The mean decreases, think about it, if every single value in a data set was decreased by the same number, the average would also go down by the same number

The median would also go down, because the value in the middle of the data set would now be smaller than before

The mode would also decrease, because the value that showed up the most in the data set has now also been decreased

The range, however, stays the same. If the lowest value in a data set was 3 and the highest was 10 and you subtracted 2 from each value in the data set, you would have the lowest at 1 and the highest at 8. But, 10-3 still equals 8-1, so the range is unchanged

A CHICKEN COOP HOLDS A TOTAL OF 10 HENS OR 20 CHICKS. IF 2/5THS OF THE HENS IN A FULL COOP ARE REMOVED, HOW MANY NEW CHICKS COUL

LiRa [457]

Answer:

8 new chicks can be fitted in the coop.

Step-by-step explanation:

A chicken coop holds 10 hens or 20 chicks.

That means space in the coop for 10 hens = space for 20 chicks

Or space for 1 hen = space for 2 chicks

Now $\frac{2}{5}$ th of the hens were removed from the coop.

So, number of hens removed from the coop = $\frac{2}{5}\times 10$

= 4 hens

And space for 4 hens in the coop = space for the 8 chicks

Therefore, 8 new chicks can be fitted in the coop.
