Z*_Upper = (76 - 62.7)/2.5 = 5.32
Z*_Lower = (57 - 62.7)/2.5 = -2.28
The requirement is to get p(-2.28 < Z < 5.32) = p(Z<5.32) - p(Z<-2.28).
Use normal distribution table to get the answer for p and multiply with 100 to get the percentage.
The other questions are now easy for you to answer on your own. Hope it helps.

Answer:
20
Step-by-step explanation:
we expect to have the smae outcome so we just multiply the out puts by 5 to see what would happen after 125 draws
Answer:
![(5\pi-11.6)ft^2](https://tex.z-dn.net/?f=%285%5Cpi-11.6%29ft%5E2)
Step-by-step explanation:
Given:
Length of radius of circle = 5 feets
Length of perpendicular bisector = 4 feets
To find:
Area of the shaded portion of the circle
Solution:
As OD is perpendicular bisector of AB,
![AB=2AD=2(2.9)=5.8\,\,feets](https://tex.z-dn.net/?f=AB%3D2AD%3D2%282.9%29%3D5.8%5C%2C%5C%2Cfeets)
![\angle ODA=90^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20ODA%3D90%5E%7B%5Ccirc%7D)
Area of
= 1/2 (base) × (height) =
square feets
Area of sector AOBC =
square feets
Here, r denotes radius of circle
So,
Area of shaded portion = Area of sector AOBC - Area of
=
