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.

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:

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.

Answer + Step-by-step explanation:

p(X=3) = the probability that X is equal to 1 or 2 or 3 minus (the probability that X is equal to 2 plus the probability that X is equal to 1)

Answer:

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.

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

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.

All of this creates the equation: 5x + 18 = y.

Next, we can do the same to find Tom's equation.

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.

4x + 18 = 30

4x = 12

x = 3

This means after 3 months the number CDs will be equal.

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.

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.
