For a certain health insurance policy, losses are uniformly distributed on the interval [0, b). The policy has a deductible of $180 and the expected value of the unreimbursed portion of a loss is $144. Calculate b.

b = 450

Step-by-step explanation:

Given that:

for a certain health insurance policy; Losses are uniformly distributed on the interval (0, b)

If the policy has a deductible value of $180      &

the expected value of the unreimbursed portion of a loss E(x)= $144

Then; b whican be calculated as:

we know that E(x) = 144

thus;

-36 b = -16200

b = -16200/-36

b = 450

1

step-by-step explanation:

it's the only multiple of both and the least

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
