Is choosing 5 players to represent the team at a fundraiser a permutation or a combination?

1 answer:

3 0

A permutation, since once you choose one member to be in the team, that same person cannot be chosen again. A combination requires us to be able to freely choose the same item in a set as many times as we may wish. A permutation restricts the amount of times we can choose an item in a set.

Rewrite in simplest radical form: x^4/5 / x^1/3 into a√x^b

mrs_skeptik [129]

Answer:

$\sqrt[15]{x^7}$

Step-by-step explanation:

If we have the expression

$\frac{x^{\frac{4}{5}}}{x^{\frac{1}{3}}}$ , we have to think about exponent rules.

If we have $a^b \div a^c$ , then the value will be equal to $a^{b-c}$ .

So $\frac{x^{\frac{4}{5}}}{x^{\frac{1}{3}}}$ simplified will be $x^{\frac{4}{5} - \frac{1}{3}}$

Converting $\frac{4}{5}$ and $\frac{1}{3}$ into fifteenths (lcm) gets us $\frac{12}{15} - \frac{5}{15} = \frac{7}{15}$ .

We can convert $x^{\frac{7}{15}}$ into a radical by taking the denominator root of x to the numerator.

$\sqrt[15]{x^7}$ .

Hope this helped!

Drag and drop each pair of lines to categorize them as either parallel, perpendicular, or neither.

miss Akunina [59]

Answer:
first box is parallel
Second box perpendicular
Third box neither
Fourth box neither
Fifth box perpendicular
Sixth box is parallel

Why? Slopes of parallel lines are the same. Slopes of perpendicular lines are opposite reciprocals. (Example slope=1/2 a perpendicular line would be -2/1). Neither is just a when it’s not either parallel or perpendicular.

Hope this helps
