Using a calculator or statistical software, find the linear regression line for the data in the table below. Then, use the equation to estimate the value of y when x is 12. Round the values of a and b to the nearest hundredth, then use the equation to solve for y when x=12. Round the final answer to the nearest hundredth.

x y
3 3.44
4 5.84
5 8.23
6 6.38
7 9.06
8 9.06
9 9.87
10 11.36

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

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;
