<h3><u>Cookies</u></h3>

Rob: 3

Barry: 8

Kevin: 9

Let's add all of that up.

3 + 8 + 9

11 + 9

= 20 cookies total


<h3><u>Milk</u></h3>

Rob: 2

Barry: 1

Kevin: 4

Let's add this up.

2 + 1 + 4

3 + 4

= 7 cups of milk


They had 20 cookies and 7 cups of milk before they ate.

9. Write an equation parallel to y = 2x + 4that<br> passes through the point (-4,-1).
sasho [114]

Answer:y=2x+7

Step-by-step explanation:

so for the new equation, we know the slope is going to be the same (because its parallel) so for starters we have y=2x+b so now in order to find b (the y-intercept) we have to plug the point into the equation. So it would look like -1=2(-4)+b and then you solve for b and get 7 for b. SO the final answer is y=2x+7.

In the United States, 36 percent of the people have a blood type that is A positive. From a random sample of 150 people from Nor
djverab [1.8K]

Answer:

The standard deviation used in the test statistic is 0.04.

Step-by-step explanation:

A single proportion <em>z</em>-test can be used to determine whether the proportion of people in Norway with a blood type of A positive is different from that in the United States.

The proportion of people in Norway with a blood type of A positive is 36% or 0.36.

The hypothesis can be defined as:

<em>H₀</em>: The proportion of people in Norway with a blood type of A positive is 36%, i.e. <em>p</em> = 0.36.

<em>Hₐ</em>: The proportion of people in Norway with a blood type of A positive is different from 36%, i.e. <em>p</em> ≠ 0.36.

The test statistic is:

z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}

The information provided is:

<em>p</em> = 0.36

<em>n</em>  = 150

Compute the standard deviation used in the test statistic as follows:

\sigma=\sqrt{\frac{p(1-p)}{n}}

   =\sqrt{\frac{0.36\times (1-0.36)}{150}}

   =\sqrt{0.001536}\\=0.03919184\\\approx 0.04

Thus, the standard deviation used in the test statistic is 0.04.
