B, because if I don't see a chart, I will have to assume that these people are at or are around 18 years of age.
Answer:
Sum=24
Mean=8
Step-by-step explanation:
To find the sum of all the numbers you simply would do 8+7+9.
That is 24.
When finding mean you add up all your numbers then divide by the total number of number (I know that sounds a bit confusing. In this case there are only 3 numbers, so that is the one you will use for dividing)
Your equation would look like this
24
_
3
Once you divide you should get 8 as your mean or average in other terms.
17 multiplied by 8 is 136.
Answer:
Subtract 4 and then add 6.
Step-by-step explanation:
8-4=4
4+6=10
10-4=6
6+6=12
12-4=8
8+6=14
The rule for this pattern can be subtracting 4, and then adding 6.
Hope this helps always remember soh = sin cah = cos & toa = tan so remember you are looking for the opp and adj
