The median is the value that is in the middle of a dataset.
The first step to find the median is to order the values from least to greatest:
7, 8, 11, 12, 13, 15.
Since the number of data is even, the median will be the average of the pair of values that is in the middle, in this case, 11 and 12:

The median of the data set is 11.5.
I think this is asking what power when the first number given is raised to it will equal the number within the parentheses. So, for example, the answer to the first question would be 5 because 2^5 = 32. 10^3 = 1000, so the answer is 3, and so on.
Answer:
108 months old.
Step-by-step explanation:
Year = 12 months
9 Years = 9 x 12 months
9 years = 108 months.
Answer:
x + 15
Step-by-step explanation:
9x + 25 + x + 5 = 180
9x + x + 25 + 5 = 180
10x + 30 = 180
10x = 180 - 30
10x = 150
x = 150÷10
x = 15.
1. The data are
<span>75, 38, 43, 120, 65, 48, 52
Adding them and dividing by the number of data gives the mean which is 63.
Arranging them from lowest to highest and taking the middle data gives the median which is 52.
Since no data is repeated, this means that there is no mode.
The answer is
</span><span>D) mean: 63, median: 52, no mode
2.The answer is
A) mean
3. The realistic data to represent the weight of books is
A) mean </span>
