Atown's population of children increased from 376 to 421 during the past year. which equation shows how to find the percent increase?

The percentage increase in the population of the chilrden since past year is .

According to the question, the town's population of children increased from 376 to 421 during the past year.

So, the increase in the population of the children is-

Now, the percentage increase in population of the children per year is calculated as-

Step-by-step explanation:

percent increase = × 100%

the increase = 421 - 376 = 45, hence

percent increase = × 100% ≈ 12%

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
