The answer is <span>a. T(n+1)=1/2n^2+3/2n+1
</span>
T(n) = 1/2n² + 1/2n = 1/2(n² + n)
T(n + 1) = 1/2((n+1)² + (n+1))
(a + b)² = a² + 2ab + b²
(n + 1)² = n² + 2n + 1
T(n + 1) = 1/2(n² + 2n + 1 + n + 1) =
= 1/2(n² + 3n + 2) =
= 1/2n² + 3/2n + 1
X=17 is the awnser for this
The Answer to this problem is (the line y=x). I'm positive that this is the right answer!!!
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
