Answer:
1. Not possible
2. Possible
3. 24
4. C
5. D
Step-by-step explanation:
Some key concepts to remember:
- One -to -one means each element has an element only it matches to. This is only possible when sets have the same number of elements. #1 doesn't but #2 does.
- To determine the number of one-to-one correspondence, use a factorial with the number of elements. 4 is the number and the factorial is 4! = 4*3*2*1 = 24.
- n(A) means the cardinal number of the set or the number of unique elements. Elements count only once even if they repeat. There are 5 in #4 and 12 in #5.
Rate of change is slope aka y=mx+b the mx is the slope. For this equation the rate of change is 7

Hi there.
100 mph; how long would it take to drive 211 miles?
The answer here is rather simple. Divide 211 by 100 to determine how many hours it will take.
211 / 100 = 2.11
This means it will take 2 11/100 (or 2.11) hours to drive 211 miles.
I hope this helps!
