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

Delete the ribbon is 3/4 meter Sunday needs pieces measuring 1/3 meter for in our project what is the greatest number of pieces
Bogdan [553]

Answer:the greatest number of pieces that can be cut is 2

Step-by-step explanation:

The total length of ribbon available is 3/4 meter. Sunday needs pieces measuring 1/3 meter for their project. This means that each length needed would be exactly 1/3 meter.

The number of pieces measuring 1/3 meter that can be cut from the ribbon would be

(3/4)/(1/3) = 3/4×3/1 = 9/4 = 2.25

Since the length needed is exactly 1/3 meter, the greatest number of pieces that can be cut will be 2

Prove the polynomial identity.
Kaylis [27]

Answer:

Proven

Step-by-step explanation:

We prove the polynomial with factorization. We must first simplify the expression before we can factorize:

(4\cdot{x^2}-2)\cdot{(4\cdot{x^2}-2)}-16\cdot{x^4}

16\cdot{x^4}-8\cdot{x^2}-8\cdot{x^2}+4-16\cdot{x^4}

4-16\cdot{x^2}

4 is the common number and we can take it out of the expression:

4\cdot{(1-4\cdot{x^2})}

We can factorize further with the x term being zero. For this to be true we must have -2x and 2x to cancel out and therefore the expression is proven:

4\cdot{(1-2\cdot{x})}\cdot{(1+2\cdot{x})}

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
denis23 [38]

Answer:

17 units

Step-by-step explanation:

Use the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

Plug in the points and simplify:

d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

d = \sqrt{(-8 - 7)^2 + (0-8)^2}

d = \sqrt{(-15)^2 + (-8)^2}

d = \sqrt{225 + 64

d = \sqrt{289

d = 17

So, the distance between the points is 17 units
