A spinner is spun `40` times for a game.
This graph shows the fraction of games that are wins.
Based on the graph, what is the probability of a spin winning this game?
(i) In decimals: 0.65
(ii) In percentage: 65%
The graph shows that after the spinner is spun after 40 times. The Fraction of wins is 0.65 out of 1. Look at the very end of the graph to look at the conclusion for probability. Similar cases when, after the spinner is spun after 20 times, the probability is 0.65.
Answer:
0.65 or 65%

Part A: Which student simplified the expression incorrectly? Explain the errors that were made or the formulas that were misused. (5 points)
The student that simplified the expression incorrectly is student 2
How to determine the incorrect result?The steps are given as:
[tex]\frac{\cot(\theta) + \tan(\theta)}{\cot(\theta)}[/tex]
Student 1:
Step 1: [tex]\frac{\cot(\theta)}{\cot(\theta)} + \frac{\tan(\theta)}{\cot(\theta)}[/tex]Step 2: [tex]1 + \frac{\tan(\theta)}{\cot(\theta)}[/tex]Step 3: 1 + tan²(Ф)Step 4: sec²(Ф)Student 2:
Step 1: [tex]\frac{\cot(\theta)}{\cot(\theta)} + \frac{\tan(\theta)}{\cot(\theta)}[/tex]Step 2: [tex]\frac{1 + \tan^2(\theta)}{\cot(\theta)/\tan(\theta)}[/tex]Step 3: sec²(Ф)/tan²(Ф)Step 4: csc²(Ф)As a general trigonometry rule;
[tex]\frac{\cot(\theta) + \tan(\theta)}{\cot(\theta)} = \sec^2(\theta)[/tex]
This means that student 1 is correct, while student 2 is not
The first error in student 2's workings is in step 2, where we have:
[tex]\frac{\cot(\theta)}{\cot(\theta)} + \frac{\tan(\theta)}{\cot(\theta)} = \frac{1 + \tan^2(\theta)}{\cot(\theta)/\tan(\theta)}[/tex]
The above expression is not justified and cannot be proved by any trigonometry rule
Since the step 2 is incorrect, the other steps cannot be used.
Hence, the student that simplified the expression incorrectly is student 2

Answer:

Step-by-step explanation:
9 < 5+y
Solve the inequality
Answer:
4<y
Step-by-step explanation:
1st step:9=5+y
2nd step: 9-5=y
3rd step: 4=y
4th step: 4<y
Answer:
y > 4 or 4 < y
Step-by-step explanation:
In this inequality, the < sign, also known as the less than sign, means that 9 is less than the value of 5 + y. Solving inequalities can be simple to do - let's begin!
9 < 5 + y
We know that we must isolate y to determine its value. We can do this by subtracting 5 from both sides of the < sign.
9 - 5 < 5 + y - 5
Simplify!
4 < y → This means that 4 is less than y. Let's rewrite this.
y > 4 → Rewritten, your answer looks like this! This now states that y is greater than 4, which is the same as 4 being less than y.

Answer:
D. 2.19
Step-by-step explanation:
ok so the formula for the surface area of a sphere is 4[tex]\pi[/tex][tex]r^2[/tex]
We see that 4[tex]\pi[/tex][tex]r^2[/tex]=60.
To find the radius we must isolate r on one side of the equations.
[tex]r^2[/tex]=60/4[tex]\pi[/tex]
[tex]r^2[/tex] = 4.77464829276
r = [tex]\sqrt{4.77464829276}[/tex]

Let f(x)=20/5+6e^−0.1x What is (5)? Round your answer to 4 decimal places.
We can conclude that the function evaluated in x = 5 is equal to 2.3150
How to evaluate the function?Here we have the function:
[tex]f(x) = \frac{20}{5 + 6e^{-0.1x}}[/tex]
And we want to evaluate in x = 5, this just means to replace the x by a 5 in the given function:
We can evaluate this with a calculator (as doing it by hand is kinda hard), we will get:
[tex]f(5) = \frac{20}{5 + 6e^{-0.1*5}} = 2.3150[/tex]
So we can conclude that the function evaluated in x = 5 is equal to 2.3150.

Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 27 liters per minute. There are 700 liters in the pond to start.
Let W represent the total amount of water in the pond (in liters), and let I represent the total number of minutes that water has been added. Write an equation
relating W to T. Then use this equation to find the total amount of water after 17 minutes.
Equation:__
Total amount of water after 17 minutes: __liters
Answer: Equation: 27t +700 = w
Total amount of water after 17 minutes: 1159 L
Step-by-step explanation:
Equation: 27t +700 = w
let t = minutes
let w = total amount of water in pond (liters)
Total amount of water after 17 minutes: 1159 L
t = 17
therefore
27(17) +700 = 1159

The angle measures of quadrilateral RSTU are shown.
m∠R = (2x)°
m∠S = (3x – 35)°
m∠T = (x + 35)°
The measure of angle U is unknown. Can quadrilateral RSTU be a parallelogram?
Yes, opposite angles R and T are congruent to each other if x = 35.
Yes, consecutive angles R and S are congruent to each other if x = 35.
No, if x = 35, all three given angles measure 70°. The fourth angle would measure 150°.
No, if x = 35, the three given angle measures make it impossible for the figure to be a quadrilateral.
The quadrilateral RSTU be a parallelogram if opposite angles R and T are congruent to each other if x = 35 option first is correct.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners.
We have:
The angle measures of quadrilateral RSTU are shown.
m∠R = (2x)°
m∠S = (3x – 35)°
m∠T = (x + 35)°
If R and T are congruent:

x = 35 degree
Opposite angles R and T are congruent to each other if x = 35.

Child labor is a service rendered by children in any field during their childhood. This is done due to lack of resources for subsistence, irresponsibility of the parents or lack of resources by the owner to increase their returns on low investment.
This does not matter with the cause of child labor as all the reasons force children to live life without childhood. Childhood is the greatest and happiest period of everyone’s life, during which one learns about the basic strategy of life from parents, loved ones and nature. Child labor interferes with the proper growth and development of children in all aspects, mentally, physically, socially and intellectually.

A. Gus buys cupcakes every Saturday morning. When he walks into the bakery, he always orders by saying, "Give me $10 worth of cupcakes." What does this tell you about Gus's elasticity of demand for cupcakes?
B. Use the graph believe to illustrate Gus’ demand for cupcakes. This line should only contain the two endpoints (X axis is quantity of cupcakes 0-25 going by 5s, Y axis is Price of cupcakes 0-6 going up by 2)
The thing that can be deduced from Gus's elasticity of demand for cupcake is that the demand for cupcakes is perfectly elastic.
What is elasticity of demand?It should be noted that elasticity of demand simply means the responsiveness to demand when there's a change in price.
Gus's elasticity of demand for cupcake is that the demand for cupcakes is perfectly elastic. This is when the percentage change in quantity demanded is infinite due to the price change.
