main answer : the normal distribution of given graduate record exam is 1,A(1)=0.3413
supporting answer:Because of its flared shape, a graphical representation of a normal distribution is sometimes referred to as a bell curve. The precise shape varies depending on the population distribution, but the peak is always in the middle and the curve is always symmetrical. The mean, mode, and median of a normal distribution are all the same.
body of the answer: given that x₁=mean+standard deviation
given mean₁=462
standard deviation =119
x₁=462+119=581
z₁=581-462/119=1
A(1)=0.3413
given mean₂=584
standard deviation=151
x₂=584+151
=735
z₂=735-584/151
=1
A(1)=0.3413
final answer:there fore both scores are normal

Area = width * height
since the window is 20 inches higher than the width:
width +20 = height
640 = width * width+20
640 = width^2 +20*width
width^2 +20*width - 640 = 0
width = 17.203
**********************************************************
Double Check
if width = 17.203 then height = 37.203
area = 17.203 * 37.203 = 640 square inches Correct!!
Answer:
2*3 = 6
3.18*6 = $19.08
Lidless is going to be around $16
65-9=56
56 divided by 8 is 7
So they will need 7 tents
It's 78.38
You have to square root
