Answer:
the answer is x=2 and y=3
Step-by-step explanation:
y=3 for x=2
y=3;x=2
x=2 and y=3
$6x$5=$30
$50-$30=$20
So 5 books?
Or
50=6x5+x
x=20
<u>Answer:</u>
P(A') = 0.75
<u>Step-by-step explanation:</u>
We are given that the probability P(A) = 0.25 and we are to determine the probability of the complement of A.
According to the Complement Rule of any probability, the sum of the probabilities of an event and its complement must be equal to 1.
So for for the event A,
P(A) + P(A') = 1
0.25 + P(A') = 1
P(A') = 1 - 0.25
P(A') = 0.75
