Step-by-step explanation:
Answer: MAD= 3
Step-by-step explanation:
Find the mean of the data set
31+24+32+28+29+36/6= 30
subtract EACH data by the mean, find the absolute value of the answer
31-30= 1 (absolute value)
24-30= 6 (absolute value)
32-30= 2 (absolute value)
28-30= 2 (absolute value)
29-30= 1 (absolute value)
36-30= 6 (absolute value)
Now find the mean of the values
1+6+2+2+1+6/6=3
MAD=3
Answer:
9x
Step-by-step explanation:
(x² + 2x) - (x² - 7x) ← distribute parenthesis
= x² + 2x - x² + 7x ← collect like terms
= 9x
