Use the regression line for the data in the scatterplot to answer the question. on average, how many more goals will a player score for every additional hour of practice?
Answers
On average the more goals will a player scores for every additional hour of practice is 3/4.
Given a regression line for the data in the scatterplot which is shown in figure.
This question can be solved by finding the slope of the line.
Slope is the ratio of vertical change to horizontal change between two points on the line.
Here, we can find the slope by taking the two points which is on the line.
Let us take the two points be A(1.5,2) and B(6.5,6)
Now, we will find the slope using the formula, we get
m=(y₂-y₁)/(x₂-x₁) where (x₁,y₁)=(1.5,2) and (x₂,y₂)=(6.5,6)
Substitute the values in the formula, we get
m=(6-2)/(6.5-1.5)
m=4/5
The slope which we find is near to the slope 3/4.
Hence, the more goals will a player score for every additional hour of practice from the regression line is 3/4.

Explain when the solution set of an inequality will be the empty set or the set of all real numbers. Show an example of each.
Answers
Answer:
There are two cases when the solution set of an inequality will be the empty set or the set of all real numbers.
The first case is when the inequality is always false no matter what value is chosen for the variable. For example, the inequality x > 5 has no solution because there is no value of x that is greater than 5. In this case, the solution set is the empty set.
The second case is when the inequality is always true no matter what value is chosen for the variable. For example, the inequality x > -∞ has infinitely many solutions because there is no value of x that is not greater than -∞. In this case, the solution set is the set of all real numbers.

Explain how to find a line perpendicular to a linear function that passes through a given point.
Answers
Answer:
The required line can be found by substituting the slope and the given point in the slope intercept form of a line and is given by y=mx+c, where m is the slope and c is the y intercept.
Step-by-step explanation:
In the given question, it is given that a linear function passes through a given point.It is required to find a line perpendicular to the function.When two functions are perpendicular, the product of their slopes is equal to -1.Thus, substitute the slope and the given point in the slope intercept form of a line and is given by y=mx+c, where m is the slope and c is the y intercept.The equation of a parallel line to a linear function that passes through a point can be explained using the examples below.
We have,
The parallel line to a linear function that passes through a point can be explained using the examples below.
Example:
Let's find a line parallel to the linear function y = 3x - 2 that passes through the point (2, 5).
Step 1: Given linear function and point
Linear function: y = 3x - 2
Point: (2, 5)
Step 2: Determine the slope of the given linear function
The slope (m) of the given function y = 3x - 2 is 3.
Step 3: Use the slope to find the equation of the parallel line
Since the parallel line has the same slope (3), its equation will be
y = 3x + b, where "b" is the y-intercept that we need to find.
Step 4: Substitute the coordinates of the given point into the equation of the parallel line
Using the coordinates (2, 5) of the given point, we can solve for "b":
5 = 3(2) + b
5 = 6 + b
b = 5 - 6
b = -1
So, the equation of the line parallel to y = 3x - 2 and passing through the point (2, 5) is:
y = 3x - 1.
Thus,
The equation of a parallel line to a linear function that passes through a point can be explained using the examples above.

A company produces packets of soap powder labeled Giant Size 32 Ounces. The actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz. and a standard deviation of 0.7 oz. To avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. To avoid losing money, it labels the top 5% (the heaviest 5%) overweight. How heavy does a box have to be for it to be labeled overweight
Answers
In order to be labeled overweight the weight of box should be of 34.15 ounces.
Given mean of 33 ounces, standard deviation=0.7 ounces. Production of packets of 32 ounces.
Because it is normally distributed samples are solved using the z score formula.
In this Z=X-meu/st
meu is sample mean and st is population standard deviation.
We have to find the z score and then p value from the z table.
meu =33 and st=0.7
Top 5% so X when Z has a p value of 1-0.05=0.95. So X when Z=1.645.
Z=(X-meu)/st
1.645=(X-33)/0.7
X-33=0.7*1.645
X-33=1.1515
X=1.1515+33
X=34.1515 ounces.
Hence to be labeled overweight the box must have 34.15 ounces weight.

Tom has a collection of 30 CDs and Nita has a collection of 18 CDs. Tom is adding 1 CD a month to his collection while Nita is adding 5 CDs a month to her collection. Write a system to find the number of months after which they will have the same number of CDs. Let x represent the number of months and y the number of CDs.
Answers
Answer:
3 months
Step-by-step explanation:
Let x be the number of months CDs are added at Tom and Nita's respective rates of 1 and 5 CDs/month.
Tom's collection after x months is = 30 + 1x
Nita's collection after x months is = 18 + 5x
At some point they will have equal numbers of CD's, so set the equations equal to each other:
30 + 1x = 18 + 5x
4x = 12
x = 3 months
At 3 months both Tom and Nita will have the same number of CDs.
Tom: 30 + 1*3 = 33 CDs
Nita: 18 + 5*3 = 33 CDs
x = 3
Step-by-step explanation:We can create a system of equations to represent the situation we have been given.
Creating the Equations
In this system, we can create an equation to represent both people's collections.
First, we can create Nita's.
To create the equation we can start with the constant. We are told she starts with 18 CDs. So, this will be one of the terms.Next, we can multiply x by 5. We can do this because x represents the number of months that have passed and 5 is the number of CDs she adds per month. This means 5x will be another term.Finally, the constant and variable will add up to the total number of CDs, which is represented by y. So, the expression will be set equal to y.All of this creates the equation: 5x + 18 = y.
Next, we can do the same to find Tom's equation.
Tom starts out with 30 CDs. So this will be the constant term.Each month he adds 1 CD. This means that we can multiply 1 by x to make the term 1x.Finally, like with Nita's this expression will be set equal to y.This creates the second equation: 1x + 30 = y.
The system is:
5x + 18 = y
1x + 30 = y
Solving the System of Equations
One method to solve a system of equations is substitution. Substitution is when you substitute an expression for a variable. Since both expressions are set equal to y, we can substitute the expressions for y and set them equal to each other.
This creates the new equation: 5x + 18 = 1x + 30. Then, solve normally.
First, subtract 1x from both sides4x + 18 = 30
Next, subtract 18 from both sides.4x = 12
Finally, divide both sides by 4x = 3
This means after 3 months the number CDs will be equal.

Total service charge of Preston = Total bill - Service Call Charge
= B - S
∴ Number of hours Preston took to mend the broken pipe is given by,
H = (B - S)/P
H = $(120 - 50)/$5
H = 70/5

What does it mean to "model with mathematics"?
Answers
Answer:
See below. To model with mathematics is to test ideas using math and computer programs to simulate an object or action.
Step-by-step explanation:
To "model with mathematics" means that equations and mathematical relationships will be employed to simulate an object or action instead of using the actual object or action. One example would be the design of a roller coaster. The forces inherent on a roller coaster design can be predicted using Newton's laws and other principles of physics. F=ma may be used to predict the force pulling the car down the initial incline and that can be used to calculate speed at the bottom. A change in the car's direction will also produce forces that may be calculated, One might ask "Will this turn produce more force than the seat belt can safely handle?" Rather than building a coaster and testing it with your business partner in the seat, a mathematical model can be used to determine the risks and maximum forces. You'll have a much better chance of keeping your friend intact on the actual coaster. Mathematical models are also used to predict weather, the impact of monetary policy of the economy, and even which Netflix movie you are most likely to enjoy. The design of aircraft, ships, cars, and many other items are done using computer-aided design programs where the various forces can be modeled to determine optimum design without actually building the item. This can save enormous amounts of time and money to be able to test ideas on the computer before starting actual assembly.

Kiera pulls at an angle of 30below the horizontal and with a force of 80 poundsNathan pulls at an angle of 50 degrees above the horizontal and with a force of 85 pounds. The diagram on the right shows the triangle that represents this situation . What is the magnitude of the resultant force acting on the box ?
Answers
Answer:
165.0
30 plus 50 plus the 85 equals 165
The magnitude of the resultant force acting on the box is 126.4 pounds.
Hence the correct answer is C.
Given that Kiera pulls at an angle of 30below the horizontal and with a force of 80 pounds Nathan pulls at an angle of 50 degrees above the horizontal and with a force of 85 pounds.
We need to determine the magnitude of the resultant force acting on the box.
To find the magnitude of the resultant force acting on the box, we can use the law of cosines.
The law of cosines states that for any triangle with sides of lengths a, b, and c, and an angle θ opposite to side c, the following equation holds:
c² = a² + b² - 2ab × cos(θ)
In this case, we have a triangle formed by the two forces exerted by Keira and Nathan, and we want to find the magnitude of the resultant force, which corresponds to side c.
Let's assign the following values:
a = 80 pounds (force exerted by Keira)
b = 85 pounds (force exerted by Nathan)
θ = 180° - 30° - 50° (angle opposite to the resultant force)
θ = 100°
Now we can plug these values into the law of cosines equation:
[tex]F = \sqrt{80^2 + 85^2 -2\times 80 \times 85\times \cos100}[/tex]
Solving we get,
F = 126.4
Hence the magnitude of the resultant force acting on the box is 126.4 pounds.
