H(x) = 1/9000x^2 - 7/15x + 500 = 1/9000(x^2 - 4200x + 4500000) = 1/9000(x^2 - 4200x + 4410000 + 90000) = 1/9000(x - 2100)^2 + 1/9000(90000) = 1/9000(x - 2100)^2 + 10
h(x) = 1/9000(x - 2100)^2 + 10
Answer:
-- Component A
-- Component B
Step-by-step explanation:
Given
Distribution = Exponential
--- Component A
--- Component B
Solving (a): The mean time of A
The mean of an exponential distribution is:

We have:
--- Component A

Solving (b): The mean time of B
The mean of an exponential distribution is:

We have:
--- Component B

The answer is 194.4 cubic units
If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
(40 - x)(36) + (52)(48) = C
Rearranging the equation gives,
x = 40 - ((C - 2496)/ 36)
