Consider the following least squares specification between test scores and the student - teacher ratio: TestScore = 557.8 + 36.4
GenaCL600 [577]

Answer:

Test score_i= 557.8 +36.42 Income

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

Test score_f = 557.8  + (36.42* 1.01 Income)= 557.8 +36.7842 Income

And the net increase can be founded like this:

Test score_f -Tet score_i = 557.8 +36.7842 Income- [557.8 +36.42 Income] = 36.7842 Income -36.42 Income = 0.3642

So then the net increase would be:

C. 0.36 points

Step-by-step explanation:

For this case we have the following linear relationship obtained from least squares between test scores and the student-teacher ratio:

Test score_i= 557.8 +36.42 Income

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

Test score_f = 557.8  + (36.42* 1.01 Income)= 557.8 +36.7842 Income

And the net increase can be founded like this:

Test score_f -Tet score_i = 557.8 +36.7842 Income- [557.8 +36.42 Income] = 36.7842 Income -36.42 Income = 0.3642

So then the net increase would be:

C. 0.36 points

Hello!

First you to do 65 * 0.20

0.20 is 20% as a decimal

65 * 0.20 = 13

$13 is how much John saves.

To find out how much the skateboard cost you subtract how much he saved by the cost of the skateboard

65 - 13 = 52

The skateboard cost $52

Hope this helps!
