Step-by-step explanation:
When you say a random sample, this means that every member of the population will have a chance to be part of the sample. If you consider the scenarios, only the 1st and 3rd option will come up with a random sample because the respondents of the sample is not predetermined. If you take the other options into consideration, you can see that not everyone would have had a chance to be part of the sample.
Normally when you're gathering sources it depends on what the topic is, what time or day, you try to find facts, and you see if there are any other useful information.
Answer:
y=2
Step-by-step explanation:
Essentially we must find a height such that 70:height is at the same ratio as 16:9. So
16/9=70/h
1.778=70/h
1.778h=70
h=70/1.778=39.37inches
Check work:
16:9 = 1.7777778
70:39.37 = 1.778
