For the reciprocal, you swap numerator and denominator.

a. The reciprocal of \frac{\sqrt{2}}{2} is \frac{2}{\sqrt{2}}
To rationalize the irrational denominator, multiply numerator and denominator by the radical, then simplify.
=\frac{2 \times \sqrt{2}}{\sqrt{2} \times \sqrt{2}} = \frac{2 \sqrt{2}}{2} = \sqrt{2}

b. \frac{-2}{\sqrt{3}} = \frac{-2 \sqrt{3}}{3}

A bag contains 6 red marbles, 3 blue marbles and 8 green marbles. If three marbles are drawn out of the bag, what is the probabi
ale4655 [162]

This is a 4 step problem.

Find the probability of drawing a green marble the first time

<em>8 green marbles ÷ 17 total marbles </em>

Next, we find the probability of drawing a green marble the second time

<em>7 green marbles ÷ 16 total marbles </em>

Find the probability of drawing a green marble the third time

<em>6 green marbles ÷ 15 total marbles </em>

We<u> take away one</u> from the total marbles and green marbles each time because we are finding the probability that we draw a green marble <u>all three times </u>

Last step:

Multiply all the probabilities

\frac{8}{17} × \frac{7}{16} × \frac{6}{15}

The final answer is 7/85 or an 8% chance

If you were curious, the decimal version of this answer is <u>0.08235294</u>

What is the slope of the line that passes through the points (3, 2) and (-1,2)?
Usimov [2.4K]

Answer:

The slope is 0.

Step-by-step explanation:

slope formula: \frac{y2-y1}{x2-x1}

Given points: (-1, 2), (3, 2)

(-1, 2) = (x1, y1)

(3, 2) = (x2, y2)

To find the slope, input the given points into the formula used to find slope:

\frac{2-2}{3-(-1)}

Simplify:

2 - 2 = 0

3 - (-1) = 3 + 1 = 4

\frac{0}{4} = 0

The slope is 0.

Hope this helps :)
