Answer: 14p +70
Step-by-step explanation:
Nathaniel is correct. fractions are rational numbers
we have the data set
3,1,7,0,4
step 1
Find out the sample mean
sample mean=(3+1+7+0+4)/5
sample mean=15/5
sa,ple mean=3
step 2
Complete the table
x (x-mean) (x-mean)^2 x^2
3 (3-3) (3-3)^2 0
1 (1-3) (1-3)^2 4
7 (7-3) (7-3)^2 16
0 (0-3) (0-3)^2 9
4 (4-3) (4-3)^2 1
