topjm [15]

Answer:

317.21 (sales price)

259.53 (discount amount)

Step-by-step explanation:

First, we need to divide.

576.75/100=5.7675 (note that I will be rounding at the end)

5.7675 x 55 (100-45) = 317.2125

Rounds to: 317.21

Now, we need to find the discount amount.

576.75

-317.21

Natasha2012 [34]

Answer: There were 469,532 American prison for drug related offenses in 2015.

Step-by-step explanation:

Since we have given that

Number of Americans in prison for drug related offenses in 1980 = 40,900

Rate of increment in Americans in prison from 1980 to 2015 = 1048%

So, Number of Americans who were in prison for drug related offenses in 2015 is given by

$\dfrac{100+1048}{100}\times 40900\\\\\dfrac{1148}{100}\times 40900\\\\=1148\times 409\\\\=469,532$

Hence, there were 469,532 American prison for drug related offenses in 2015.

How many different ways can a researcher select 4 rats from 15 rats and assign each to a different test?

Tomtit [17]

By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .

Step-by-step explanation:

We need to find How many different ways can a researcher select 4 rats from 15 rats and assign each to a different test.Let's find out:

We will use Permutation here : As we will chose 4 rats out of 15 rats , order will be considered which will make this as a permutation problem . Formula for permutation is given by :

⇒ $nP_r= \frac{n!}{(n-r)!}$

According to question , we have

⇒ $15P_4= \frac{15!}{(15-4)!}$

⇒ $15P_4= \frac{15!}{(11)!}$

⇒ $15P_4= \frac{15(14)(13)(12)11!}{(11)!}$

⇒ $15P_4= 15(14)(13)(12)$

⇒ $15P_4= 32,760$

Therefore , By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .
