Answer:
I only see one raffle, but the expected value of one ticket is $2. (I think)
Step-by-step explanation:
Have a nice day!
The expected value E(x) of 1 ticket is $0.40.
How to calculate the total amount?To calculate the total amount by the formula;
Amount = Ticket x Value
Raffle 1
Given;
Tickets = 800
Value = $2 per ticket
Grand ticket = $450 ...for 1
consolation =$100.. for 2
We need to find the expected value of each ticket;
First, we have to calculate the total amount of the 800 tickets
Amount = Ticket x Value
Amount = 800 x 2
Amount = 1600
Next, we have to calculate the total amount of the prizes
Amount = Ticket x Value
Amount = 450 x 200
Amount = 650
The expected value E(x) of 1 ticket is calculated:
E(x) = 650 / 1600
E(x) = $0.40
Thus, the expected value E(x) of 1 ticket is $0.40.

Find the volume and round to the nearest hundredths place when necessary.
Answer:
This is a prism since both sides are the same triangle,
Lets find the area of the triangle first then multiply it by the width which is 16.
20.5(base or height) x 13.3(height or base) = 272.65
272.65 divided by 2 ( x 1/2) = 136.325 is your area, now we multiply by the width.
136.325 x 16 = 2,181.2 mm3 is your volume.
Whenever coming across these types of volumes we must first find a shape and find its area then multiply it by the figure's height.
Formula area of a triangle:
B(base) x H(height) x 1/2(basically just dividing by 2)

Point E is located at -12 on the number line.Point F is located at point 9 on the number line. What is the distance between Point F on the number line?
Answer:
21 points
Step-by-step explanation:
Point E is located at -12 that is 12 points less than zero. And Point F is located at point 9 which means that is 9 points after zero.
So the total distance will be 12+9= 21 points between the two locations Point E and Point F.
We add the total difference from the point zero to get the total distance between the two points.

I will give the the minimum from completing the square
y = 2(x - 0.75)^2 - 6.125
as x approaches + infinity, y approaches + infinity.
as x approaches - infinity, y approaches + infinity.
It's a quadratic. The y values go to plus infinity, when x goes from - infinity to + infinity.

Complete question :
Cari owns a horse farm and a horse trailer that can transport up to 8000 pounds of livestock and take she travles with 5 horses whose combined weight is 6240
Let t represent the average weight of tack per horse, which of the following inequalities could be used to determine the weight of the tack cari can allow for each horse
Answer:
t ≤ 352
Step-by-step explanation:
Maximum allowable weight (tack and horse) = 8000 pounds
Combined weight of 5 horses = 6240
Let average weight of tack per horse = t
Average weight of tack for the 5 horses = 5t
Hence, weight of tack + weight of horse ≤ 8000
5t + 6240 ≤ 8000
5t ≤ 8000 - 6240
5t ≤ 1760
t ≤ 352

Mr. Thompson earns $ 11.52 per hour. Last week he worked 37 hours how much F.I.C.A tax did he have to pay at 7.65%?
Answer:
$32.61
Step-by-step explanation:
First, we multiply the amount he earns per hour by the amount of hours he worked. $11.52 * 37 = $426.24. Then, we figure out what 7.65% of $426.24 is, which we can do by multiplying 426.24 by 0.0765. This gives us $32.60736, but since there is no form of US money that is worth less than 1 cent, we round to the nearest cent and get $32.61.
