Answer:
13.3
Step-by-step explanation:
There is an equation that helps
mean= (All of the numbers in the data added) divided by (the number of numbers in the data)
What that mean is:
1.) Add 20, 5, 7, 17, 16, and 15
2.) divided by 6 (because there is 6 numbers in the data)
3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)
which in this case it should be 13.33333...=13.3
Answer: $30 and 1 cent more
$60.50 - $30.50 = $30
0.12 - 0.11 = 0.01
I hope this helps.
Mode is the number that shows up the most
in this case, it is 71,500 which shows up twice, one more than any of the other numbers
hope this helps
Looks complicated, sorry wish I could help
You have to take $8,550 times 0.12 (12%) to find out the number it is being decreased by.
8,550 x 0.12 = 1,026
And then, you have to subtract 1,026 from 8,550 three times for three years and your answer becomes 5,472.
$5,472
