Musya8 [376]

Sarah,

Let x = cost of notebook

let y = cost of thumbdrive

For Troy 5x + 5y = 75

For Lisa 2x + 6y = 78

Troy's equation let's divide it by 5 and get

x+ y = 15 multiply by -2

-2x -2y = -30

2x + 6y = 78 Add equations

4y = 48

Solve for y. Then plug it in one of the original equations and solve for x. Check by plugging into the other original equations

sergey [27]

Answer:

A. 32.44

Step-by-step explanation:

Automobile owner has 40% chance for one accident in a year and 60% of zero accident in a year.

Let x is the loss of accident and y is the payment by insurer.

Y = 0 if X < 40,

x - 40 if 40 < x < 130

130 if x $\geq$ 170

Then, Var [y] = E y^2

Var [y] = 1052.16

E = 32.437.
