Hello your question has a disjointed equation attached to it and it is also incomplete attached below is the correct and complete question

A teacher believes that the third homework assignment is a key predictor in how well students will do on the midterm. Let x represent the third homework score and y the midterm exam score. A random sample of last terms students were selected and their grades are shown below

answer :

y-intercept = 25.9047

 slope = 2.8420

Step-by-step explanation:

Determine the slope for the regression equation and y intercept

The regression equation ( gotten using excel ; attached below is the excel sample on how the equation was gotten )

y = 25.9047 + 2.8420x

from the equation gotten above

y-intercept = 25.9047

slope = 2.8420

2 1/5 /10 = x/4, using proportions, solve for x, and explain.
lisov135 [29]

Answer:

x = 22/25

Step-by-step explanation:

Given

2 1/5            x

---------- = -----------

10              4

Using cross products

2 1/5 * 4 = x*10

Change 2 1/5 to an improper fraction

2 1/5 =(5*2+1)/5 = 11/5

11/5 *4 = 10x

44/5 =10x

Multiply each side by 1/10 to isolate x

44/5 *1/10 = 10x * 1/10

44/50 = x

Divide top and bottom by 2

22/25 = x

Answer:

y=-3/4x+3

Step-by-step explanation:

the slope is -3/4

in this case, y=mx+b

so y=-3/4x+b

b is the y intercept, so it would be 3

altogether, y=-3/4x+3
