1. In the data set below. what is the mean? 9. 4. 9. 2, 8, 2, 1 a. 4.5 b. 5 c. 6 d. 3.4​

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
