Step-by-step explanation:
information from the range
If the range is 26 and the largest number is 31 then the smallest number is 31 - 26 = 5
Information from the median
The median must consist of 2 numbers because we have 6 integers for the data and median must consist of the middle 2. Since we are told that the median is 15 and we need 2 integers the other integer must be 15 as well..
So what do we know so far.
5 15 15 31
Information from the mean
There are six integers making up the series of numbers. The mean is 16. Therefore all 6 integers added together must be 6 * 16 = 96
What do we have so for?
5 + 15 + 15 + 31 = 66
What do the other two numbers sum to?
96 -66 = 30
Getting the answer.
The first number to try must be 13. It has to be below 15 (the median and odd. That's 13).
So now we have
5 13 15 15 ___ 31
But from the mean we need 30
30 - 13 = 17
And we have a winner because 17 is above 15.
Answer
5 13 15 15 17 31
Answer:
This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.
Now, the circunference of a circle can be written as:
C = 2*pi*r
where:
pi = 3.14
r = radius = half of the diameter = 3.5m/2 = 1.75m
Then replacing those values in the equation for the circumference we have:
C = 2*3.14*1.75m = 10.99 m.
And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)
We can safely round up the circumference to the next whole number, C = 11m
1. 64+28+21=113 sq. feet
2. 5x5=25 sq. ft.
