Equality Properties

Step-by-step explanation:

<u>Step 1: Define Inequality</u>

15 < -5x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide -5 on both sides:                    -3 > x
  2. Rewrite:                                               x < -3

Here we see that any number <em>x</em> that is smaller than -3 would work as a solution to the inequality.

A jury pool consists of 50 potential jurors and how many ways can a jury of 12 be selected
bija089 [108]

Solution:

we are given that

A jury pool consists of 50 potential jurors.

Wee have been asked to find the number of ways can a jury of 12 be selected.

As we know from the concept of combination that r person can be selected out of n in ncr ways. where

n_C_r=\frac{n!}{r!(n-r)!}

Now substitute the values we get

{50}_C_{12}=\frac{50!}{12!(50-12)!}\\&#10;\\&#10;{50}_C_{12}=\frac{50!}{12!38!}\\&#10;\\&#10;{50}_C_{12}=121399651100\\

Hence the required number of ways is 121399651100

UkoKoshka [18]

Answer:

- 4\sqrt{2}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplify \sqrt{18} using this rule

\sqrt{18}

= \sqrt{9(2)}

= \sqrt{9} × \sqrt{2} = 3\sqrt{2}

Then

- 2\sqrt{18} + 2\sqrt{2}

= - 2(3\sqrt{2} ) + 2\sqrt{2}

= - 6\sqrt{2} + 2\sqrt{2}

= - 4\sqrt{2}
