Answer:
Answer choice C
Step-by-step explanation:
Since x is between -2 and 10, it is greater than 2 and less than 10. You also know that the answer is option C and not B, because in the picture the blue line is rounded at the -2 and 10 marks, meaning that it does not quite reach them. Hope this helps!
The square root of 20 is irrational.
42 is 16, less than 20 and 52 is 25, more than 20.
Given:

To find:
The simplified expression by factoring.
Solution:
Let us factor the numerator:

31x can be written as 3x + 28x.

Take 3x common in 1st two terms and 7 common in next two terms.

Make sure the remaining terms in the both brackets must be same.
Now, take out common factor (4x + 1).

In the same way, factorize the denominator:

8x can be written as 4x + 4x.

Take 4x common in 1st two terms and 1 common in next two terms.

Make sure the remaining terms in the both brackets must be same.
Now, take out common factor (4x + 1).

Substitute the terms we found for numerator and denominator:

Cancel the common factors.

The simplified expression is

Hi I am here to help :). I think the answer would be 7/4. Good luck!
<u>Final Answer:</u>
mean = 4 sundaes
<u>Solution:</u>
each bowl of sundaes contains 3 sundaes.
- two scoops = 4 sundae bowls
- I scream = 6 sundae bowls
- dream scream = 2 sundae bowls
(plus 3, the number three represents how many sundae's there are in a bowl)
(divide it by 12, since there are 12 numbers in the data set)
Mean = (4 + 4 + 4 + 6 + 6 + 6 + 2 + 2 + 2 + 4 + 4 + 4) ÷ 12
= 48 ÷ 12 = 4
