Answer:
9
Step-by-step explanation:
PEMDAS IS
parentheses
Exponents
Multiply and divide
Addition and subtraction
First you start with the parentheses so
1 + 2 = 3
Now you have 6/2 x 3
Multiply and divide means you either divide or multiply what ever comes first going left to right
So
6/2 = 3
3 x 3 = 9
If it was reversed we’d have
2 x 3/6 which would be
6/6 = 1
When rounding earlier, it could be screwing you out of an extra few cents that you might eventually need for tax

, then the amount of salt (y) left in the tank after (t) minutes: 
Finally:
a)
b) 
being y(t) the amount of salt (y) per unit of time (t)
Answer:
D) The original population of State A was one -fourth the times of the orignal population of State B
Step-by-step explanation:
Answer:
Step-by-step explanation:
The probability of asking for the cherries flambe and dying, P(A) = 0.5 × 0.6 = 0.3
The probability of asking for the chocolate mousse and dying, P(A) = 0.4 × 0.9 = 0.36
The probability of skipping dessert altogether = 0.1 × 0 = 0
The probability that the rich uncle dies, P(D) is
P(D) = 0.3 + 0.36 + 0 = 0.66
To determine the prime suspect, we would apply the concept of conditional probability. It is the probability of an event, A occurring given that event B has occurred. We would compare probabilities of the events A and B occurring given that event D also occurred
Therefore,
P(A|D) = 0.3/0.66 = 0.45
P(B|D) = 0.36/0.66 = 0.55
Therefore, the prime suspect is Margo because his probability is higher
