Answer:
Option A
Step-by-step explanation:
Given is a scatter plot graph with so many points marked on it and the least possible regression line is drawn with least distance from the points.
We are to find the equation of the line of best fit.
On the x axis is marked minutes played and y axis points scored.
To find the equation of the regression line we must have atleast two points lying on it.
We find that two points lying on it are (30,21) and (8,6)
Slope of the line = change in y / change in x
=
Using point slope formula we find that
Option A is right answer

The relative frequency for the third class, 60 - 69 is equal to 12%.
<h3>What is a class width?</h3>In a frequency distribution table, a class width can be defined as the difference between the upper (maximum) and lower (minimum) boundaries of any class in a data set. This ultimately implies that, all classes must all have the same width in a frequency distribution table.
<h3>What is a frequency table?</h3>A frequency table can be used to graphically represent the frequencies or relative frequencies that are associated with a categorical variable.
<h3>How to calculate the relative frequency for the third class, 60 - 69?</h3>First of all, we would determine the total number of frequency as follows:
Total frequency = 12 + 11 + 6 + 10 + 11
Total frequency = 50.
Mathematically, relative frequency can be calculated by using this formula:
Relative frequency = class frequency/total frequency × 100
Relative frequency = 6/50 × 100
Relative frequency = 0.12 × 100
Relative frequency = 12%.
