The least square regression equation for the information provided is y = 9.72x - 40.776
<u>The general equation of a regression model can be expressed thus</u>:
Calculating slope, b :
- b = 0.81(177.6 / 14.8) = 9.72
<u>Plugging the values of b, y and x into the equation in other to calculate c</u> :
696 = 9.72(75.8) + c
696 = 736.776 + c
c = 696 - 736.776
c = - 40.776
Therefore, the linear regression model can be expressed as : y = 9.72x - 40.776

I believe the answer would be 62.00.
You would want to divide 30 by 2/3 so you would do 30/1 times 3/2. This method is known as keep change flip or kcf (Kentucky Chicken Fried is what some people say) your final answer should come out to 90/2 which simplified is 45. Hope this helped
