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.
Y = 5.50x + 21...where x is the number of months and y is the total cost
function notation is basically subbing in f(x) for y
so ur rule in function notation is : f(x) = 5.50x + 21 <==
42/6=7
7-4=3.................................
