Answer:
V = 2143.57
Step-by-step explanation:
To find the volume of a sphere you need to use this formula:

r = radius
Solve:
You need the radius from the diameter. Divide 16/2 which is
8.

V = 2143.57
Answer:
Step-by-step explanation:
Given that the random variable X is normally distributed, with
mean = 50 and standard deviation = 7.
Then we have z= 
Using this and normal table we find that
a) 
b) When z=0.02
we get

c) 90th percentile z value =1.645
90th percentile of X 
Answer: w= 1/5
Step-by-step explanation:
11/15=8/15 -w
-W= 8/15 -11/15
-w= 8-11/15 =-3/15
-w=-3/15
w=3/15= 1/5
Answer:
A= 16
P=16
Step-by-step explanation:
A=h^bxb/ 2
P= side+base+side
<span>Max ht is at the vertex of the parabola, at t = -b/2a
t = -32/-32 = 1
h(1) = -16 + 32 + 20
= 36 feet
hope this helps
