Alrighty
mindy+troy=9
mindy=3
3+troy=9
minus 3 both sides
troy=6
troy had 1/4 of tottal
6=1/4 of total
times 4 both sides
24=total
the cake had 24 pieces in total
Answer:
Correct option is c.
Step-by-step explanation:
The information provided is:
- It costs $83 a day to rent a car plus a required fee for insurance.
- The total cost for renting the car for 7 days is $621.
Then the cost of renting the car for 7 days will be, (83 × 7).
Let <em>b</em> denote the required fee for insurance.
Then the equation representing the total cost of renting is:
621 = 83(7) + b
Compute the value of <em>b</em> as follows:
621 = 83(7) + b
621 = 581 + b
b = 40
So, the correct option is c.
<u>Answer:</u>
P (S∩LC) = 0.03
<u>Step-by-step explanation:</u>
We are given that the probability that someone is a smoker is P(S)=0.19 and the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158.
Given the above information, we are to find the probability hat a random person is a smoker and has lung cancer P(S∩LC).
P (LC|S) = P (S∩LC) / P (S)
Substituting the given values to get:
0.158 = P(S∩LC) / 0.19
P (S∩LC) = 0.158 × 0.19 = 0.03
