Which expression is not equivalent to the other three?
Kitty [74]
The right answer is B.

The first step to answering this question is combining all like terms.

A. 2x + 2 + 2x + 3x - 8
The like terms in this expression are the x terms and the constants
So, what you would do is combine all of the x terms and combine all of the constants

(2x + 2x +3x) + (2 - 8)
7x - 6

B. 4 + 7x - 2
In this expression, you would combine all of the constants

7x + (4 - 2)
7x + 2

C. -2 + 5x + 2x - 4
For this expression, you would again, combine all of the x terms and all of the constants.

-2 + 5x + 2x - 4
(5x + 2x) + (-2 - 4)
7x - 6

D. 8x - x - 6
For this expression, you would combine all of the x terms

8x - x - 6
(8x - x) - 6
7x - 6

Now let's look at all of the new answer choices:
A. 7x - 6
B. 7x + 2
C. 7x - 6
D. 7x - 6

The question is asking you to find the one expression that's different. The only different one is B, so that's the answer.

Snezhnost [94]

Answer:

82.5% and 17.5%

Step-by-step explanation:

The telemarketer made 200 phone calls and only 35 people signed up. Therefore, we need to find the amount of people who didnt.

200 - 35 = 165

165 people did not sign up.

This meants that the frequency of getting a customer is 35/200 and not is 165/200. In percentages,

The relative frequency of not getting a customer is 82.5%

The relative frequency of getting a customer is 17.5%
