Answer: 660 cm²
Step-by-step explanation:
Surface area of a cylinder = 2πr² ± 2πrh = 2πr ( r + h )
π = 22/7
r = 6 cm
h = 11.5 cm
Lateral surface area = 2 x 22/7 x 6 ( 6 + 11.5 )
= 660 cm²
The answer is 158,400 because you time 90 by 50 by 32
Answer:
The expected number of interviews is 3.25.
Step-by-step explanation:
For each person applying for a profissional position, there are only two possible outcomes. Either they land an interview, or they do not. The probability of a person landing an interview is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
In this problem, we have that:
So
The expected number of interviews is 3.25.
