For the first question the answer is
X=-9 or X=10
First you factor the left side of the question
(X+9)(X-10)=0 then u set factors equal to zero
X+9=0 or x -10=0
X=-9 or X=10
Now for question two is the second bubble of answer
Answer:
0.60
Step-by-step explanation:
Probability that the customer is not a poor risk = 1 - probability that the customer is a poor risk
Firstly, let’s calculate the probability of being a poor risk.
From the given data the number of poor risks = 14229-7362-1190 = 5677
So the probability of being a poor risk = 5677/14229 = 0.399
Thus, the probability that the customer is not a poor risk = 1-0.399 = 0.601 which to 2 decimal places = 0.60
