Answer:
18m + 45n + 90
Step-by-step explanation:
You have to multiply whatever is inside the parentheses to the thing outside of it
like 2 x 9 is 18 so 18m
5 x 9 = 45 so 45n
9 x 10 = 90 so 90
Answer:
-45
Step-by-step explanation:
-50 + 2a represents the sum of the constant -50 and twice the value of the variable a.
If a = 2.5, then -50 + 2a has the value -50 + 2(2.5) = - 50 + 5 = -45.
The answer to the question is 3.2^6 because 6 zeros
Answer:
B. P(A|B) = P(A).
Step-by-step explanation:
Question
If a and b are independent events then it must be true that P(A|B)=P(A). TRUE OR FALSE.
Answer
The correct answer is:True.Explanation:P(A|B) is read as “the probability of A given B.” If A and B are independent, this means that B has no effect on A. This means the probability of A given B would be the same as the probability of A, since B has no effect.This means that P(A|B) = P(A).
