Q. # 15 please help to solve

1 answer:

5 0

Since
$18x^3=2\cdot 3\cdot 3\cdot x\cdot x\cdot x \\ \\ 30x^5=2\cdot 3\cdot 5\cdot x\cdot x\cdot x\cdot x\cdot x$
you can see that common expression is
$2\cdot 3\cdot x\cdot x\cdot x=6x^3$ .
Answer: Correct choice is A.

Anita plans to give her husband 3 shirts for his birthday. She narrows the search to 3 shirts from a selection of 17 shirts at D

Lunna [17]

Using the combination formula, it is found that she can select the shirts in 775,200 ways.

The order in which the shirt are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.

Combination formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

3 shirts from a set of 17.

Then, 3 shirts from a set of 20.

They are independent, hence, to find the total, we multiply both combinations.

$T = C_{17,3} \times C_{20,3} = \frac{17!}{3!14!} \times \frac{20!}{3!17!} = 680 \times 1140 = 775200$

She can select the shirts in 775,200 ways.
