PLEASE HELP!!!!! And explain too! Thanks!!!

I don't know any <em><u>slick</u></em> way to do this.  I would just list the prime numbers
between 40 and 50 and test them one at a time.

The prime numbers between 40 and 50 are: 41, 43, 47

<u>Test 41:</u>
-- add 1 . . . 42
-- prime factors of 42 . . . 2, 3, 7
-- sum of the factors . . . 12

<u>Test 43:</u>
-- add 1 . . . 44
-- prime factors of 44 . . . 2, 11
-- sum of the factors . . . 13

<u>Test 47:</u>
-- add 1 . . . 48
-- prime factors of 48 . . . 2, 3,
-- sum of the factors . . . 5

Maybe I'm not understanding how to list prime factors, but so far,
I haven't found any number that answers the question.

Maybe if I write the prime factorization of 44 like this:

               44 = 2 * 2 * 11

Now the items in the prime factorization do add up to 15.
So the answer would seem to be <em>43.</em>

47% of 70 estimated ????? help pleazzz
vlada-n [284]
In summary, you just multiply the percentage (move the decimal twice to the left) by the amount, which is 70 in this case.

0.47 x 70 = 32.9

Harris Interactive® conducted a poll of American adults in August of 2011 to study the use of online medical information. Of the
kirill115 [55]

Answer:

0.60 - 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.570

0.60 + 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.630

The 95% confidence interval for the true proportion would be given by (0.570;0.630) .

And if we convert this into % we got (57.0%, 63.0%)

Step-by-step explanation:

The information given we have the following info given:

n = 1019 represent the sampel size

\hat p=0.6 represent the sample proportion of interest

The confidence level is 95%, our significance level would be given by \alpha=1-0.95=0.05 and \alpha/2 =0.025. And the critical value would be given by:

z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96

The confidence interval for the mean is given by the following formula:  

\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}

Replacing the info given we got:

0.60 - 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.570

0.60 + 1.96\sqrt{\frac{0.60(1-0.60)}{1019}}=0.630

The 95% confidence interval for the true proportion would be given by (0.570;0.630) .

And if we convert this into % we got (57.0%, 63.0%)
