Answer:
Hey there!
The formula for cylinder volume is , where r is the radius, h is the height, and
is a constant, roughly equal to 3.14.
Substituting all of these values into the equation:
Thus, the volume for the cylinder is 804.84 units cubed.
Hope this helps :)
Answer:
Step-by-step explanation:
X no of questions student answers is binomial with n =40 and p =0.5
If approximated to normal, X is Normal with
mean = np = 20 and variance = npq = 10
P(X>N) >0.10
We use std normal distribution table to get z value first then convert to x value
So
This is with continuity correction.
Hence without continuity correction this equals 7.2-0.5 = 6.7
x>6.7
n = 7
