Question

Over a 5-year period, a company reported annual profits of $8 million, $3 million, $2 million, and $9 million. In the fifth year, it reported a loss of $7 million. What was the mean annual profit?

$ _____ million

Answer 1

Does your book give you the definition of mean? If not, it is the sum of all the the data points divided by the number of data points. In this case it the sum of the profits, divided by the number of years.

Answer 2

8+3+2+9+7=28/5=5.6

Answer 3

very close. Take a look at the fifth year.

Answer 4

the annual profit

Answer 5

The fifth year is a loss. You did everything right in your 2nd post except for one detail. How you interpret a "loss" mathematically?

Answer 6

oh so its 4.2

Answer 7

Answer 8

well u just add the numbers up and divide them by the amount of numbers there are.

Answer 9

ya and it would be 4.2 right

Answer 10

i got 5.8...

Answer 11

$8 is a loss

Answer 12

oh wait so:
8 + 3 + 2 + 9 - 7?

Answer 13

indeed.

Answer 14

i got 5.8 also but $8 is a loss

Answer 15

8+3+2+8-7 all over 5

Answer 16

sorry, 8+2+3+9-7

Answer 17

so its actually 2.8

Answer 18

i typed 8 a 2nd time by mistake.

Answer 19

its 3.

Answer 20

i am so confused because i divided it and got a different answer

Answer 21

8+2+3+9 = 22. subtract 7, is 15. 15/5 is 3.

Answer 22

well it depends on what number u divide it by...if u include the number seven u will get a different score...im honestly confused my self because i kinda forgot this stuff..

Answer 23

The mean just means average. you just add up the number from each year, and divide by the number of years. \[\frac{ 8+2+3+9+(-7) }{ 5 }\]

Answer 24

sounds straight.
