To determine the number of rabbits in the forest the ranger tags 100 and releases them back into the forest. Later, 350 of rabbits are caught out of which 40 were tagged. What is the estimated number of rabbits in the forest?

875

Step-by-step explanation:

If there are 100 tagged rabbits and which there are 40 tagged out of 350 we get

The amount tagged/ The amount of rabbits = Tagged come back/Caught

If we replace the equations we get the equation

100/x = 40/350

Step 1. Cross Multiply

40x = 35000

x = 875

There are 875 rabbits

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.
