A raffle is held at MTHS ASB to draw for a $1000 plasma television. Two thousand tickets are sold at $1.00 each. Find the expected value of one ticket.

Answers

Answer 1
Answer:

Answer:

$0.5

Step-by-step explanation:

"The expected value of one ticket" is what the cost of the television covers.

If 2000 tickets are sold for $ 1 the total amount of all tickets sold is

2000.(1)= 2000

To calculate the expected value of a single ticket, we have to divide the cost of the TV by the price of all tickets sold.

(1000)/(2000)= 0.5
Answer 2
Answer: The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).

So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5

This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)

The ice skating rink charges an hourly fee for skating and $3 to rent skates for the day. Gillian rented skates and skated for 3 hours and was charged $21. Which equation represents the cost, c(x), of ice skating as a function of x, the number of hours of skating?

Answers

Answer:

The equation represents the cost, c(x), of ice skating as a function of x is c(x)=6x+3.

Step-by-step explanation:

Consider the provided information.

Let R be the per hour rate of the using the skating rink.

It is provided that $3 is the rent of skates for the day.

If Gillian rented skated and paid $21 after 3 hours of skating, this can be represented as:

21=3R+3

3R=18

R=(18)/(3)=6

Therefore, the hourly fee for skating is $6.

Now, write the equation represents the cost c(x) of the ice skating as a function of x.

Total cost = Number of hours × Hourly fee + Rent skates for the day.

Replace total cost with c(x), Number of hours with x, Hourly fee with 6 and rent skates of the day with 3.

Thus the required equation is:

c(x)=6x+3

Thus, the equation represents the cost, c(x), of ice skating as a function of x is c(x)=6x+3.
c(x) = 6x + 3

$6 per hr..and $3 for the skates

check..
c(x) = 6x + 3
he skated for 3 hrs and was charged $21
c(3) = 6(3) + 3
c(3) = 18 + 3
c(3) = 21
.so it is c(x) = 6x + 3

A farmer builds a rectangular pen with a perimeter of 116 feet. If the length is 5 feet more than the width, what is the width?

Answers

The formula for the perimeter of a rectangle is:
A=2l+2w.
We know the area is 116, so we can plug that in for A. Now, we cant solve the equation yet because it still has two variables. Since we know the length is 5 feet greater than the width, we can rewrite l in terms of w. So here is what our new equation will look like:
116=2(w+5)+2w
Now lets solve:
116=2w+10+2w
106=4w
w=26.5 ft.
The width is 26.5 ft.

When a point lies on the x-axis, what do you know about its y-coordinate? When a point lies on the y-axis, what do you know about its x-coordinate?

Answers

When the point lies on the x-axis, its corresponding y-coordinate is zero. Similarly, when the point lies on the y-axis, the corresponding x-coordinate is also zero. To see this for yourself, you can draw on a piece of paper a coordinate plane with the two axes, x-axis and y-axis. Try drawing a point on the x-axis and see that its y-coordinate is really zero. You can do this for the point on the y-axis as well.

What are the values of x in the equasion x(x-6)=4(x+6)

Answers

x(x - 6) = 4(x + 6)
x^2 - 6x = 4x + 24
x^2 - 6x - 4x - 24 = 0
x^2 - 10x - 24 = 0
(x - 12)(x + 2) = 0
x = -2, 12

The answer is: x = -2 and x = 12.
The answer is 2(8-6)=4(-4+6)

Joel earns $1,500 per month. If he spends $375 on rent each month, what percent of his income does he spent on rent?

Answers

So taking part over the whole month you will get % spent.

375/1500 = .25
Convert to percent by multiplying by 100.

.25 x 100 = 25%

He spends 25% of his income on rent each month.
