Answer:
Your expected gain is of $10.7.
Step-by-step explanation:
Expected earnings:
The expected earnings is each prize multiplied by it's probability of being earned.
So
5% probability of earning $25.
5*15% = 75% probability of earning $15.
20% probability of earning $1. So
0.05*25 + 0.75*15 + 0.2*1 = 12.7
Cost of token:
The token costs $2, which means that we subtract $2 from the expected earnings.
12.7 - 2 = 10.7
Your expected gain is of $10.7.
The lateral areas of two similar cylinders are 196π in^2 and 324π in^2. The volume of smaller cylinder is 1715π in^3. Find the volume of the larger cylinder.
Answer:
3,645 π in³
Step-by-step explanation:
the ratio of the radius :
r1 : r2 = √196 : √324
= 14 : 18
= 7 : 9
the ratio of the volume:
v1 : v2 = 7³ : 9³
= 343 : 729
so, the volume of the larger cylinder =
729/343 x 1715π = 3,645 π in³
Answer:
since the cylinders are similar their area and volume will be proportional
[tex]\frac{lateral\:area \:of \:smaller \:cylinder}{laternal\: area \:of \:larger\: cylinder}=\frac{volume \:of\: larger\: cylinder}{volume \:of \:larger \:cylinder}[/tex]
[tex] \frac{196π}{324π}=\frac{1715π}{V}[/tex]
V=1715π*324π/126π
V=4410πin³
the volume of the larger cylinder is 4410πin³.

2. The cost of a bicycle is * 2895. Find the cost of 1486 bicycles,
. A truck can carry 6785 kg of goods. How much can 759 trucks carry?
Answer:
4,301,970
5,149,815
Step-by-step explanation:
The cost of a bicycle is 2895
Therefore the cost of 1486 bicycles is
= 2895×1486
= 4,301,970
A truck can carry 6785 kg of food
Therefore the amount in which 759 truckj can carry can be calculated as follows
= 6785×759
= 5,149,815

What is the measure of ∠E?
Answer:
80 degrees
Step-by-step explanation:
first we need to find the measure of F, we know a straight line equals 180 so we subtract 120 from 180
180-120=60
then add that to angle D
60+40=100
and all triangle angles add up to 180 so subtract 100 from 180
180-100=80
80 is your answer

VolumeSurface area==========================================
Explanation:
The volume is the amount of stuff that a container can hold on the inside, while the surface area is the amount of stuff that goes on the outside of the container (eg: the amount of paint or wallpaper). In the case of wallpapering a room, we're actually doing the inner walls rather than the outside walls; however, it's the same concept. The surface area only deals with the surface and we want to find out how much area we have to cover. That way we can know how much wallpaper to buy. For problem 1, he needs to know the volume so he can find out how much trash each can would be able to hold. The greater the volume, the larger the bin. For instance a small wastebasket would have a small volume compared to a large waist high heavy duty trash container.

Explain the meaning of probability. What does it mean if an event has a probability of 0? Give an example. What does it mean if an event has a probability of 1? Give an example. What does it mean if an event has a probability of 1/2? Give an example. (LONG ANSWERS ONLY)
Answer:
If an event has a probability of 0 it means that it is impossible. For example when they say there is 0% of rain. It is very unlikely it is going to rain. If an event has a probability of 1 it means that it is certain. For example, if they say there is a 100% chance it is going to rain. It is very certain that it's going to rain. If an event is 1/2 then it means there it is likely as it is unlikely. For example, if they say there is a 50% chance of rain. Then it might not rain, but there is a chance that it might rain as well.
Step-by-step explanation:
Hope this helps!
Probability can simply be defined as the chances of an event a, occuring with respect to event b, with respect to event n, given an nth number of possible outcomes.
Probability can be calculated using the following expression:
[tex] \frac{freq \: of \: event \: n}{freq \: of \: total \: number \: of \: events} [/tex]
When an event has a probability of 0, it means that by no chance or condition will the event be true. For example, the probability of a person who is a boy has 0 probability that he is a girl.
When an event has a probability of 1, it means that with every chance or condition, the event will be true. For example, the probability that a person who is a boy has a probability of 1 that he is a boy.
An event that has a probability of 1/2 means that the event could either return a probability of 0 or 1 on different chances or conditions. For example, the probability of a fuetus whose gender is not known has a probability of 1/2 for being a boy and 1/2 for being a girl.

The common difference is: -0.75
Step-by-step explanation:
Given

Required
The common difference
From the graph, we have:
[tex]T_n: -3.75, -4.5, -5.25, -6, -6.75, -7.5, -8.25, -9.[/tex]
The x coordinates represent the position of each term
The common difference (d) is:
[tex]d = T_n - T_{n-1}[/tex]
Let [tex]n = 2[/tex]
[tex]d = T_2 - T_{2-1}[/tex]
[tex]d = T_2 - T_1[/tex]
So, we have:
[tex]d = -4.5 - (-3.75)[/tex]
[tex]d = -4.5 +3.75[/tex]
[tex]d = -0.75[/tex]
8. At a wholesale food distribution center, the price of sugar has increased 6.3% annually since 1980.
Suppose sugar cost $0.43 per pound in 1980 and this growth continues. What will a pound of sugar
cost in 2017? Use y = a(1 + r) and round to the nearest cent.
a. $4.12 b. $1.21
c. $0.42 d. $3.30
Answer: A. $4.12
Step-by-step explanation:
Y=a(1+r/n)^nt is the equation we use to solve this.
a= $0.43
t=37 - take 1980 and subtract it from 2017
r= .063 - the 6.3% goes into a decimal
n = 1
Y= ?
Y= 0.43( 1+ .063/1) ^1*37
Y= 0.43 (1.063) ^37
Y= 4.12

The lateral area of a cube is 36 square inches. How long is each edge?
Answer:
8
3
Step-by-step explanation:
Volume of a cylinder = πr²h
Volume = 3207
Radius, r
Height, = 5
320π = π * 5 * r²
320 = * 5 * r²
320 = 5 * r²
r² = 320/ 5
r² = 64
r = 8 m
The lateral surface area of a cube is
LSA = 4s²
Where s = edge length
36 = 4s²
s² = 36/4
s² = 9
s =. sqrt(9)
s = 3
