Answer:
C
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
Here a₁ = 4 and r = - 3, thus
= 
= 
= - (729 - 1) = - 728 → C
Can you restate it or rewrite it? It doesn't have enough for me to answer this.

Linear angles are adjacent angles whose sum is 180
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>
