Given :7872 ÷ 305.

Because it's estimation. So, we need to estimate the number 7872 to 8000.

In order to divide 8000 by a number we need to estimate 305 to the 400. Because 400 is exact divisor of 8000.

If we divide 8000 by 400 we get 20.

And it's obviously less then 60000 ÷ 300= = 200.

20 < 200.

<h3>Therefore, Harrison is absolutely correct.</h3>

Ksju [112]

A total of 1,716 selections of the 7 flowers are possible.

Step-by-step explanation:

Step 1:

There are 13 flowers from which Jeanine Baker plans to use 7 of them.

To determine the number of selections that are possible we use combinations.

The formula for combinations is; $^{n} C_{r}=\frac{n !}{(n-r) ! r !}$ .

Step 2:

In the given formula, n is the total number of options and r is the number of options to be selected.

For this question, $n = 13$ and $r=7$ .

So $^{13} C_{7}=\frac{13 !}{(13-7) ! 7 !} = \frac{13 !}{(6) ! 7 !} = 1,716.$

So a total of 1,716 selections are possible.
