The stem and leaf plot represent the list of numbers:
- 15, 18, 46, 50, 50, 50, 50, 57
The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values.
The formula for the mean of a population is
The formula for the mean of a sample is
Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values entered above, the solution is:
Answer:
Step-by-step explanation:
Given:
Slope of line =-5
y-intercept =
The equation of line is given by :
where represents slope of line and
represents y-intercept.
So from the given data, we have and
∴ The equation of line is given by:
