What is a probability tree diagram?Without utilizing sophisticated calculations, a probability tree diagram is used to show the probability that an event will occur. It shows each potential result of an action. A probability tree serves as a visual representation of all the outcomes of an event while also calculating the probability of each occurrence.Given is a probability tree diagram with the respective probabilities of winning and losing a game by the teams.
To find the probability of the team winning exactly one of their two games multiply their probabilities of winning in the first game and losing in the second game and vice versa and find the sum of the two cases.
From the probability tree diagram,
P = (0.83 × 0.06) + (0.17 × 0.52)
P = 0.0498 + 0.0884
P = 0.1382

A cylinder tank has a radius of 7.5 feet and an altitude of 14 feet. If a gallon of paint will cover 130 ft.² of surface how much paint is needed to put two coats of paint on the entire surface of the tank?
Remember that
The surface area of a cylinder is equal to

Answers
After solving basic arithmetic, we have come find that it will take 40 mins for Ben to fill 48 envelopes.
What is arithmetic?The word "arithmetic," which comes from the Greek word "arithmos," which means "number," is one of the oldest and most basic branches of mathematics. The study of numbers, particularly the characteristics of conventional operations, including:
Addition
Subtraction
Multiplication
Division
These operations are the basis for the arithmetic operators ‘+’, ‘-’, ‘×’ and ‘÷’.
The foundational subject in mathematics, arithmetic covers operations with numbers. These include addition, subtraction, multiplication, and division. One of the vital branches of mathematics, arithmetic serves as the cornerstone for students studying the subject of mathematics.
Given that he can fill 36 envelopes in 30 minutes
So time he would take to fill 1 envelope = 30/36
Therefore, time he would take to fill 48 envelopes = (30/36) × 48
= 40 mins.
Thus, It will take 40 mins for Ben to fill 48 envelopes.

Stefan sells jin a bicycle for $113 and a helmet for $19. The total cost for jin is 110% of what stefan spent originally to buy the bike and helmet. How much did stefan spend originally? How much money did he make by selling the bicycle and helmet to jin?
Answers
Stefan spent originally to buy a bike $95 and $15 to buy a helmet and he made $17.27 by selling the bicycle and $1.73 by selling the helmet to Jin.
The selling cost for Stefan bicycle = $113 and
the selling cost of a helmet = $19.
The total cost for Jin is 110% of the money spent by Stefan
Let us assume purchasing cost of a bicycle = $x.
Purchasing cost of a helmet = $y.
For bicycle
110% of x is $113
=> 1.10 × x = 113
Dividing both sides by 1.10, we get
x=$102.72.
Stefan spent for his bicycle = 102.72
For helmet.
110% of y is $19.
=> 1.10 × y = 19.
Dividing both sides by 1.10, we get
y = $17.27
Stefan spent for his helmet = 17.27
money made by selling the bicycle is $113 - 102.72 = $10.72
money made by selling the helmet is $19 - 17.27 = $1.73.
Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet and he made $17.27 by selling the bicycle and $1.73 by selling the helmet to Jin.

a polygon is a 2d shape with all straight edges. show via induction that the sum of the interior angles of a polygon with n sides is (n −2) ×180◦. don’t include unneeded base cases. hint 1: it is helpful to know that a triangle’s interior angles always sum to 180◦. you may assume this is true for the problem. hint 2: in order to apply your inductive hypothesis to a polygon, you’ll need to think of it in terms of a smaller polygon. how can you make a smaller polygon out of a big one?
Answers
Using the process of induction we can prove that the sum of all angles of a polygon is (n −2) ×180°
In geometry, a polygon is a planar shape characterized by a finite number of segmented straight lines linked to form a network of closed polygons (or polygonal circuit). A polygon is defined as either a bounded plane region or a bounding circuit.
Sum of all angles of a triangle is 180°
Sum of all angles of a quadrilateral is 360°
We know that a triangle has 3 sides.
Hence (n −2) ×180 for n=3 given 180
and (n −2) ×180 for n=4 gives 360.
So we can say that the formula holds by the properties of induction.
The portions of a polygonal circuit are known as its margins or sides. A polygon's vertices or corners are the points where two edges meet. The inside of a solid polygon is sometimes referred to as its body. An n-gon appears to be a polygon with n sides, similar to a triangle, which is a 3-gon.
Hence the formula (n −2) ×180◦ holds for induction.

Two years ago, a car was valued at $24,000. This year, the value of the car is $23,160. What was the percent decrease in the value of the car?
Answers
The value of the car is decreased by 3.5%.
A figure or ratio stated as a fraction of 100 is called a percentage. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
The value of the car two years ago was $24,000.
The value of the car this year is $23,160.
The decreased value of the car after two years will be:
= $24,000 - $23,160
= $840
Let y be the percentage by which the value of the car decreased,
y = 840/24000
y = 0.035
y = 3.5/100
y = 3.5%
The value of the car decreased by 3.5 percent in two years.

Answer:
The second option: f(x) = -(200/x)
Step-by-step explanation:
We can see that the input of the function is 20 and the output is -10. For the inverse, these values will swap: -10 will be the input and 20 will be the output.
Given that, we can substitute -10 into each equation and use trial and error to find out which one gives 20 as the output.
The first one, f(x) = -(0.5/x) will give an output of -(0.5/-10) = 1/20, which is incorrect.
The second one, f(x) = -(200/x) will give an output of -(200/-10) = 20, which is correct. Therefore, this must be the inverse. There will only be one inverse, so we don't need to try the rest.

Answers
The equation can be modelled by 23 = 12 + x
How to determine the addition equation?The given parameters are
Cost of book = $12
Total purchase = $23
The total purchase can be calculated by adding the cost of the book and the cost of the T-shirt
This is represented as
Total purchase = Cost of book + Cost of T-Shirt
So, we have
23 = 12 + x
Where x represent the unknown information.

Step-by-step explanation:
Volume of the cylinder = π (3)^2 7

Volume of the cone = 1/3 π r^2 7 where r is the new radius of the cone

spend $13.75 on 2 hotdogs, 1 drink, and 3 pretzels. Write a system of equations and solve for the price of each item
Answers
Answer:
x = $3.5
y = $2.25
z = $1.5
Step-by-step explanation:
let x = price of a hotdog
y = price of a drink
z = price of a pretzel
according to the question:
Davis family spends: 3x+2y+z = $16.50 (equation 1)
Ruiz family spends: 4x+4y+2z = $26 (equation 2)
Cho family spends: 2x+y+3z = $13.75 (equation 3)
from eq. 1
z = 16.50-3x-2y
substituting in eq.2
4x+4y+2(16.50-3x-2y) = 26
4x+4y+33-6x-4y=26
-2x=26-33
thus x = $3.5
from eq. 3
y = 13.75-2x-3z
y = 13.75-2(3.5)-3z
y = 13.75-7-3z
y=6.75-3z
thus,
z = 16.50-3(3.5)-2(6.75-3z)
z = 16.50-10.5-13.5+6z
z-6z = -7.5
-5z = -7.5
thus z = $1.5
thus
y = 6.75-3(1.5)
y = $2.25
