A and B are correct, but A is most correct.

8 freshmen, 9 sophomores, 9 juniors, and 7 seniors are eligible to be on a committee.

loris [4]

Answer: 11113200

Step-by-step explanation:

We know that , the number of combination of choosing r things from n things is given by :-

$^nC_r=\dfrac{n!}{r!(n-r)!}$

Then , the number of ways to choose a dancing committee if it is to consist of 4 freshmen, 5 sophomores, 2 juniors, and 3 seniors :-

$^8C_4\times ^9C_5\times^9C_2\times^7C_3$

$=\dfrac{8!}{(8-4)!4!}\times\dfrac{9!}{(9-5)!5!}\times\dfrac{9!}{(9-2)!2!}\times\dfrac{7!}{3!(7-3)!}\\\\ =\dfrac{8\times7\times6\times5\times4!}{4!4!}\times\dfrac{9\times8\times7\times6\times5!}{4!5!}\times\dfrac{9\times8\times7!}{7!2!}\times\dfrac{7\times6\times5\times4!}{3!4!}\\\\=11113200$

∴ The number of ways to choose a dancing committee if it is to consist of 4 freshmen, 5 sophomores, 2 juniors, and 3 seniors = 11113200

Tony has $18 to buy apples and bananas for a fruit salad. Apples cost $2 per pound and bananas cost $1 per pound. Write and grap

nlexa [21]

The inequality to describe the situation is; 2a + 1b <= 18

Since according to the question;

Tony has $18 to buy apples and bananas for a fruit salad.

Apples cost $2 per pound and bananas cost $1 per pound.

Let the number of apples bought be; a

Let the number of bananas bought be; b

Therefore, the inequality to describe the situation is;

2a + 1b <= 18

This means that the cost of the total number of apples and bananas bought by Tony is; less or equal to $18.

Additionally, Two possible combinations of pounds and apples that Tony can buy are;

Tony buys 9 apples and no banana

Tony buys 18 bananas and no apple.
