Proofs do not prove that something is false, they are not always 3 parts, and they are not in any order, because they have to be in an organized sequence.
So, A is correct.
All you have to do
Is plug in 4 and 12 for X and Y
Answer: 379.94
The diameter is given as 22 inches, the radius would be 2/2 = 11 inches.
Area = 3.14 * 11^2
Area = 3.14 * 121
Area = 379.94 square inches.
Answer:
Yes, it is a function
Step-by-step explanation:
anytime you want to test to see if the graph is a function, perform a vertical line test.
Basically if you drew a vertical line and the vertical line crosses the graph at only one point that means the graph is a function.
If it crosses on more than one point the graph is not a function.
Answer: 0.0386
Step-by-step explanation:
Number of digits = 10
Number of letters in English alphabet = 26
Total number of characters = 
Now, if replication is allowed, then the total number of ways to make a ten character password will be :_
The number of ways to make a password having all letters :-
Now, the probability that the password will contain all letters will be :-
Hence, the probability that the password will contain all letters =0.0386
