In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Fatoumata 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.
7 visitors purchased no costume.
143 visitors purchased exactly one costume.
16 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a fraction in simplest form.
Answers
The probability that the next person will purchase no costume is 7/166 if the 7 visitors purchased no costume.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Total number of visitors = 7+143+16 = 166
Number of visitors purchased no costume = 7
The probability that the next person will purchase no costume:
= 7/166
Thus, the probability that the next person will purchase no costume is 7/166 if the 7 visitors purchased no costume.

Answers
Answer:
29.4°
Step-by-step explanation:
The equation can be rearranged to give C directly.
C = arccos((a^2 +b^2 -c^2)/(2ab))
C = arccos((90^2 +55^2 -50^2)/(2·90·55))
C = arccos(8625/9900) ≈ 29.4002°
C ≈ 29.4°
The measure of angle C is approximately 29.46 degrees.
How to determine angle CTo find the measure of angle C (cos(C)) using the given values a = 55, b = 90, and c = 50, we can use the Cosine Rule formula:
cos(C) = (a² + b² - c²) / (2 * a * b)
Substitute the given values:
cos(C) = (55² + 90² - 50²) / (2 * 55 * 90)
Now, calculate the numerator:
cos(C) = (3025 + 8100 - 2500) / (2 * 55 * 90)
cos(C) = 8625 / 9900
Now, divide to get the final value of cos(C):
cos(C) ≈ 0.8707
To find the measure of angle C itself, we can take the inverse cosine (arccos) of this value:
C ≈ arccos(0.8707)
Using a calculator, you'll find:
C ≈ 29.46 degrees (rounded to two decimal places)
So, the measure of angle C is approximately 29.46 degrees.

How much do you need to save per month to fund the emergency fund, and how much discretionary money remains per month?
Answers
The amount that you need to save per month to fund the emergency fund would be $ 861. 58.
The discretionary money left per month would be $ 585. 88.
How to find the amount to save ?The gross income for the month :
= 17. 50 x 40 per week x 4 weeks a month

Jamie went out to her grandfather's farm.
Her grandfather has pigs and chickens on his farm.
She noticed that there were a total of 26 heads and
68 feet among them. How many chickens and how
many pigs did her grandfather have?
Answers
Answer:
8 pigs
Step-by-step explanation:
Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.
Suppose all animals are chickens.
Total no. of feet = 26 chickens × 2 feet
= 52 feet
Difference in total no. of feet = 68 feet - 52 feet
= 16 feet
Difference in no. of feet each animal has
= 4 feet (a pig) - 2 feet (a chicken)
= 2 feet
∴ No. of pigs = 16 feet ÷ 2 feet
= 8 pigs

Interval notation is a way of writing the subsets of the real number line.
There are 2 types of brackets used to represent two types of intervals on the number line.
A closed interval is one that includes its endpoints. Closed brackets, [ ], are used to write out the intervals. For example, the interval 0 ≤ x ≤ 3 is represented as:
\(\lbrack0,3\rbrack\)An open interval is one that does not include its endpoints. Open brackets, ( ), are used in this case. For example, the interval 0 < x < 3 is represented as:

Axis of symmetry: x = 5
Vertex form: y = -4(x - 5)² + 3
Step-by-step explanation:
Given ordered pairs: (2, -33) (3, -13) (4, -1) (5, 3) (6, -1)
Axis of Symmetry
As this is a parabola, it will be symmetrical.
To determine the axis of symmetry, identify two ordered pairs that have the same y-values and find their midpoint.
Two ordered pairs with the same y-value: (-4, 1) and (6, -1)
Midpoint of x = 4 and x = 6 is: x = 5
Therefore, the axis of symmetry is x = 5
Vertex form
Vertex form of a quadratic equation: y = a(x - h)² + k
(where (h, k) is the vertex)
The axis of symmetry is the x-value of the vertex of the parabola.
As we have been given the point when x = 5, the vertex is: (5, 3)
Substituting this into the formula:
⇒ y = a(x - 5)² + 3
To find the value of a, substitute any of the other points into the formula and solve for a.
Using (4, -1)
⇒ a(4 - 5)² + 3 = -1
⇒ a(-1)² = -4
⇒ a = -4
Therefore, the vertex form of the parabola is:
y = -4(x - 5)² + 3

How to solve if the statement is trueIn the first month, the price of the avocado is said to have been raised by 30 percent.
While already raised by 30 percent, another 30 percent raise would make the increase to be 60 percent.
While is at 60 percent, the third month the raise would be = 90 percent because 30 * 3 = 90

The mean height of three boys is 150 centimeters. The mean height of two girls is 145.Find the mean height of five students
Answers
A mean is an arithmetic average of a set of observations. The mean height of the five students is 148.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
Given that the mean height of three boys is 150 centimeters. Therefore, the sum of height of the three boys is,
Mean Height of boys = Sum of height of boys / Number of boys
150 = Sum of height of boys/ 3
Sum of height of boys = 150 x 3 = 450
Also, given that the mean height of two girls is 145 centimeters. Therefore, the sum of height of the two girls is,
Mean Height of girl = Sum of height of girls/ Number of girls
145 = Sum of height of girls/ 2
Sum of height of girls = 145 x 2 = 290
Further, the mean height of five students is,
Mean height of five students = Sum of height of students / Number of students
Mean height of five students = (450 + 290)/ 5
Mean height of five students = 740 / 5
= 148
Hence, the mean height of the five students is 148.

Step-by-step explanation:
Glass 1 is a right circular cylinder and Glass 2 is a cone. The total volume of water in both the glasses is 100 centimeters cubed. Some given dimensions are:
Right Circular Cylinder:
diameter = 5, thus radius is half of that, radius = cm
height = we need to find
(Note: Formula for volume, V, is )
Cone:
diameter = 6, thus radius is half of that, radius = cm
height = 5.2 cm
(Note: Formula for volume, V, is )
Now adding the 2 volumes and equating to 100, and then solving for h will give us our answer (we will use π as 3.14). Let's do this.

Elroy bought a $4210 custom video gam e/ virtual sound system on a special no-interest plan. He made
Answers
The amount of the last payment that Elroy will make is $710, which includes the $200 monthly payment and a balance of $510.
How is the last payment determined?The last payment amount is the result of the mathematical operations of subtraction and multiplication.
The first mathematical operation was the subtraction of the down payment from the total cost of the video game system.
Using multiplication, the monthly payments are determined to be $3,400 for 17 months. This is subtracted from the remaining balance to obtain the last payment amount.
The cost of a custom video game/virtual sound system = $4,210
Down payment = $100
The remaining balance for monthly payment = $4,110 ($4,210 - $100)
Payment period = 18 months (1¹/₂ years)
Monthly payments = $200
Payment for the first 17 months = $3,400 (17 x 200)
Last payment = $710 ($4,110 - $3,400)
Thus, if Elroy makes the minimum monthly payment of $200 till the last payment, then he will pay $710 to settle the account.

Buenos días! Me gustaría que me ayudarán con la respuesta de una pregunto matemática por favor. Es a pasar a F(x) -1
Answers
Buenos días! ¡Claro que sí! Para pasar una función f(x) a F(x) - 1, simplemente debemos restar 1 a la función original.
Si f(x) = 3x^2 - 4x + 1, entonces:
F(x) = f(x) - 1
F(x) = (3x^2 - 4x + 1) - 1
F(x) = 3x^2 - 4x
Por lo tanto, la función F(x) obtenida al restar 1 a la función f(x) = 3x^2 - 4x + 1 es F(x) = 3x^2 - 4x.
