im sorry i cant figure out how to remove this
Step-by-step explanation:
By addition theorem of probability,
P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8
Therefore, the probability that randomly selected person likes pizza or burger is 0.8
First, you would add 9x to both sides so that you get:
x^2 + 9x + 20 = 0.
Then, you want to factor. You want coefficients of x that add to 9 and have the constants add to 20:
(x + 5) * (x + 4) = 0
The answer is (C).
