The number of people in a car that crosses a certain bridge is represented by the random variable X, which has a mean value μx = 2.0, and a variance σx2 = 1. The toll on the bridge is $5.00 per car plus $1.00 per person in the car. The mean and variance of the total amount of money that is collected from a car that crosses the bridge are:

Mean = 7Variance = 1

Mean = 11Variance = 1

Mean = 2Variance = 1

Mean = 2Variance = .5

Mean = 7Variance = 2

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

hope to and hope that my answer is brainliest.(follow me )

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
