Please answer the question!

Step-by-step explanation:

Here, we will have to use or, least common denominator.

The least common here that we will be using is going to be 30. We can always make sure by multiplying.

*

Our final answer for the first fraction is which could be simplified back to .

For the second fraction, we will be multiplying with .

*.

Again, it simplifies back to .

Hence, the is .

Hope that helps:D

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.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
