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.

A population of 40 rats living near a restaurant dumpster is growing at a monthly rate of 50%
goldenfox [79]

[(40 ÷ .5) Y] + 40

Parentheses are rat growth

Brackets are rat growth by how many years or just exclude that and the brackets if you don't need to know how many years are there are

The 40 is the amount of rats already there

Growth of rats plus the amount already there.

I'm probably wrong lol

Phillip watched a beach volleyball game from 1 P.M. to 1:20P.M. How many degrees did the minute hand turn?
ArbitrLikvidat [17]

Answer:

The minute hand covered 120 degrees

Step-by-step explanation:

Minute hand completes 1 round in 60 minutes

1 round =360^{\circ}

So, The minute hand covered degrees in 60 minutes = 360^{\circ}

The minute hand covered degrees in 1 minute = \frac{360^{\circ}}{60^{\circ}}

Phillip watched a beach volleyball game from 1 P.M. to 1:20P.M.

So, He watched it for 20 minutes

So,The minute hand covered degrees in 20 minutes =\frac{360^{\circ}}{60^{\circ}} \times 20 =120^{\circ}

Hence The minute hand covered 120 degrees

Solve the system of equations: y=2x-5. y=x^2-5
VikaD [51]

Answer:

(0, -5) and (2, -1)

Step-by-step explanation:

Since both equations have already been solved for y, the substitution method is the easiest approach here.  Set the two equations equal to each other:

y = 2x - 5 = x^2 - 5 = y

Focusing on the variable x only, we get 2x - 5 = x^2 - 5.

Adding 5 to both sides results in 2x = x^2.

Factoring this result, we get x(2 - x)  = 0, whose solutions are

x = 0 and x = 2.

Now find the corresponding y-values:

If x = 0, then y = 2(0) -5, or y = -5;

If x = 2, then y = 2(2) - 5, or y = -1

Writing the solutions as coordinate pairs:  (0, -5) and (2, -1)
