For khan academy. Need help . Explain if you can
crimeas [40]

Answer:

y = 2/3x + 1.5

Step-by-step explanation:

The Formula for that is

y = mx + b

m = slope

b =  y -intercept

so to find the slope I would do y/x or rise over run

So your slope is 2/3 ( it goes up 2 and right 3 times)

Since the line is going up and not down, it is a positive slope

y = 2/3x + b

we need to find where the line crosses the  vertical / y-axis and it's at the point.... (0,<u><em>1.5</em></u>)

y = 2/3x + 1.5

Hope this helped a little!

Consider the following least-squares specification between test scores and the​ student-teacher ratio:
liraira [26]

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

Test score new income

= 557.8+36.42 ln (101)\\= 725.882

Increase = 0.362~0.36

Option B is right.
