The angles of a triangle always add up to 180°.

120 + x + 16 + x = 180

Add up the values.

136 + 2x = 180

Subtract 136 from both sides.

2x = 44

Divide both sides by 2.

x = 22

In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed. Use

Answer:

Claim is true that most medical malpractice lawsuits are dropped or dismissed.

Step-by-step explanation:

Given :In a study of 799 randomly selected medical malpractice lawsuits, it was found that 499 of them were dropped or dismissed.

To Find : Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

Solution:

n = 799

x = 499

We will use one sample proportion test

$\widehat{p}=\frac{x}{n}\\\widehat{p}=\frac{499 }{ 799}\\\widehat{p}=0.6245$

We are given that the claim is most medical malpractice lawsuits are dropped or dismissed.

Probability of dropped or dismissed is 1/2

$H_0:p=0.5\\H_a:p>0.5$

Formula of test statistic = $\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

= $\frac{0.6245-0.5}{\sqrt{\frac{0.5(1-0.5)}{799}}}$

= 7.038

p value (z>7.038) is 0

α =0.05

So, p value < α

So, we reject the null hypothesis

So,claim is true

Hence most medical malpractice lawsuits are dropped or dismissed.

Write the equation in point slope form for a line that passes through the points (-2,3) and (6,-1)

diamong [38]

Answer:

y - 3 = -1/2(x + 2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

<u>Algebra I</u>

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

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate

y₁ - y coordinate

m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-2, 3)

Point (6, -1)

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

Substitute: $m=\frac{-1-3}{6+2}$
Subtract/Add: $m=\frac{-4}{8}$
Simplify: $m=\frac{-1}{2}$

<u>Step 3: Write linear equation</u>

Point-Slope Form: y - 3 = -1/2(x + 2)
