Answer:
x= -35.153846
Step-by-step explanation:
360=200-5(x+37)
360=195(x+37)
360=195x+7215
360-7215=195x+7215-7215
-6855=195x
-6855/195=195x/195
-35.1538461538=x
-35.153846=x

Answer:
The mean.
Step-by-step explanation:

Because there are no outliers here, the mean is better.
Hopefully I helped :)
