If Ms. Jones’s division sees a 5 percent (or greater) revenue increase over last year, she will receive a $20,000 bonus. If her division sees a 0–5 percent revenue increase over last year, she will receive an $8,000 bonus. If the revenues in her division decrease relative to last year, she will receive no bonus. Assuming that the percentage revenue increase of the division is normally distributed with a mean of 3 percent and a standard deviation of 3 percent, what is the expected value of Jones’s bonus?

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

english maybe i can ..
