Answer: The SST for the data set is 8.
Step-by-step explanation:
Since we have given that
Coefficient of determination (R²) = 0.25
SSE for the data = 6
SST = ?
As we know the formula for coefficient of determination:
Hence, the SST for the data set is 8.
Answer:
m<IHG=133°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m<ZHG+m<IHZ= m<IHG -----> by angle addition postulate
substitute the given values and solve for x
11x-1+24=12x+13
Combine like terms
11x+23=12x+13
Group terms that contain the same variable
12x-11x=23-13
x=10
Find the measure of angle IHG
substitute the value of x
m<IHG= 12(10)+13 =133°
