Answer:

a. There is a causation relationship and positive trend between number of hours on homework and higher test scores.

b. 76

Step-by-step explanation:

a. Since the dots all follow a linear progression and increase closely together this is a positive trend and likely a causation relationship.

b. y=7x+41 can predict a test score. x is the number of hours, so if 5 if the number of hours then y=7(5)+41 = 35+41=76

Find the measure of the exterior angle.

MaRussiya [10]

Answer:

$120 \degree$

Step-by-step explanation:

The exterior angle in a triangle is equal to the sum of the interior opposite angles in a triangle

Therefore,

$90 + x = 4x$

Now solve for x

$90 + x = 4x \\ 90 = 4x - x \\ 90 = 3x \\ \frac{90}{3} = \frac{3x}{3} \\ 30 \degree = x$

Now let's solve for the exterior angle

$4x \\ 4 \times 30 \\ 120 \degree$

Hope this helps you.

Art [367]

Answer:

24.3

Step-by-step explanation:

area of a rectangle =length*width

if we know at least the 2 quantities already

total area = 656.1

and one of the sides = 27

we have to divide the are by one of the sides to get the remaining side

width = area/length

656.1 divided by 27 equals 24.3
