Answer:
11 is 150
12 is 168 lectures and 70 professers
Step-by-step explanation:
Answer: a) sample
b) quantitive.
Step-by-step explanation:
Given: A recently published research study looked at 3000 people over a period of 15 years and determined that those people who ate fast food two or more times per week had gained an average of 10 pounds more than the group who ate fast food less than twice a week.
Here, population = "people who ate fast food two or more times per week"
Since a census is the data of all members in a population whereas a sample is a subset of it.
Then, 3000 people constitute a sample as it is a subset of the population.
Since the researcher's point of interest it to measure average weight gain which is a quantitive measure.
So, the data is quantitative.
I'm not entirely positive about the answer, but I think I know what it's asking.
Least common denominator of fractions and variables such as this mean "What do both numbers have in common?"
10/3 and 1/6 can be on the same page if we multiply 10/3 by 2. This gets 20/6. 20/6 and 1/6 have a common denominator of 6, and our answer for the fraction is 1/6.
We aren't done yet. The least common denominator of the m values is just m, and same for n.
So I believe the answer is 1/6mn. I hope this helps, and I hope that I'm right about this. If you have further inquiries, don't hesitate to let me know!
