Answer:

The expected value of the lottery is $80

Step-by-step explanation:

To get the expected value, we have to multiply each outcome by its probability

Then we proceed to add up all of these to get the expected value of the lottery

we have this as ;;

125(0.2) + 100(0.3) + 50(0.5)

= 25 + 30 + 25 = $80

KatRina [158]

Answer:

the building would be 280 feet (judging on how this is worded.)

Step-by-step explanation:

you are already 100 meters from the base ( bottom) of the building so you add 180 as you are 180 ft from the top of the building. 100 + 180 is equal to 280.

The Scooter Company manufactures and sells electric scooters. Each scooter cost $150 to produce, and the company has a fixed cos
jeka94

The function that represents the Scooter Company's total profit is given by:

P(x) = -2x² + 250x - 2,000.

<h3>How to calculate the profit function?</h3>

The profit function is calculated by the <u>revenue function subtracted by the cost function</u>, hence:

P(x) = R(x) - C(x).

In this problem, we have that:

  • The revenue function is: R(x) = 400x - 2x².
  • The cost function is: X(x) = 150x + 2000.

Hence the profit function is:

P(x) = R(x) - C(x).

P(x) = 400x - 2x² - (150x + 2000).

P(x) = -2x² + 250x - 2,000.
