Answer:
9
Step-by-step explanation:
To solve, we can first cross multiply
28/63=4/x
28*x=63*4
28x=252
Since we are trying to find x(the missing number), we need to get x by itself. x is being multiplied by 28. To undo this, divide both sides by 28. This will cancel out 28 and leave x by itself.
28x/28=252/28
x=9
So, the missing number is 9
28/63=4/9
Answer:
The right options are C and D.
Step-by-step explanation:
One test refers to the claim that there is bias in the acceptance rate based on gender. In this case, the alternative hypothesis would claim that there is a significant difference in proportions in acceptance rate for both genders. The null hypothesis failed to be rejected, so the P-value has to be more than the significance level.
<em>C. One set of hypotheses concerns whether acceptance rates are lower (the alternative) or equivalent (the null) when the author or editor is female. The p-value for that test was apparently above 0.05.</em>
The other test is referred to the preference in gender to choose reviewers. The alternative hypothesis claim that female editors used female reviewers more often than did male editors. This has a P-value<0.001.
<em>D. One set of hypotheses concerns whether female editors chose females to review the papers less often than the alternative) or the same amount as the null) did male editors. The p-value for that test was reported to be less than 0.001.</em>

We have the identity
Take the square root of both sides and rearrange terms on the right to get
Decrementing n gives
and substituting the previous expression into this, we have
Continuing in this fashion, after k steps we would have
After a total of n - 2 steps, we arrive at
Then as n goes to infinity, the first nested radical converges to √x + 1/4. Similar reasoning can be used to show the other nested radical converges to √x - 1/4. Then the integral reduces to
