Answer:
B. 0.4
Step-by-step explanation:
Use the definition of the probability

You have to find the probability that a randomly selected reference book is hard cover. Hence, from the table
- Number of all possible outcomes = Number of Reference books = 25
- Number of all favorable outcomes = Number of Hardcover Reference books = 10
So, the probability is

Answer:
219
Step-by-step explanation:
83 + 119 = 202
202 + 17 = 219
The table of possible values when graphing
X Y
-2 9
-1 5
0 1
1 -3
2 -7
The intercepts x (1/4,0) and y (0,1)
0.73% because you just take 100 minus 27 then add your decimal
We need to find m first.
m+n=12, n=5 (plug in n as 5)
m+5=12 (subtract both sides by 5)
m=7
m-n: we know that m is 7 and n is 5
7-5=2
The final answer is 2.
