
Whether there is a proportional relationship between C and F.
Solution:
If there is a proportional relationship between C and F, then the line of given equation passes through (0,0) and the equation must be true for (0,0).
Put F=0 and C=0 in the given equation.
[tex]0=\dfrac{9}{5}(0)+32[/tex]
[tex]0=0+32[/tex]
[tex]0=32[/tex]
This statement is not true because [tex]0\neq 32[/tex].
It means the line of given equation does not passes through (0,0). So, it s not a proportional relationship.
Hence, there is not a proportional relationship between C and F.

I hope you helped☜☆☞Chloe prepared 28 kilograms of dough after working 7 hours. How much dough did Chloe prepare if she worked for 8 hours? Assume the relationship is directly proportional.
Answers
Answer:
Chloe prepared 32 kilograms if she worked for 8 hours.
Step-by-step explanation:
28 ÷ 7 = 4
4 kilograms per hour worked
4 × 8 = 32
Answer:
32 kilograms
Step-by-step explanation:
The proportion of kilograms of dough to the number of hours worked is [tex]\frac{28}{7}[/tex] which equals to 4 kilograms / hour.
You multiply 4 kilograms/hour by the number of hours she worked which is 8 hours so 4 kg/hour (8 hours) = 32 kilograms.

The length of a rectangle is 5cm less than twice the width. The perimeter is 44cm.
Answers
Answer:
Width = 9
Length = 13
Step-by-step explanation:
width = w
length = L
w(2) - 5 = L
w + w + L + L = 44
44 + 5 + 5 = 54
54/6 = 9
9(2) = 18 - 5 = 13
w = 9
l = 13
Check:
9 + 9 + 13 + 13 = 44
9(2) = 18 - 5 = 13

How to graph y=12-6x
Answers
Answer:
The answer will be listed below.
Step-by-step explanation:
This equation is in y=mx+b form, so to graph this equation, take the y-intercept which would be 12. Go on your graph and make twelve on the y-axis (you can go by two's or even six's). Then take your slope which would be -6 and use rise of run which would be down 6, since it's negative, and to the right one. Keep repeating this process until you ran out of space. Draw a line between the points and you have graphed a line.

Jenna has a piece of paper that is 99 3/4 square inch in Area.
It is 10 1/2 inches long.
What is the width of the piece of paper in inches?
Answers
Answer:
Width is 9 1/2 in.
Step-by-step explanation:
My reasoning is that, since youve gotten the area (99 3/4), your asked to find the width. You have the length which is 10 1/2. In this situation youre expected to divide. What you divide is 99 3/4 by 10 1/2. If you calculate this, you get a quotient of 9 1/2. I’m not very ethical at explanations, but I hope you found it helpful somehow.
