Arte-miy333 [17]

Answer: 0.22

Step-by-step explanation:

We know that the best point estimate for the difference between two population mean is the difference between their sample means.

Given : For the 39 randomly selected upperclassmen, the sample mean was 0.12 and sample standard deviation was 0.42. For the 35 randomly selected underclassmen, the sample mean was 0.34 and the sample standard deviation was 0.87.

Let A denotes the population of upperclassmen and B denotes the population of underclassmen .

\overline{x}_A=0.12

\overline{x}_B=0.34

Then, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen will be :-

\overline{x}_B-\overline{x}_A=0.34-0.12=0.22

Hence, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen =0.22

Mrs O’maley ran 2 2/3 miles today.she plans to run the same distance every day this week. How many total miles wil she run this
natulia [17]
Okay, so we multiply..

And we know that a week = 7 days..

So..

2 * 2/3 * 7 = ???

We change the 2 into 2/1
THEN we multiply..

2/1 * 2/3 = 4/3

Then we change the 7 into 1/7.. ( Which is still a whole )

Then multiply again..

4/3 * 1/7 = 4/21

You can correct me if I'm wrong...
I hope this helps you!

Given: sin = 4/5 and cos x = -5/13 ; evaluate the following expression. Cos 2x
Nitella [24]

For every possible angle x, the fundamental law of trigonometric states that

\sin^2(x)+\cos^2(x) = 1

In your case, the inputs you provided would lead to

\dfrac{16}{25}+\dfrac{25}{169} = \dfrac{3329}{4225} \approx 0.8 \neq 1

So, it is not possible that, for a certain angle x, we have

\sin(x) = \dfrac{4}{5},\quad \cos(x) = -\dfrac{5}{13}
