Answer: a. 45 = k
b. d/t = 45
c. d = 45t
<u>Step-by-step explanation:</u>
The constant of proportionality (k) equals y divided by x if it is a direct variation. In the given problem, y is represented by distance (d) and x is represented by time (t).
Hi! Let me help you!
This problem is a Venn Diagram question. It is much easier to answer this question with the visual it usually comes with. However, we can employ logic to give this one a smart and logical answer.
What we have so far:
P(A) = 25. This means that the shaded area of A is equal to 25.
P(B/A) = 920. This means that area A subtracted 25 to the value of area B which resulted to 920.
P(B) = 945. How did I arrive with 945? Simple, I just added 25 to 920. Go and be a smart lad and find why I did that.
Solution:
Solving P(A∩B) is quite challenging because like I said, a visual is needed for us to give it a pefect answer. Employing logic and using what we have so far:
If P(A∩B) means A and B intersection, we can assume that it is simply as A + B.
If that is the case, then we can simply pull out our P(A) and P(B), 25 and 945 respectively and add them:
P(A) + P(B) = P(A∩B)
P(A∩B) = 25 + 945
P(A∩B) = 970 <----- What we are looking for
Therefore, P(A∩B) = 970!
