Answer:
It's B, 62.
First, you identify the median, (30,) and use this to identify the first and third quartiles. 2-18 are the first ranges, and 42-81 are the third.
You would need to split the ranges between the first quartile (9) and the third quartile (71).
The interquartile range is the difference between the first and third ranges, making it 62.
Answer:
20 1/3
Explanation:
The number of possible groups or combination of three men can be formed from 10 is 120.
According to the given question.
Total number of men in a company, n = 10.
Number of men to be selected, r = 3
As we know that, What is a combination in math?
Image result for what is combination
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Therefore, the number of possible groups or combination of three men can be formed from 10
=
= 10!/ 3!7!
= 10(9)(8)/3(2)
= 5 × 3 × 8
= 120
The number of possible groups or combination of three men can be formed from 10 is 120.

Answer:
So the coordinates of M are (8.5,2.17)
Step-by-step explanation:
To obtain a 3:5 ratio, the x coordinate of M is 3/5 of the way between the x-coordinate of X (1) and the x-coordinate of Y (10).
3/5 of that distance = 3/5 * (10 - 1) = 7.5, which you add to the x-coordinate of X(1), to get the x-coordinate of M (8.5).
Similarly, the y-coordinate of M is 3/5 of the way between the y-coordinate of X (-2) and the y-coordinate of y (3). 5/6 of that distance = 3/5* (3 - - 2) = 4.17, which you add to the y-coordinate of X(-2), to get the y-coordinate of M(2.17).
So the coordinates of M are (8.5,2.17)
