Answer:
-8
Step-by-step explanation:
Since x = -18, we use the top formula
f(-18) = (x-6)/3
= (-18-6)/3
= -24/3
= -8
Answer:
The answer is 3
Step-by-step explanation:
7 - 4 = 3
So, 3+4=7
Answer:

Step-by-step explanation:
Part 1: Solve for the total amount of marbles
To solve for the probability of certain events, a population is needed to derive this information from. In order to find this population, add up the amounts of each marble.
8 + 14 + 12 = 34 marbles
Part 2: Determine the probabilities
Now, given the amounts of marbles, simply multiply the ratios of blue marbles to total marbles and the ratio of clear marbles to total marbles to get the combined probability.

The probability of these events occurring simultaneously is 15%.
Answer:
$33
Step-by-step explanation:
First we calculate the cost of the overdrafts:
3 overdrafts * $35 = $105
Then, if he maintains an average monthly balance of $600, we can calculate = $600*12 months = $7200 (average yearly balance). And the bank pays him 1% interest per annum:
$7200 * 1% = $72 (this is what the bank pays the graduate per year)
So if the bank charges him $105 and pays him $72, then the net annual cost is = $105-$72= $33
