Since unique combinations of students is independent of order, ie order does not matter...

n!/(k!(n-k)!), n=number of choices possible, k=number of choices made...

30!/(6!*24!)

I believe you just multiply the number of students by the number of students in each combination

30*6= 180 combinations

Which of the following choices are equivalent to the expression below? check all that apply
Naddika [18.5K]

The choices are equivalent to the expression correct choices are A, C, and D.

The given expression is

x^3 /5

<h3>What is the expression?</h3>

The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.

<h3>What is the power rule?</h3>

a^{\frac{m}{n} =\sqrt[n]{a^m}

Therefore the above power rule implies that,

x^{(\frac{3}{5}) }=\sqrt[5]{x^3}

Also, we have the power rule

(a^m)}^n=a^{mn}

x^{\frac{3}5} =(x^3)^{\frac{1}{5}

or it can be written as

x^{\frac{3}{5} =(\sqrt[5]{x})^3

The correct choices are A, C, D.

the table and grab both represent the same relationship. Which equation also represents the relationship?
Alekssandra [29.7K]

Answer:

Fourth option y = x²

Step-by-step explanation:

It is clear from the graph that parabola passes through origin, which is it's vertex and line of symmetry is y-axis.

So the equation of the parabola will be y = (x - 0)² + 0

This equation of the parabola is in the vertex form [ y = (x - h)² + k]

Therefore, equation of the parabola will be y = x²

This equation is true for the given values of x and y in the table.

For (-2, 4) ⇒ 4 = (-2)²

For (-1, 1) ⇒ 1 = (-1)²

Fourth option y = x² is the answer.
