Answer:
To select a <u>stratified</u> random sample, first classify the population into groups of similar individuals, then choose a separate SRS in each group and combine these SRS to form the full sample
Step-by-step explanation:
Stratified random sampling involved dividing the population into small groups of similar individuals (called strata) and then from among those groups, a stratified random sample is selected and then, all these samples are combined to form the full sample. Hence, the missing word in this sentence is <u>stratified.</u>
3 pen + 2 pencil = .47
2 pen + 3 pencil = .38
2(3pen + 2 pencil = .47)
-3(2pen + 3 pencil = .38)
6 pen + 4 pencil = .94
-6 pen - 9 pencil = -1.14
- 5 pencil = -.2
pencil = .04
3pen + 2(.04) = .47
3pen + .08 = .47
3 pen + .08 - .08 = .47 -.08
3 pen = .39
pen = .13
Pen = 13 cents and pencil = 4 cents
