Which table represents the equation y = -2x + 17?

Alexeev081 [22]

<h3>Answer: Choice A</h3>

Explanation:

Each table has x = 10 in it. Plug this value into the given equation.

y = -2x+17

y = -2*10+17

y = -20+17

y = -3

The input x = 10 leads to the output y = -3. Table A shows this in the middle-most row. So that's why choice A is the answer. The other tables have x = 10 lead to y values that aren't -3 (eg: choice D has x = 10 lead to y = 12), so we can rule them out.

Mademuasel [1]

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.

Solve the equation <br> (If possible please show work)

deff fn [24]

Answer:

$x=-3$

Step-by-step explanation:

So we have the equation:

$-2(-x-4)+3=-7-4x$

First, distribute the left side:

$-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x$

Add values on the left side:

$2x+11=-7-4x$

Add 7 to both sides. The right side cancels:

$(2x+11)+7=(-7-4x)+7\\2x+18=-4x$

Subtract 2x from both sides. The left side cancels:

$(2x+18)-2x=(-4x)-2x\\18=-6x$

Divide both sides by -6:

$(-6x)/-6=18/-6\\x=-3$

Therefore, x equals -3.

4x-4>20

Step 1: Add four to both sides
4x-4+4>20+4
4x>24
Step 2: Divide both sides by 4
4x divided by 4 and 24 divided by 4
Answer: x>6
Kahal accidentally subtracted instead of adding. He made a mistake in step 2.
