Answer:
The mathematical expectation of a student who purchases 10 tickets is -$39.65.
Step-by-step explanation:
A student that purchases 10 tickets out of 2900 has a probability of winning the cruise that can be calculated as:
Each ticket cost $5, so he has spent $50 for the 10 tickets.
Then, the expected value of this operation is equal to the expected value of the earnings (probability of winning the prize multiplied by the value of the prize), minus the costs:
The mathematical expectation of a student who purchases 10 tickets is -$39.65.

Answer:
31.74 million people were employed.
Step-by-step explanation:
The unemployment rate is the number of unemployed people divided by the size of the labor force.
So the first step to solve this problem is finding the size of the country's labor force.
Suppose some country had an adult population of about 46 million, a labor-force participation rate of 75 percent.
So the size of the country labor force is:
0.75 * 46 million = 34.5 million people.
Unemployment rate of 8 percent. How many people were employed?
This means that 100 - 8 = 92 percent of people were employed. Remembering, this considers only the labor force, of 34.5 million people. So
0.92 * 34.5 million = 31.74 million
31.74 million people were employed.
Answer:
(-4, 0) and (5/2, 0)
Step-by-step explanation:
if you graph the equation you can see where the curve intersects the x-axis or you can factor the equation into: (2x - 5)(x + 4) = 0
set each factor equal to zero and solve:
2x - 5 = 0
2x = 5
x = 5/2
x + 4 = 0
x = -4
