ASHA 777 [7]

Answer:

3003

Step-by-step explanation:

We want to find out how many ways we can choose 10 players among 15 players (since the goalie is not interchangeable)

The number of different lineups you can have can be found by using combination:

$^{15}C_{10} = \frac{15!}{(15 - 10)! 10!}\\ \\= \frac{15!}{5! * 10!} \\\\= 3003$

There are 3003 different lineups that can be chosen.

What is 36x^9y^4/4x^7y^3

motikmotik

Get rid of all common factors.
36/4 = 9
x^9/x^7 = x^2
y^4/y^3 = y

$\boxed{\frac{36x^9y^4}{4x^7y^3}=9x^2y}$

Which of the following statements is true?

Vitek1552 [10]

Answer:

Step-by-step explanation:

1/9 can be simplified to 1/3 as 1/3 x 1/3 = 1/9 and 49/25 can be simplified to 7/5 as 7/5 x 7/5 = 49/25.

Now looking at both the fraction 1/3 and 7/5

1/3 simplifies to 0.34

It is an irrational value as the 3 keeps repeating.

7/5 simplifies to 1.4

It is a rational value as the decimal value is not repeating.

Thus making the second option the answer.
