Answer:
(a) 81st
=NORM.INV(0.81;0;1)
![0.878](https://tex.z-dn.net/?f=%200.878)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
![0.706](https://tex.z-dn.net/?f=%200.706)
(d) 24th
=NORM.INV(0.24;0;1)
![-0.706](https://tex.z-dn.net/?f=%20-0.706)
(e) 11th
=NORM.INV(0.11;0;1)
![-1.227](https://tex.z-dn.net/?f=-1.227)
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
For this case we can find the percentiles with the Norm.inv function in Excel and we got:
(a) 81st
=NORM.INV(0.81;0;1)
![0.878](https://tex.z-dn.net/?f=%200.878)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
![0.706](https://tex.z-dn.net/?f=%200.706)
(d) 24th
=NORM.INV(0.24;0;1)
![-0.706](https://tex.z-dn.net/?f=%20-0.706)
(e) 11th
=NORM.INV(0.11;0;1)
![-1.227](https://tex.z-dn.net/?f=-1.227)
Answer: 5
Step-by-step explanation:
13-8=5
5-13=8
67 is the answer to the question
Answer:
Step-by-step explanation:
The easiest way to complete this is too use this data and put it into point-slope form. This is written as, y-y1=m(x-x1)
In this equation y1 is the y- coordinate of your point and x1 is the x-coordinate. M in this case would also be known as the slope.
Now we can submit our data-----
y-4=-5(x-5) -------- simplify
y-4=-5x+25 --------
y=-5x+28
It would be in a state of loss because the units manufactured neither reaches nor exceeds the break even point.
