Answer:
93.25% probability that they have taken this steroid
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Positive test
Event B: Taking the steroid.
Suppose the probability of an athlete taking a certain illegal steroid is 10%.
This means that 
Given that the athlete has taken this steroid, the probability of a positive test result is 0.995.
This means that 
Positive test:
99.5% of 10%(If the athlete has taken).
100-99.2 = 0.8% of 100-10 = 90%(Athlete has not taken)
Then
Given that a positive test result has been observed for an athlete, what is the probability that they have taken this steroid
93.25% probability that they have taken this steroid
Answer: 18k + 22p - 10
The total cost would be $92.

Answer:
Step-by-step explanation:
X = Movies | Y = Video Games
Using these variables, we can set up equations.
3x + 2y = $24 eq1
8x + 4y = $57 eq2
We have here a system of equations, where we have two or more equations with two or more different variables. We use the elimination method to solve for the variables.
Multiply eq1 by 8. Multiply eq2 by 3.
24x + 16y = $192 eq1
24x + 12y = $171 eq2
Subtract eq2 from eq1 to eliminate the x terms.
4y = 21
y = $5.25
This rental cost of one video game is $5.25
Substitute the value of y into eq1 to solve for x. This will give you the rental cost of one movie.
The rental cost of one movie is $4.50
3($4.50) + 2($5.25) = $24
8($4.50) + 4($5.25) = $57
Answer:
A, B, E
Step-by-step explanation:
x(x +6)(2x -7)= 0
For the product of these 3 factors to be equal to zero, one of them (x, x+6, or 2x-7) must be a zero.
x= 0 or x +6= 0 or 2x -7= 0
x= -6 or 2x= 7
x= 3.5
Thus, options A, B and E are correct.
