The equivalent expression of \frac{3x}{x + 1} \div x + 1 is \frac{3x}{(x + 1)^2} or \frac{3x}{x^2 +2x + 1}

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

\frac{3x}{x + 1} \div x + 1

Rewrite the expression as a product

\frac{3x}{x + 1} \times \frac{1}{x + 1}

Evaluate

\frac{3x}{(x + 1)^2}

Expand

\frac{3x}{x^2 +2x + 1}

Hence, the equivalent expression of \frac{3x}{x + 1} \div x + 1 is \frac{3x}{(x + 1)^2} or \frac{3x}{x^2 +2x + 1}

Find the slope using the formula.<br> (3,-2) and (3, 6)
dangina [55]

Answer:

m = undef

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (3, -2)

Point (3, 6)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{6+2}{3-3}
  2. Add/Subtract:               m=\frac{8}{0}
  3. Divide:                          m = undef

When we divide anything by zero, we will get undefined. Therefore, this would be a vertical line.

In the United States, 75 percent of adults wear glasses or contact lenses. A random sample of 10 adults in the United States wil
V125BC [204]

Answer:

0.4745 is the probability that fewer than 8 of the selected adults wear glasses or contact lenses.

Step-by-step explanation:

We are given the following information:

We treat adult adults wear glasses or contact lenses as a success.

P(Adults wear glasses or contact lenses) = 75% = 0.75

Then the number of adults follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 10

We have to evaluate:

P(fewer than 8 of the selected adults wear glasses or contact lenses)

P(x < 8)\\=1 - P(x = 8) - P(x = 9) - P(x = 10)\\=1 - \binom{10}{8}(0.75)^8(1-0.75)^2 - \binom{10}{9}(0.75)^9(1-0.75)^1- \binom{10}{10}(0.75)^10(1-0.75)^0\\=1 - 0.2815-0.1877-0.0563\\= 0.4745

0.4745 is the probability that fewer than 8 of the selected adults wear glasses or contact lenses.
