candace help out at the library after school. The head librarian tells her that there are 2,160 books in the children's section

Slav-nsk [51]

That would be 40 books on each shelf. Hope that helped :)
Here is the process:
2,160/ 9 stands = 240 books per stand
240 stands/ 6 shelves each = 40 books on each shelf.

Is it congruent SSS or Congruent ASA

It wouldn’t be SSS cause not all of the sides are the same so congruent asa?

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.

which of the following is the correct graph of the compound inequality 4p + 1> -7 and 6p + 3 < 33 ?

PtichkaEL [24]

<h3>Answer: Choice C</h3>

============================================================

Explanation:

Let's solve the first inequality for p

4p+1 > -7

4p > -7-1

4p > -8

p > -8/4

p > -2

And we'll do the same for the second inequality as well

6p+3 < 33

6p < 33-3

6p < 30

p < 30/6

p < 5

----------------------

We've found that p > -2 and p < 5

This must mean -2 < p < 5

The graph of which consists of open holes at -2 and 5 on the number line, then we shade in between those open holes. The open holes are to indicate "do not include the endpoint as part of the shaded solution set".

We can say that p is between -2 and 5, excluding both endpoints.

So that's why graph C is the final answer.
