Answer 1

Average number in a month = 46

Average number in a day = 1.5

Explanation:

Given that:

Scientific Dr. Sparks has counted the flashes of lightning around his home for a period of 3 months.

Number of sparks counted in June = 25

Number of sparks counted in July = 51

Number of sparks counted in August = 62

To find:

Average number in a month ?

Average number in a day ?

Solution:

Average of observations can be defined as the ratio of total sum of all the observations to the total number of observations.

`Average = \frac{\text{Sum of all observations}}{\text{Total number of observations}}`

Average as per month =
`(25+51+62)/(3) =(138)/(3) = 46`

To find the average number in a day, we need to first find the number of days.

Number of days in June = 30

Number of days in July = 31

Number of days in August = 31

Total number of days = 92

Average as per month =
`(25+51+62)/(92) =(138)/(92) = 1.5`
