Ratio of boys to girls = 1 : 3
Unknown constant = x
x + 3x = 24
4x = 24
x = 6
No. of girls = 3 x 6 = 18
The coefficient of determination is 0.65.
According to the given question.
For a regression analysis,
SST = 120
and, SSE = 42
Since, coefficient of determination for a regression analysis = SSR/SST
So,
SSR = SST - SSE
⇒ SSR = 120 - 42
⇒ SSR = 78
Therefore, the coefficient of determination for the given regression analysis
= 78/120
= 0.65
Hence, the coefficient of determination is 0.65.

Here is the answer for your problem. You will first need to divide by negative four to isolate the Y as it’s own variable. Then, there is the problem of that 3/4x on your left side. By subtracting it from both sides, you are isolating your Y all by itself and solving for Y.
Where are the variables for the equation?
Answer: y=12
Step-by-step explanation:
96=8y
96/8=y
12=y
