Answer:
9.6
Step-by-step explanation:
We are rounding to the nearest tenth, so we look at the hundredth place. Since 7 is bigger than 5, we round the digit in the tenths place up. We get 9.6 as our answer.
I hope this helped and please mark me as brainliest!
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%
X>=3, basically so that sqrt(positive or zero), x-3>=0 ...
Ok, so you do regular multiplication with it, and when you have your final answer, you count the number of places behind the decimal place there are in the original numbers, and put the decimal point there. the answer is 0.049056
