I really need help with this problem, I don't know how to do it. Please help if you can.
Stels [109]

Answer:

see below

Step-by-step explanation:

2/3 +y =1/4

Subtract 2/3 from each side

2/3-2/3 +y =1/4-2/3

y = 1/4 -2/3

Get a common denominator

y = 1/4 (3/3) - 2/3 *4/4

  = 3/12 - 8/12

  =-5/12

or if

2/(y+3) = 1/4

Using cross products

y+3 = 2*4

y+3 = 8

y =8-3

y = 5

You insurance policy on your car costs $600 a year. If you total your vehicle, you insurance company will pay $25,000 towards a
vladimir2022 [97]

Answer:

Your annual expected value is -$550.

Step-by-step explanation:

0.002 probability that you will total your car.

If you total your car, you pay the insurance of $600, but you get the $25,000 insurance. So in total, the net value will be $24,400.

1-0.002 = 0.998 probability that you will not total your car.

In this case, you lose $600.

What is your annual expected value?

Multiply each net value by it's probability.

E = 0.002*24400 - 0.998*600 = -550

Your annual expected value is -$550.
