There is a positive correlation between the hours of homework and the test scores. Generally the more hours spent on homework the the higher score on the test

Answer:

<h2>Positive linear correlation.</h2>

Step-by-step explanation:

According to the graph, both variables are showing a positive linear correlation. We can deduct this by observing the trend of all points, they are raising, there we could apply a linear regression to find the average linear function that models this case.

However, we just can deduct that there's a positive correlation, to find further details we would need more data.

Remember that a positive linear correlation refers to the increasing behaviour of the dependent variable, while the independent variable also increases. That is, while one variable increases, the other also increases, that's called a positive correlation.

Which value below is included in the solution set for the inequality statement?

mixas84 [53]

You haven't provided any value, but I can tell you the solution set for the inequality.

First of all, expand both sides:

$-3x+12 > 6x-6$

Add 3x to both sides:

$12 > 9x-6$

Add 6 to both sides:

$18 > 9x$

Which is of course equivalent to

$9x < 18$

Divide both sides by 9

$x < 2$

So, every number smaller than 2 is part of the solution of this inequality.

a tub shaped like a cylinder with a diameter of 18 inches, And a height of 20 inches Is filled to the top with water. Six spheri

jasenka [17]

The approximate amount of water that remains in the tub after the 6 spherical balls are placed in the tub are 3479.12 in³.

<h3>What is the approximate amount of water that remains in the tub?</h3>

The first step is to determine the volume of the cylinder.

Volume of the tub = πr²h

Where:

r = radius = diameter / 2 = 18/2 = 9 inches
h = height
π = 3.14

3.14 x 9² x 20 = 5086.8 in³

The second step is to determine the volume of the 6 balls.

Volume of a sphere= 4/3πr³

r = diameter / 2 = 8/2 = 4 inches

6 x (3.14 x 4/3 x 4³) = 1607.68 in³

Volume that remains in the tub = 5086.8 in³ - 1607.68 in³ = 3479.12 in³

What is the value of x?

uranmaximum [27]

Answer:

$x=\frac{160-51}{2} =54.5$ °

Step-by-step explanation:

"Theorem 9-13: The measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside the circle is equal to half the difference of the measures of the intercepted arcs."

Basically no matter what other circle, secant or tangent you get, you just use the formula $Outer\angle=\frac{far.point - near.point}{2}$

If you need the outer angle, just put the other angles in and solve

If you need the far or near point angle, re-arrange the formula to get that value.
