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

Answer:
x = 183
Step-by-step explanation:
(x -73)° + x° +67° = 360°
x-73+ x +67 = 360
x + x -73 +67 = 360
2x-6 = 360
2x = 360+6
x = 366÷2
x = 183
Check:
(183 - 73) = 110° , x = 183° , 67°
110° + 183° + 67° = 360°
Answer:
80 members
