Is 1/4(8y-12) equivalent to 2y-12 explain why or why not

Mathematics
1 answer:
Vanyuwa [196]3 years ago
8 0

Answer:

No

Step-by-step explanation:

First simplify the first expression.

Distribute.

1/4(8y-12) = 1/4 * 8y + 1/4 * -12

8y * 1/4 = 8y / 4 = 2y

-12 * 1/4 = -12 / 4 = -3

1/4(8y-12) = 2y - 3

2y - 12 != 2y - 3

So it is not equivalent.

g Which of the following is equivalent to P( A|B)? a. P(A and B) b. P(B|A) c. P(A)/P(B) d. None of these choices.
Scilla [17]

Answer:

The correct option is D.

But option B is correct if P(A) = P(B).

Step-by-step explanation:

P(A|B) is read as "The probability of A given B".

It is different from the options A, B, and C.

It is equal to option B only if the probability of A is equal to the probability of B. That is P(A|B) = P(B|A) if P(A) = P(B).
