Answer:
B. (2 + 5).
Step-by-step explanation:
18 + 45 = 63
The prime factors of 63 = 3*3*7
So 63 is a multiple of 7.
The answer is (2 + 5) (=7).
600. Because 50 is rounded up.
Complete Question
According to a study done by a university student, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267 Suppose you sit on a bench in a mall and observe people's habits as they sneeze
(a) What is the probability that among 18 randomly observed individuals exactly 6 do not cover their mouth when sneezing?
Answer:
Step-by-step explanation:
From the question we are told that:
Sample size
Probability
No. that do not cover their mouth when sneezing
Generally the equation for The Binomial distribution is mathematically given by
Parameters
B(18,0.267)
Therefore
Where
Therefore
If it’s v=1/3 *( a^2) * h
Divide both sides by (1/3)*h
v/(1/3*h) = a^2
Or
3v/h = a^2
Square root both sides
Sqrt(3v/h) = a
