The sum of two numbers is 25. The difference between twice the first number and the second number is -10. Find the numbers

The five most important sample values are sample minimum, sample maximum, median, lower quartile, and upper quartile.

Min=−10

Max=25

M=7.5

Q1=−10

Q3=25

Step-by-step explanation:

The five-number summary is a descriptive statistic that provides information about a set of observations. It consists of the following statistics:

1. Minimum (Min) - the smallest observation

2. Maximum (Max) - the largest observation

3. Median M - the middle term

4. First Quartile Q1 - the middle term of values below the median

5. Third Quartile Q3 - the middle term of values above the median

Arrange the terms in ascending order.

−10,25

The minimum value is the smallest value in the arranged data set.

−10

The maximum value is the largest value in the arranged data set.

25

Find the median.

7.5

The lower half of data is the set below the median.

−10

The upper half of data is the set above the median.
