What is 15/4 + (−4/13) as a fraction in simplest form.

OLga [1]

Step-by-step explanation:

15/4 + (−4/13) can be rewritten as 15/4-4/13.

15/4-4/13

15 x13

4 x13

195/52

4 x4

13 x4

16/52

195/52-16/52=179/52 or 3 23/52

hope it helps!

At Appalachian State University it is known that 52% of undergraduates are female. If a sample of 150 undergraduate students was

In-s [12.5K]

Answer:

a. The sampling distribution will be approximately normal.

d. The mean of the sampling distribution will be close to 52%

g. The standard deviation of the sampling distribution will be 0.0408

Step-by-step explanation:

For this problem the sample size is large enough (n>30), and then the sampling distribution $\hat p$ would be approximately normal. The mean of the sampling distributions is given by $p=0.52$

The expected value for the sampling distribution would be 0.52 since $E(\hat p) = p$

And for the standard deviation we know that is given by:

$Sd= \sqrt{\frac{p (1-p)}{n}}=\sqrt{\frac{0.52(1-0.52)}{150}}=0.0408$

So the correct answers on this case are:

a. The sampling distribution will be approximately normal.

d. The mean of the sampling distribution will be close to 52%

g. The standard deviation of the sampling distribution will be 0.0408

Angelina factored (x - 48 ) and wrote that it was equal to (x^2 - 4^2)^2(x^2 + 4^2). Use complete sentences to explain how you c

defon

(x^2 - 4^2)^2 = x^4 - 4^4
(x^4 - 4^4) (x^2 + 4^2) = x^2 - 4^6
The Angela's solution is wrong cause when you multiply you get a different answer.
