Answer from top to bottom: radical 17, pie, 3.01245, and at the bottom radical 8 over 3
Ten (10) times (multiplication) the sum (addition) of half (
a number (n) and 6 is (=) 8.
10(
+ 6) = 8 Use the Distributive Property
5n + 60 = 8 Subtract 60 from both sides
5n = -52 Divide both sides by 5
n = -10 
3.14 is the answer correct
Which sampling method divides the population up into sections, randomly selects some of those sections, then chooses all the members from the selected sections to study?
Answer: The above mentioned type of sampling is called cluster sampling.
Cluster sampling is a sampling technique in which the entire population of interest is divided into clusters or groups, then the investigator randomly selects some of these clusters and all the members of these randomly selected clusters are investigated.
Answer:
.25 .75
.44 .56
Step-by-step explanation:
To find the relative frequency, we take the part over the total.
Since this is a relative frequency table, the total for each row is 1
Group 1 A = 15/ (15+45) = 15/60 = .25
Group 1 B = 45/(15+45) = 45/60 = .75
Group 2 A = 20 /(20+25) = 20/45 =.44
Group 2B = 25/(20+25) = 25/45 =.56
