Answer:
P(B|A)=y
Step-by-step explanation:
The complete question is shown in the attachment.
If the events, A and B are independent, then
P(A and B) = P(A)×P(B)
But from the question:
P(A)=x and P(B)=y
This implies that:
P(A and B) = xy
Also, the conditional probabilities are:
P(A\B)=P(A)=x
P(B\A)=P(B)=y
Therefore the correct answer is A
Answer:
x = -1
Step-by-step explanation:
3^x = 1/3
3^x= 3^-1
x=-1
The value of each winning ticket is an arithmetic series in which T (n) = -5 + 15n or $5 (3n-1). The first winner is 5 (3x1 - 1) = $10. The second winner is 5 (3x2 - 1) = $25. The tenth ticket wins $5 (3x10 - 1) = $5 (29) = $145.
The slope of an absolute function at the point where it evaluates to zero is undefined.
Here, when x=1, so |4x-4|=|4-4|=|0|, the slope is undefined. This is where the vertex of the "V" on the graph of the absolute value function.
The answer to this question is Wyatt could walk 27 miles in 9 hours.
