Answer:
8
Step-by-step explanation:
the degree is the highest exponent value
The height will be 4 cm.
Explanation
<u />The volume of a cylinder is given by the formula V=πr²h. For a volume of 36π cm³ and a radius of 3 cm,
36π = π(3²)h
36π = 9πh
Divide both sides by 9π:
36π/9π = 9πh/9π
4 = h
Answer: 7.94
Step-by-step explanation:
The formula to calculate the standard deviation for binomial distribution :-
, where n is the number total of trials and p is the probability of getting success in each trial.
Given : The probability of the population has a particular genetic mutation=0.1
If 700 people are randomly selected, then the standard deviation for the number of people with the genetic mutation in such groups of 700 will be :-

Hence, the standard deviation for the number of people with the genetic mutation in such groups of 700 = 7.94
