Pls explain with proper steps

1. A farmer moves along the boundary of a square field of side 10m in 40s. What will be the
magnitude of displacement of the farmer at the end of 2 minutes 20 seconds?
2. What is the acceleration of a body moving with constant velocity?
3. Is it possible for a body to be accelerated, if its speed is constant. If so, give an example.

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.

can you make your screen more see able?

then i might be able to .

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
