Aman is considering buying a one-year warranty for $100, which will cover the $600 replacement cost for his new swimming pool pump. the probability the pump does not break within the first year is 90%.

a) the expected value is −$90, so the man should not buy the warranty.
b) the expected value is $90, so the man should buy the warranty.
c) the expected value is −$40, so the man should not buy the warranty.
d) the expected value is $40, so the man should buy the warranty.

it'd me out a lot if you explained your answer!

C)The expected value is −$40, so the man should not buy the warranty.

Step-by-step explanation:

The expected value is( each value times the respective probability) minus the cost of the item

E = cost * probability + no cost * probability

   It will cost 600 dollars if it breaks * 10 percent chance it breaks

   It will cost nothing if it does not break * 90 percent chance it does not break

E = 600 * .1 + 0*90

E = 60 +0

E = 60

Now we subtract the 100 dollars for the warranty

E - 100

60-100

-40

Our expected cost is -40

C. The expected value is −$40, so the man should not buy the warranty.

May I have brainliest please? :)

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
