To find the mean you add up all the numbers and divide that amount by the amount of numbers. Which looks like this:
7 + 20 + 8 + 15 + 10 + 17 + 7 + 13= 97
97 divided by 8 = 12.125
The mean is 12.125.
To find the median you first need to put the numbers in order and then try to find the number in the middle. If there is two numbers in the middle those two numbers are still the median:
7, 7, 8, 10, 13, 15, 17, 20,
The median(s) are 10 and 13.
The 2 is the hundredths value.

Their net monthly income is $6008.08.
We start with Mrs. McConnell. She is paid twice monthly, so her monthly income (after taxes and deductions) is $3120.
For Mr. McConnell, we first determine how much he is paid per week. He gets 40 hours per week and is paid 25.07/hr; therefore he makes
40(25.07) = 1002.8 per week.
He is paid every other week (about twice a month), so his check on payday (before deductions) is 1002.80(2) = 2005.60. Taking out the deductions from his payday, his net income is 2005.60-561.56=1444.04. This makes 2888.08 per month for him.
Together, they make 2888.08+3120 = $6008.08.
Answer:
Step-by-step explanation:
y=-3/2(x+2)(x-4)
=-3/2(x²-4x+2x-8)
=-3/2(x²-2x-8)
=-3/2(x²-2x)-3/2×-8
=-3/2 (x²-2x+1-1)+12
=-3/2(x-1)²+3/2+12
=-3/2(x-1)²+27/2
