Answer:
55.8
Step-by-step explanation:
all ya gotta do is multiply the numbers together
The answer is 0.88889, because:
Order of Operations-
1) Add 30 plus 6 to get 36
2) Subtract 32 from 36 to get 4
3) Divide 4 by 9 to get 0.4444444
4) Multiply 0.4444444 by 2 to get 0.888889
Good luck! <3
Answer:
The answer is B.
Step-by-step explanation:
Answer:
y = -8x + 4
Step-by-step explanation:
In slope intercept form, y = mx + b, the slope is m and the y intercept is b.
Substitute -8 for m and 4 for b.
hope this helps :)
First we find the mean (average) by adding up all the numbers and dividing by how many numbers there are.
(21 + 10 + 15 + 19 + 8 + 17 + 15) / 7 = 105 / 7 = 15
now we find the absolute value of the difference between the data set and the mean
| 21 - 15 | = 6
|10 - 15 | = 5
|15 - 15 | = 0
|19 - 15 | = 4
|8 - 15 | = 7
| 17 - 15 | = 2
| 15 - 15 | = 0
now we find the mean (average) of these numbers
(6 + 5 + 0 + 4 + 7 + 2 + 0) / 7 = 24/7 = 3.43 <=== the MAD
