KTwo dices are rolled let x be a random variable denoting the absolute value of the different of outcomes in the two dice construct the possible distribution x
Compute the expected value and variance of x

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

2 over 5 and 4 over 15

don’t know last one sorry
