Answer:
m∠S = 29.5
Explanation:
      Q
S  R
 R
In this triangle, QR = SQ, which means its an isosceles triangle, angle S and R is similar.
<u>Thus solve:</u>
m∠S = (180° - 121°)/2
m∠S = 29.5°
 
        
                    
             
        
        
        
Answer:
X is the GPA 
Y is the Salary 
Standard deviation of X is 0.4
Standard deviation of Y is 8500
E(X)=2.9
E(Y)=47200
We are given that The correlation between the two variables was r = 0.72
a)


So, slope =  15300
Intercept =  2830
So, equation : 
b) Your brother just graduated from that college with a GPA of 3.30. He tells you that based on this model the residual for his pay is -$1880. What salary is he earning?

Observed salary = Residual + predicted = -1860+53320 = 51440
c)) What proportion of the variation in salaries is explained by variation in GPA?
 The proportion of the variation in salaries is explained by variation in GPA =
