Question

Find the mean of 1.8,1.7,1.3,1.1,1.2,1.6,1.8

Answer 1

1.5

Explanation:

mean=sum of the terms/no of terms

mean= 1.8+1.7+1.3+1.1+1.2+1.6+1.8 /7

mean=10.5/7

to remove the decimal point, multiply 10 in both numerator and denominator since there is one digit after the decimal point in 10.5

mean=10.5×10/7×10

mean=105/70

mean=3/2

mean=1.5

hope it helps you!

Answer 2

1.5

Explanation:

To find the mean, we must add all of our terms, and then divide by the number of terms.

`1.8+1.7+1.3+1.1+1.2+1.6+1.8`

Solve:

`1.8+1.7+1.3+1.1+1.2+1.6+1.8=10.5`

Since we have seven terms, we must divide our total (
`10.5`), by seven.

`10.5` ÷
`7`

Solve:

`10.5` ÷
`7=1.5`

Therefore, the mean is
`1.5`
