COMPLETING THE SQUARE (PROCESS):
Do a reverse factoring procedure to develop the following form of equation:
(t + a)^2 = b
where:
t = unknown variable
a = coefficient
b = coefficient
Then take square root of both sides to find value of unknown variable as follows:
t^2 + 10t = 75
(t^2 + 10t + 25) = 75 + 25
(t^2 + 5t + 5t + 25) = 100
(t + 5)(t + 5) = 100
(t + 5)^2 = 100
√(t + 5)^2 = √100
Two solutions exist:
+(t + 5) = 10
AND
-(t + 5) = 10
Thus:
t = 10 - 5 = 5
AND
t = -5 - 10 = -15
Answer:
t = 5
AND
t = -15
Answer:
A. 7%
Step-by-step explanation:
We build the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a resident owns a car.
B is the probability that a resident owns a truck.
We have that:
In which a is the probability that a resident has a car but not a truck and is the probability that a resident has both a car and a truck.
By the same logic, we have that:
4% of residents own both a car and a truck.
This means that
56% of residents own a car
This means that . So
What is the conditional probability that a person who owns a car also owns a truck?
So the correct answer is:
A. 7%

B
