<u>Answer:</u>
The expected value of construction company is $30500.
<u>Solution:</u>
Given, A construction company is planning to bid on a building contract.
The bid costs $1,500 and has an 80% chance of being accepted.
If accepted, the company will receive $40,000 dollars.
We have to find the expected value.
We know that,
Expected value = probability
amount gained by bidding – bid amount
Expected value = 80% x 40000 – 1500
Expected value = 0.8 x 40000 – 1500
Expected value = 32000 – 1500
Expected value = 30500
Hence, the expected value is $30500.

Step-by-step explanation:
Answer:
$5,909.97
Step-by-step explanation:
We will use the compound interest formula for this problem as shown below:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 3.6% into a decimal:
3.6% ->
-> 0.036
Now plug in the values:


After 2 years, the balance would be $5,909.97
Answer:
x=-3, y=5
Step-by-step explanation:
6x + 2y = -8 3x - 2y = -19
Add the two equations together to eliminate y
6x + 2y = -8
3x - 2y = -19
------------------------
9x = -27
Divide each side by 9
9x/9 = -27/9
x = -3
Now we find y
6x + 2y = -8
6(-3) +2y = -8
-18+2y = -8
Add 18 to each side
-18+18 +2y = -8+18
2y = 10
Divide by 2
2y/2 = 10/2
y =5
