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

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
