Jen looks up ten closest nail salons to her house and records their distances, in miles, from her house:

2.0, 2.1, 3.2, 3.3, 3.7, 3.8, 3.9, 4.0, 4.5, 4.8

what is the average distance from jen's house of the ten nail salons she looked up?

a) 2.57 miles
b) 2.80 miles
c) 3.53 miles
d) 3.75 miles

 Option 'C' is correct.

Step-by-step explanation:

Since we have given that  

Ten closest nail salons to her house are as follows:

2.0, 2.1, 3.2, 3.3, 3.7, 3.8, 3.9, 4.0, 4.5, 4.8

We need to calculate the average distance from Jen's house of the ten nail salons she looked up :

So,

Hence, Option 'C' is correct.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
