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:
The point of intersection is (-1,-3)
Step-by-step explanation:
Line A has a slope of 3/2 and passes through the point (3,3)
It is equation is:
Line B has a slope of -1/3 and passes through the point (-4,-2).
It's equation is
To find their point of intersection, we solve the two equations simultaneously.
Let's equate the right hand sides:
Expand:
Put x=-1 in the first equation:
The point of intersection is (-1,-3)
