X=2 or -7(answer choice A)
IgorLugansk [536]3 years ago

A) 2, -7

This is because you can view each (x-2) and (x+7) as a number. Thinking like this you have two numbers multiplied together to give you 0. The only way to multiply two numbers and get 0 is if either one or both of the numbers are 0. (As anything times 0 is 0.) So:

(x - 2) could be 0   or   (x + 7) could be 0

Mathematically:

x - 2 = 0           and            x+ 7 =0
   +2    +2                               -7   -7
x = 2                                  x = -7

I need help with box and whisker plots ASAP
bonufazy [111]
Box and whiskers plots use five number summaries. The first number is:
1:Minimum
2.Quartile 1
3.Mean
4.Quartile 2
5.maximum

Quartile are simple to get.
If your set of numbers is:
2,3,3,6,8,8,11
Then find the mean
2 3 3 |6| 8 8 11
Find the mean of the left side of of mean.
2 |3| 3 3 =Quartile 1
Then the right side
8 |8| 11 8 =Quartile 2
-----------------------------------------------
Your 5 number summary is 2,3,6,8,11
Plot them on the number line, but put a line above where the dot would go. take the 3 middle lines and connect to make a box. The lines on the outside of the box are the whiskers, AKA distributed data.

For every 9 black and white copies printed there are 2 color copies printed. If there are 200 color copies printed how many blac
alexandr402 [8]

Answer:

<u>900</u> black and white copies are printed.

Step-by-step explanation:

Given:

For every 9 black and white copies printed there are 2 color copies printed.

If there are 200 color copies printed.

Now, to find the number of black and white copies are printed.

Let the number of black and white copies printed be x.

As given, for every 9 black and white copies printed there are 2 color copies printed.

So, 9 is equivalent to 2.

If there are 200 color copies printed.

Thus, x is equivalent to 200.

Now, to solve by using cross multiplication method:

\frac{9}{2} =\frac{x}{200}

<em>By cross multiplying we get:</em>

1800=2x

<em>Dividing both sides by 2 we get:</em>

900=x

x=900.

Therefore, 900 black and white copies are printed.
