Pat kept track of the number of hours that he spent at the park each week for several weeks. He spent 10, 4, 1, and 5 hours. What is the mean number of hours that Pat spent at the park each week? O A. 20 hours O B. 9 hours O C. 5 hours O D. 4 hours​

10

step-by-step explanation:

7+3=10

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2

next time, share the answer choices.   .

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
