I believe the answer is 2
With only the description, my answer is 20 students.
It can't be A. since if you only look at managers, you are missing all the sales executives.
It may be C. this option is more random but doesn't guarantee that you will represent both groups of employee's. Also, each time you would conduct the survey, you will receive the exact same results since it is the same people.
It isn't D. for the exact same reason as A. but you're missing managers now.
Therefore the answer is B. Some managers and some sales executives selected at random. This way you get a sample from both categories, and within those groups, it is randomly selected.
I hope this helps!
The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12
For #30 I ended up doing a lot of adding & if I’m correct it would take about 3 to 3 & 1/2 years for Marshall & Jim to end up with the same salary. So if I’m correct the equation would be the salary + the raise. So it would be something like s + r =x. X equals the total amount of the salary + the raise put together.
For #32 I wrote it down multiple times to make sure I get it right. I ended coming up with 46<-8x8<-6x. I tried figuring out the answer to that but I didn’t understand so I went on Socratic & it said there was no solution. Yeah
Sorry I couldn’t help with the other 2. I tried my best here.
