Answer:
x = −4
Step-by-step explanation:
Add x to both sides of the equation. x + 4 + x = − 4 Add x and x . 2 x + 4 = −4
Subtract 4 from both sides of the equation. 2 x = −4 − 4 Subtract 4 from - 4. 2x = −8
Divide each term in 2x = −8 by 2. 2x/2 = −8/2
Cancel the common factor. 2x/ 2 = −8/2 Divide x by 1. x = −8/2
Divide −8 by 2. x = −4
400 because the tens is a 8
Yes I think that is correct
Answer:
Mean: 8 and MAD: 1.2
Step-by-step explanation:
Given a data with :
Mean = 20 ; mean absolute deviation (MAD) = 3.1
DATA with a low mean and variability Than The above from the options given :
The most appropriate option is : Mean: 8 and MAD: 1.2 ; because both values of the mean and mean absolute deviation are lesser than the value given.
