You want to make five-letter codes that use the letters A KE R. and Mwithout repeating any letter. What is the probability that
Crank

Answer:

0.05

Step-by-step explanation:

There are five letters to choose from. Since there is no repetition, you can choose one of 5 for the first letter, one of four for the second letter, etc. The total number of five-letter codes is

5 * 4 * 3 * 2 * 1 = 120

Now we need to find out the number of codes that start with M and end with E.

The first position is occupied by M. There is one single letter that can be placed there. The last position is occupied by E. There is a single letter that goes there. There are 3 letters left.

1 * 3 * 2 * 1 * 1 = 6

There are 6 codes that start with M and end with E

p(code that starts with M and ends with E) = 6/120 = 0.05

Which of the following is the graph of
aev [14]
The -3 at the end of the equation would be the location of the lower point on the Y axis
 and since the x-4 part is in between the vertical lines, that means the absolute value, which is always positive so the graph would make a V shape

so the correct graph would be  D
