Answer:
324 girls
Step-by-step explanation:
From the information given;
- Number of students = 864
- Staff members = 80
We are required to determine the number of girls in the school;
Total number of students is 864
Therefore;
Number of boys = 5/8(864)
= 540
Thus;
Number of girls = 864 - 540
= 324
Hence, there are 324 girls in the school
Answer:

Step-by-step explanation:
Assuming that Y1 and Y2 are independent exponential random variable with mean 3
where : U = Y1 + Y2 applying the property of exponential distribution sum of exponentials will follow a gamma distribution
i.e. ∝ = 2 , and β = 1
note : U = 2X
Hence probability distribution function X =
Fx (x) = p( X ≤ x )
= p( U ≤ 2x )
= Fu (2x)
probability density function X
f (x) = = 2 Fu (2x)

Answer:
Population of monkeys after 2 years = 3200
Step-by-step explanation:
Total number of monkeys at the start = 2975
Increase ratio of monkey population one year =
∴ New population of monkeys after 1 year=
Decrease ratio the next year =
∴ Population of monkeys after 2 years=
