HURRY BNOW AM GONNA GIVE BRAINLIEST :D The table shows the performance ratings for technicians with years of experience with one company.

(EXPERIENCE OF TECHNICHIANS IN YEARS: 16, 12, 18, 4, 3, 10, 5, 12)

(PERFORMANCE RATING: 86, 88, 90, 67, 78, 81, 75, 83)

Write the least squares regression equation that models the data. Let x = years experience and let y = performance rating. (use a calculator if u need)

Use the equation to estimate the performance rating for someone with 25 years of experience. You must show your work.

answer is 144

step-by-step explanation:

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
