Answer:
Grace should use her phone for 58 minutes to maintain an average of 55 minutes.
Step-by-step explanation:
Usage of first month = 43 minutes
Second month = 62 minutes
Third Minutes = 57 minutes
Let, the usage of fourth month = k minutes
Mean of the data = 5 minutes
Now, Average of a Data = 
⇒
or, 55 x 4 = 162 + k
⇒ 220 - 162 = k
or, k = 58 minutes
So, Grace should use her phone for 58 minutes to maintain an average of 55 minutes.

The median for a set of numbers would be the one that appears closest to the middle of the set.
For the set 4, 8, 10, 5, 9, in order to find the median, we must first sort them numerically.
4, 5, 8, 9, 10
Now, which of these 5 numbers is the closest to the middle?
The answer to that would be 8, since it is actually the number in the middle.
The median number for the numbers 4, 8, 10, 5, 9 is 8.
Hope that helped =)
Answer:
A fraction is a number consisting of one or more equal parts of a unit. It is denoted by the symbol a/b, where a and b≠0 are integers (cf. Integer). The numerator a of a/b denotes the number of parts taken of the unit; this is divided by the number of parts equal to the number appearing as the denominator b.
