There are some pencils and erasers in a box. If there are 12 pencils and the ratio
of pencils to erasers is 3:2, how many
erasers are in the box?

There are 8 erasers in the box

Step-by-step explanation:

given that the Ratio of pencils to erasers is  3:2

No matter how many pencils and erasers are there the ratio will simplify to the given ratio.

Let x be the number of erasers when there are 12 pencils

The ratio of 12 pencils to x erasers will be same 3:2

Putting it mathematically

Hence,

There are 8 erasers in the box

two data sets with the same median will not have the same varaibility

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
