We have given the 2 by 2 frequency table.
The probability that a randomly selected book is a nonfiction paperback =
(Number of nonfiction paperback books) / Total number of books
= 23 / 69
= 0.3333
The percentage of nonfiction paperback books is 33.33%
Answer:
x= -6, y= 10
Step-by-step explanation:
x= y + 4
2x = 3y - 2
If we replace "x" with "y+4" in the second equation we get:
2(y+4) = 3y - 2
2y + 8 = 3y - 2
2y - 3y = -2-8
-y = -10
y = 10
Now we can go back to the first equation and solve for x:
x = y + 4
x = 10 + 4 = 14
