Answer:
Option B
Step-by-step explanation:
Given that the regression equation using least squares for test scores and student teacher ratio is
Test Score = 557.8 + 36.42 In (Income).
Say if 1% income is increased.
Let income be 100
New income = 101
Then we have
Test score original =
![557.8+36.42 Ln 100\\= 725.520](https://tex.z-dn.net/?f=557.8%2B36.42%20Ln%20100%5C%5C%3D%20725.520)
Test score new income
= ![557.8+36.42 ln (101)\\= 725.882](https://tex.z-dn.net/?f=557.8%2B36.42%20ln%20%28101%29%5C%5C%3D%20725.882)
Increase = 0.362~0.36
Option B is right.
I got 1/12th left
I changed all of the fractions to twelfths
4/12
6/12
9/12
16/12
James and Katya ate 10/12 of a sandwich
Ramon ate the last 2/12 and 7/12 of the next sandwich
Sianna ate the other 5/12 and 11/12 of the 3rd sandwich
So that means 1/12 is left
I hope that helps and you get it right

Answer:
First blank = 236
Second blank = 60
Third blank = 656
Step-by-step explanation:
For first blank; n = 20
f(n) = 7(20) + 96
= 236
For second blank; f(n) = 516
⇒ 516 = 7n + 96
⇒ n = 60
For third blank; n = 80
f(n) = 7(80) + 96
= 656
