A. Greater than
B. Less than
C. Equal to
Answers
now, an OCTAgon, has OCTA=8, sides
an HEXAgon, has HEXA=6, sides
check what their external angles are, and compare :)

Publishing scientific papers online is fast, and the papers can be long. Publishing in a paper journal means that the paper will live forever in libraries. The British Medical Journal combines the two; it prints short and reasonable versions, with longer versions available online. Is this OK with authors? The journal asked about a random sample of 104 of its recent authors' several questions. One question was, "Should the journal continue using this system?"In the sample, 72 said "yes." (a) do the data give good evidence that more than two-thirds (67%) of authors support continuing this system? carry out an appropriate test to help answer this question. (b) interpret the p-values from your test in the context of the problem.

What is Normal Distribution?
Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Given that, Mrs. smith reading class can read a mean of 175 words per minute with a standard deviation of 20 words per minute. The top 3% of the class is to receive a special award. we need to find the minimum number of words per minute a student would have to read in order to get the award.
The z-value separating the top 3% of a normal population from
the bottom 97%.
That value is z = 1.8808
The associated raw score value using x = zs + u
x = 1.8808*20 + 175
x = 212.62
213 is the minimum number of words per minute.
Hence 213 is the minimum number of words per minute a student would need to read in order to get the award.

Solution 1 : 10mL with 20% acid
Solution 2 : 30mL with x% acid
Solution 3 : 40mL with 32% acid
Since solution 1 + solution 2 = solution 3, let us substitute the given values we have:
10(0.2) + 30(x) = 40(0.32)
2 + 30x = 12.8
To solve for the unknown concentration x, we subtract 2 from both sides:
2 + 30x - 2 = 12.8 - 2
30x = 10.8
Dividing both sides by 30:
30x/30 = 10.8/30
x = 0.36
Therefore the unknown solution is 36% acid.
Answer:
Therefore the unknown solution is 36% acid.
