anzhelika [568]

Answer:

A. Positive

Step-by-step explanation:

They ask us about the relationship between reading and grades.

First you have to go to the first part of the statement that says:

"Dr. Yancy conducted a correlation study in which she found that the more time children in her study read at home the better they performed in school"

In this case they tell us that there is a positive correlation, that the more you read the better your performance in school is.

Performance is your grades, and home study can be reading, so the score is positive in the second half, too.

Round to the nearest tenth if necessary. Find the distance between the two points. (–1, –8), (–4, –4) A)5 B)25 C)13 D)1
jeyben [28]

Answer: (a)

Step-by-step explanation:

Given

The points are (-1,-8) and (-4,-4)

The distance between two points (x_1,y_1),(x_2,y_2) is given by

d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

Apply the distance formula

\Rightarrow d=\sqrt{\left( -4+1\right)^2+\left( -4+8\right)^2}\\\\\Rightarrow d=\sqrt{(-3)^2+(4)^2}\\\Rightarrow d=\sqrt{9+16}\\\Rightarrow d=5\ \text{units}

Hence, option (a) is correct.
