First convert 7.5 meters to 750cm, then use your formula A=1/2bh and pop it in your calculator: (1/2)(750)(6) and be sure to include cm as the unit of measurement in your final answer.
Answer:
<u>$4800</u>
Step-by-step explanation:
The expected net income is the probability when rains multiplied by net income (profit) summed with the probability of not raining with that days net income multiplied.
First, Chance of rain = 12% = 12/100 = 0.12
Profit/Loss = Income - Cost
Income is 5000
Cost = 9000
So,
Loss = 5000 - 9000 = 4000
Or, Net Income (profit) = - 4000
Now, Change of not raining = 100 - 12 = 88% = 88/100 = 0.88
Profit = Income - Cost
Income = 15,000
Cost = 9000
Net Income (profit) = 15000 - 9000 = 6000
So, we can write the expected net income as:
<u>Expected NI </u>= (0.12)(-4000) + (0.88)(6000) = <u>$4800</u>
Answer:
28/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. (6/a)x + 5 = 4
(6/a)x = -1
6x = -a
x = -a/6
2. 2ax + 7 = 13
2ax = 6
ax = 3
x = 3/a
3. -ax - 20 = -14
-ax = 6
x = -6/a
