In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Aaron sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
41 visitors purchased no costume.
78 visitors purchased exactly one costume.
10 visitors purchased more than one costume.
If next week, he is expecting 2000 visitors, about how many would you expect to buy more than one costume? Round your answer to the nearest whole number.

Answers

Answer 1

Answer:

115

Step-by-step explanation:

41 no costume, 78 exactly one costume, 10 more than one costume.

41+78+\color{steelblue}{10}=

41+78+10=

\,\,\color{indianred}{129}

129

There were a toal of 129 visitors. 10 purchased more than one costume.

Probability the next customer will purchase more than one costume:

\frac{\color{steelblue}{10}}{\color{indianred}{129}}\phantom{=}

129

10

​  

=

\,\,

Out of 2000 new trials, we would expect more than one costume to be selected:

\color{purple}{2000}\times\frac{\color{steelblue}{\color{steelblue}{10}}}{\color{indianred}{\color{indianred}{129}}}=

2000×  

129

10

​  

=

\,\,155.038759...

155.038759...

\approx

\,\,155

155

Answer 2

The number of visitors that expect to buy more than one costume will be 155.

What is the expected value?

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

Aaron creates a website where players may trade and purchase these costumes. The numbers below show how many people visited the website and how many costumes were bought in a single day.

The probability of visitors purchasing more than one costume is calculated as,

p = 10 / (41 + 78 + 10)

p = 10 / 129

If next week, he is expecting 2000 visitors. Then the expected value is given as,

E = 2000 x (10 / 129)

E = 155.038

E ≈ 155

The number of visitors that expect to buy more than one costume will be 155.

More about the expected value link is given below.

What is the volume of a cylinder with a
height of 18.5 m and a base with a
diameter of 5.2 m, to the nearest tenth of a
cubic meter?

392.9 m^3 is the real answer

Answers

Answer:

Yes it is is 392.9 m^3

Step-by-step explanation:

Volume of cylinder is π*r^2*h, π times radius squared times height.

Since the diameter is 5.2, the radius is 2.6 (half of it). 2.6^2 = 6.76, and the height is 18.5, 6.76*18.5 = 125.06. Multiply it by pi to get 392.887577258, round it to 392.9, The volume is 392.9 cubic meters.

Kevin and Doreen each made a fruit salad. The amounts of ingredients they have are shown. Kevin used all of the​ strawberries, blueberries, and melon to make his fruit salad. Doreen made 2 cups of fruit salad containing all of the​ bananas, peaches and apples. How much fruit salad did Kevin​ make? How much more fruit salad did Doreen make than​ Kevin?

Answers

Answer:

The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.

The function represented by the table is

y = 0.25x

Then, as Mandie is making 15 glasses of fruit salad, we have:

y + x = 15

We have two equations and two unknowns that we must solve.

y = 0.25x

y + x = 15

Resolving

For x:

0.25x + x = 15

1.25x = 15

x = 15 / 1.25 = 12

For y:

y = 0.25x = 0.25 (12) = 3

Martha's mother has marked the cake into 10 equal pieces starting from 0 t0 9

Now, she divided the cake in a manner that sum of digits on each of the three pieces is equal

0,1,2,3,4,5,6,7,8,9

(9,6,0)  (8, 4,3), (7,5, 1,2)

4. Paolo is filling a cylindrical water bottle. Unfortunately it is too big to fit in the sink he is filling up at so he has to use cone cups to fill up the bigger water bottle. The cone cups have a radius of 1 in, and a height of 3 in. how many cone cups would it take to fill the cylindrical water bottle?​

Answers

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, we need to be given the dimensions of the big cylindrical water bottle. Let us assume, that the big bottles has a dimension of radius 3 in and height 5 in.

Solution:

Firstly, we need to find the volume of the big cylindrical bottle, then we find the volume of the small cone.

Volume of the cylindrical bottle = πr²h = π(3²)5 = 45π in³

Volume of the small cone = πr²h/3 = π(1²)(3/3) = π in³

Therefore the number if cups required to fill the water bottle is the ratio of the volume of the cylinder to the volume of the small cone. Hence:

number of cone cups = 45π in³ / π in³ = 45 cups

Hence 45 cups of the cone would be needed to fill the cylindrical bottle

Suppose a call center receives 4000 calls on average during their Friday evening shift. Next Friday several people have put in for time off, so the center will be staffed by 178 call center employees. When working continuously, the average call center employee can handle 22 calls per evening shift (with a standard deviation of 5 calls). Assuming the center receives its expected 4000 calls next Friday, what is the probability that the center will have enough employees to handle this call volume

Answers

Answer:

The probability that the center will have enough employees to handle this call volume is 0.2764

Step-by-step explanation:

Probability is defined as the ratio of favorable outcomes to the total number of outcomes.

Here the total mean expected number of outcomes=u = 4000

The favorable  expected outcomes are = x= 22* 178= 3916

The  standard deviation= σ= 5

The random variable X =178 has normal distribution with mean 4000/22 and standard deviation 5

So z= x-u/σ

Z= (3916-4000)/22/5

z= -0.764

From the table of areas under normal curve

P (  x= 3916)=  P( -0.764 ≤ Z≤ 0)

P (  x= 3916)=  0.2764

The probability that the center will have enough employees to handle this call volume is 0.2764

B. $28,550
C. $29.500
D. $30,570​

Answers

Answer: $29500

Step-by-step explanation:

Given the information from the question, the net income will be calculated as:

Net sales = Gross profit - sales returns and allowances

= $50000 - $6,000

= $44000

Gross profit = Net sales - Cost of goods sold

= $44000 - $10000

= $34000

Net income = Gross profit - Operating expense

= $34000 - $4500

= $29500

Answer:

Interest earned = $32.835

Step-by-step explanation:

Given the following data;

Principal = $275

Number of times = 0.5

Interest rate = 2.9% = 0.029

Time = 4 years

To find the interest earned, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 275(1 + \frac{0.029}{0.5})^{0.5*4}[/tex]

[tex] A = 275(1 + 0.058)^{2}[/tex]

[tex] A = 275(1.058)^{2}[/tex]

[tex] A = 275(1.1194)[/tex]

A = $307.835

Interest earned = 307.835 - 275

Interest earned = $32.835
