Following are the solution to the given points:
Step-by-step explanation:
In point a:
It's also expected that approximately
of both, the students contribute zero, approximately
to donors $10, approximately
donors $25, and then about
dollars $50 donors. Its frequencies would be similar to and not precisely, the probability. The four levels will stack up to a thousand.
In point b:
It is the population, in which the key value of x is a $0 donation ( 40 percent of students do this).
In point c:

In point d:

Answer:
a)
, b) 
Step-by-step explanation:
a) The constant of proportionality is:




b) The ordered pair is:


-5 so the answer would be -3(-5) +5 > 17
Then
15+5 > 17
Then
20 > 17
