From the first inequality x > 2 - 3 so x> -1
and from the second:- x <= 4
so the graph will be a number line with an open circle at x = -1 and a closed circle at x = 4 and the line is shaded in between.
Coefficient of variation is calculated by dividing the standard deviation by the mean multiplied by 100. Given a data set with mean equal to 60 and variance equal to 9, we can calculate the coefficient of variation by finding the value of the standard deviation which is the square root of the variance. so standard deviation is equal to square root of 9 which is 3. Then, the coefficient of variation is equal to 3/60*100 which is equal to 5%.
