In a mathematics class, half of the students scored 42 on an achievement test. With the exception of a few students who scored 78, the remaining students scored 53. Which of the
following statements is true about the distribution of scores?

If half the students scored 42 and some scored 53, the median must be (53 + 42)/2 = 47.5.

If the other half all scored 53, the mean would be the same, but the few 78s is going to raise the mean.

The mode is 42.

i hope it helps you

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
