Help please? (it’s y=mx+b stuff)

Gelneren [198K]

Answer:

5. C

6. A

Step-by-step explanation:

To find the answer, plug in the x- and y-values into each equation. When the equation comes to be true that is your answer.

So for question 5, you plug -5 into the x and 13 into the y for each equation. The first equation will give you an answer of 13 = -7, which isn't true.

The second will give you 13 = 7, so you keep going.

The third gives you 13 = 13, which is true, so that one must be the answer.

Do this for every question and it will give you the answer.

Suppose 241 subjects are treated with a drug that is used to treat pain and 54 of them developed nausea. Use a 0.05 significance

lana66690 [7]

Answer:

Null Hypothesis, $H_0$ : p = 0.20

Alternate Hypothesis, $H_a$ : p > 0.20

Step-by-step explanation:

We are given that 241 subjects are treated with a drug that is used to treat pain and 54 of them developed nausea.

We have to use a 0.05 significance level to test the claim that more than 20% of users develop nausea.

Let p = population proportion of users who develop nausea

So, Null Hypothesis, $H_0$ : p = 0.20

Alternate Hypothesis, $H_a$ : p > 0.20

Here, null hypothesis states that 20% of users develop nausea.

And alternate hypothesis states that more than 20% of users develop nausea.

The test statistics that would be used here is One-sample z proportion test statistics.

T.S. = $\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }$ ~ N(0,1)

where, $\hat p$ = proportion of users who develop nausea in a sample of 241 subjects = $\frac{54}{241}$

n = sample of subjects = 241

So, the above hypothesis would be appropriate to conduct the test.

X - 5(x + 1) = 3x + 2 answer , but show work pls.

Nitella [24]

Answer: x = -1

Step-by-step explanation:

Starting:

x-5(x+1)=3x+2

Simplify the left side:

-4x-5=3x+2

Move all the terms with an x to the left:

-7x-5=2

Move all the terms without an x to the right:

-7x=7

Divide both sides by -7:

x = -1

- Higher Order Thinking A rectangular poster has

DaniilM [7]

Answer: 36 centimeters.

Step-by-step explanation:

Given : Area of a rectangular poster = 504 square centimeters.

The width of the poster is 14 centimeters.

We know that area of rectangle :-

$\text{Area= length x width }$

Let l be the length of the poster .

Substitute the above values into this , we get

$504=\text{l}\times 14$

i.e. $504=14\text{l}$

Divide both sides bby 14 , we get

$l=36$

Hence, the length of the poster = 36 centimeters.
