Let the total amount of pages be t
t=30+1/8t+2/8t
now simplify
t=30+3/8t
5/8t=30
divide 30 by 5
1/8=6
now you know 1/8 of the book is 6 pages which means the whole book has 48 pages.
So 10 % of 40 is 4
5% of 40 is 2
so 15% is 6
then you have to do 40-6
and then you get the answer of 34
Answer:
Sampling is necessary because researchers in the social sciences almost never have enough resources — time or money — to collect information about the entire set of subjects of interest to them.
Step-by-step explanation:
Sampling is done because you usually cannot gather data from the entire population. Even in relatively small populations, the data may be needed urgently, and including everyone in the population in your data collection may take too long.
Five-5
three-3
"the quantity five plus three" (5 + 3)
"one hundred times the quantity ..." means 100 (5 + 3)
now just solve 100(5+3)
solve the parentheses first (5+3) = 8
Now you are left with 100(8) or 100*8
when you solve your answer is 800
Hi there!
To find this you can simply use a calculator. All you have to do is divide the numerator by the denominator to see what you get.
7/200 in decimal form is 0.035. Pretty simple.
This fraction cannot be simplified.
Hope this helps!
