D but im not sure if im right
Answer:
Melinda's statement is true.
Step-by-step explanation:
Division implies determination of the number of times that a given number would divide another given number. Example, dividing 100 by 20 means that how many 20s can we get from 100.
Melinda dividing 500 by 50 is trying to determine how many 50s can be found in 500. So that this gives 10.
i.e 
= 10
Therefore, 50 would go in 500 in 10 times. Melinda's statement is true.
For a 99% confidence interval for
μ based on a simple random sample.
Part (a):
Is it correct to say that
the probability that μ is in the specified interval is 99%?
Explain.
No. The probability that μ falls inside the interval is 0 or 1.
Rather we say that we are 99% confident that μ will fall inside the interval.
Part B:
Is it correct to say that in the long run, if you computed many,
many confidence intervals using the prescribed method, about 99% of
such intervals would contain μ?
Yes. 99% of intervals constructed using this method will capture
the population mean μ.

Step-by-step explanation:
2.) Given: There are 30 students. 24 are wearing sneakers.
Work: We can figure this out by finding the exact percentage of sneaker-wearers in the class.
To find the percentage, you do 24/30. 24/30 is equal to 80%.
Answer: Joe is wrong. The percentage of students wearing sneakers is 80% and not 70%.
3.) Given: There are 40 people total. 2 women per 3 men.
Work: 2:3 women to men
If we multiply both by 10, we will get 50 people in total.
20:30 = 50
So we need to shrivel this down to 40 by taking out 5 on both sides of the ratio.
50 - 5 - 5 = 15:25 = 40
But the ratio need to be divisible by 2 because of the 2 women that are needed per 3 men. We can do this by moving over one human to the men’s side.
There are 14 women and 26 men. I didn’t use any of the strategies there listed because I don’t even remember what those are. I’m in grade 9. I would say that the ratio table works best because I just used ratios...
4.) Given: Find simplified fraction of silicon. 100%.
Work: Add all things up to find out the denominator for the fraction. They will equal 100.
So the fraction is 28/100.
We can divide this fraction by 4.
7/25
This is the simplified form.
Answer: 7/25
