zhuklara [117]

Answer:

The probability of all chosen be the best:

$\frac{\frac{8\cdot 7\cdot 6}{3!}}{\frac{27\cdot 26\cdot 25}{3!}}=\frac{8\cdot 7\cdot 6}{27\cdot 26\cdot 25}$

$=\frac{56}{2952}$

To determine:

Step-by-step explanation:

If you choose to read 3 of them randomly, what is the probability all 3 chosen are best sellers?

Information Fetching and Solution Steps:

A single shelf holds 27 books.

On one particular shelf, 8 books are best sellers.
We have to choose to read 3 of them randomly

The formula to find the number of possible combinations

of 3 books from 27 books where order doesn't matter

$C\left(n,k\right)=\frac{n!}{k!\left(n-k\right)!}$

So,

$\:\:C\left(27,\:3\right)=\frac{27!}{3!\left(27-3\right)!}$

$=\frac{27!}{3!24!}$

$=\frac{27\cdot 26\cdot 25}{3!}$

And

The formula for the number of combinations of 3 vest sellers from 8 books will be:

$C\left(8,\:3\right)=\frac{8!}{3!\left(8-3\right)!}$

$=\frac{8!}{3!5!}$

$=\frac{8\cdot 7\cdot 6}{3!}$

So, the probability of all chosen be the best:

$\frac{\frac{8\cdot 7\cdot 6}{3!}}{\frac{27\cdot 26\cdot 25}{3!}}=\frac{8\cdot 7\cdot 6}{27\cdot 26\cdot 25}$

$=\frac{56}{2952}$

The length of a rectangle is seven more than double the width. If the perimeter is 22 inches find the dimensions

lubasha [3.4K]

Answer:

width = 1 1/3 inches

length = 9 2/3 inches

Step-by-step explanation:

let 'w' = width

let '7+2w' = length

P = 2l + 2w

22 = 2w + 2(7+2w)

22 = 2w + 14 + 4w

8 = 6w

w = 4/3 or 1 1/3

substitute 1 1/3, or 4/3, to find length:

l = 7 + 2(4/3)

l = 7 + 8/3 or 9 2/3

Use the Distributive Property to write an expression that is<br> equivalent to 4(y - 3).

Nonamiya [84]

Answer:

4y-12

Step-by-step explanation:

To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).

If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.
