Answer:
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:
1/6 for the old man. 1/7 for the old lady.
2/13 that they are twins.
25-4x=15-3x+10-x is all real numbers. You must simply both sides of the equation. The problem is then -4x+25= -4x+25 which is the same. If this happens the answer is always all real numbers.
