These are the elements of the matrix
Elements of the first row are h11 h12 h13, of the second row h21 h22 h23.
Than we can conclude that element h23 worth 75.
Good luck!!!
Answer:
L=3w+2...L+w=40... 4w+2=40...w=3/5 and L=30/5
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.
