Question

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

Answer 1

Answer:

1.5

Step-by-step 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 $1.5$

Answer 2

Answer:

1.5

Step-by-step 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
