Question

Annabelle measured and recorded the amount of rainfall for 9 days in a row. Her results are shown below. 3/10in., 1/5in.,1/10in., 3/10in., 2/5in., 1/5in., 1/5in., 1:5in. What is the average amount of rainfall per day for the 9-day period?

Answer 1

Answer:

Therefore,  the average amount of rainfall per day for the 8-day period is 0.2375in.

Step-by-step explanation:

We know that Annabelle measured and recorded the amount of rainfall for 9 days in a row. Her results are shown below. 3/10in., 1/5in.,1/10in., 3/10in., 2/5in., 1/5in., 1/5in., 1:5in.

We have 8 values given. So we will calculate the average value in 8 days.

We have

3/10+1/5+1/10+3/10+2/5+1/5+1/5+1/5=19/10

we get

$\frac{19/10}{8}=0.2375$

Therefore,  the average amount of rainfall per day for the 8-day period is 0.2375in.
