Answer:

see below

Step-by-step explanation:

An x-intercept is a place where the graph crosses the x-axis. This graph crosses the x-axis at -2, -1, 1, and 2. The coordinates of these points are ...

(-2, 0)
(-1, 0)
(1, 0)
(2, 0)

Of these, only one is listed among your answer choices: (-1, 0).

Challenger Elementary School has 800 students. Every Wednesday, 12 percent of the students stay after school for Chess Club.

DENIUS [597]

Let's set up a proportion.

$\frac{x}{800} \frac{12}{100}$

Then solve for x:
12 x 800 = 9600
9600/100 = 96

96 is 12% of the 800 students. :)

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

A right rectangular prism is shown.

So what you are looking for is the hypotenuse of the triangle DCF.

We know DC is 3cm, so we need CF.

BC and CF and CF create a right triangle.

Using Pythagorean Theorem, CF is about 10.2

Now using Pythagorean Theorem again, 3^2 +10.2^2=113

The sqaureroot of that is 10.6. So 10.6 is your answer

A rack of 15 billiard balls is shown. If one ball is selected at random, determine the odds against it containing a number grea

andre [41]

Using the probability and odds concepts, it is found that the odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .

A probability is the number of desired outcomes divided by the number of total outcomes.
An odd is the number of desired outcomes divided by the number of non-desired outcomes.

In the rack, there are 15 balls, numbered from 1 to 15. Of those, 6 are less than 7(against it containing a number greater than or equal to 7 is equivalent to it containing a number less than 7), thus:

There are 6 desired outcomes.
There are 9 non-desired outcomes.

The odd is:

$\frac{6}{9} = \frac{2}{3}$

The odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .
