Answer:
x = (-5 ± 2√10) / 3
Step-by-step explanation:
5 − 10x − 3x² = 0
Write in standard form:
-3x² − 10x + 5 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)
x = [ 10 ± √(100 + 60) ] / -6
x = (10 ± 4√10) / -6
x = (-5 ± 2√10) / 3
Based on the cost of the contract and the probability to win it, the total expected value of the contract proposal is -$2500.
<h3>How to calculate the expected value of a contract proposal?</h3>
The general formula to calculate the expected value is:
- Expected value: possibility of winnind the contract x the amount when winning - possibility of loing the contract x possible loss
- Possibility of winning the contract= 0.10
- Possibility of losing the contract = 0.90
- Gain: $65000
- Loss: $10000
<h3>What is the expected value of the contract?</h3>
- Expected value: 0.10 x 65000 - 0.90 x 10000
- Expected value: 6500 - 9000
- Expected value: -$2500
