Does this measure of central tendency describe the data well?
You work for a pet-grooming service. You record the number of animals you groomed each day over a 10-day period: 7, 10, 8, 9, 7, 11, 8, 6, 7, and 9. You state that the typical number of animals that you can groom is the mean of 8.2 animals per day.
O Yes, because the mean always describes data well.
O Yes, because there are no outliers to skew the data.
O No, because it is not possible to groom 0.2 of an animal.
O No, because the most common number of dogs groomed is 7.
O Yes, because half of the time, it is possible to groom more than 8.2 and half the time less than 8.2.

Ответ:
c(-10)
Step-by-step explanation:
move all terms to left
(C)(c)-(2.5c+15)=0
get rid of perentheses
c-2.5c-15=0
we add numbers together and all variables
-1.5c-15+0
we move all terms containing c to the left all other terms to the right
-1.5c=15
c=15/-1.5
c=-10
