The assumptions of a normal population distribution and a randomly selected sample are required in order to make valid statistical inferences.

To explain further, the assumption of a normal population distribution means that the values in the population follow a bell-shaped curve. This assumption is important because many statistical tests and procedures are based on the assumption of normality. It allows us to make accurate predictions and draw conclusions about the population based on the sample data.

The assumption of a randomly selected sample means that every individual in the population has an equal chance of being included in the sample. This is important because it helps to ensure that the sample is representative of the entire population. Random sampling helps to minimize bias and increase the generalizability of the findings to the population as a whole.In summary, the assumptions of a normal population distribution and a randomly selected sample are both required and must be satisfied in order to make valid statistical inferences.

There is a 1.13 probability that Meleah will have to wait 5 minutes or less to see one of the courtesy vans from either car rental company A or B.

We can take into account the arrival times of the courtesy vans provided by both companies to determine the likelihood that Meleah will have to wait no more than five minutes to see one of the vans.

The courtesy van comes to car rental company A every seven minutes. This indicates that Meleah will see the van one in seven times within the first minute, one in seven times in the second minute, and so on.

Similar to this, the courtesy van comes to Car Rental Company B every 12 minutes. As a result, Meleah's chance of seeing the van in the first minute is one in twelve, her chance of seeing it in the second minute is one in twelve, and so on.

We need to add up the probabilities for each minute for both businesses and make sure that it does not exceed 1 in order to determine the likelihood that Meleah will see one of the vans within the next five minutes. The equation is as follows:

Probability for business A: 1/7, 1/7, 1/7, and 1/7) equals a probability of 5/7 for company B: 1/12 + 1/12 + 1/12 + 1/12) = 5/12 To determine the total probability, we add the probabilities of the two businesses:

To find the expected value (E(x)) for one play of the game, we need to calculate the average amount per game the player can expect to lose.

In American roulette, the player bets $1 on a number and either wins or loses. There are 38 numbers on the wheel, including 0 and 00. Since the player wins $36 when their chosen number hits, and loses $1 when it doesn't, we can calculate the probability of winning and losing.

The probability of winning is 1/38 because there is only one winning number out of 38 total numbers. The probability of losing is 37/38 because there are 37 losing numbers out of 38.

To calculate the expected value, we multiply the possible outcomes by their respective probabilities and sum them up:

E(x) = (Probability of winning * Amount won) + (Probability of losing * Amount lost)
     = (1/38 * $36) + (37/38 * -$1)

The two equations x + 3y = 5 and 4x + 12y = 20 represent a system of linear equations.

To solve this system, we can use the method of substitution. Let's begin by solving the first equation for x in terms of y:

x + 3y = 5

Subtract 3y from both sides:

x = 5 - 3y

Now, substitute this expression for x into the second equation:

4x + 12y = 20

Replace x with 5 - 3y:

4(5 - 3y) + 12y = 20

When two planes are equidistant from the center of a sphere and intersect the sphere, they form circles on the surface of the sphere. These circles are not lines in spherical geometry, but rather curves that are parallel to each other and do not intersect.

Two planes that are equidistant from the center of a sphere and intersect the sphere will form circles on the surface of the sphere. These circles are not lines in spherical geometry.

In spherical geometry, a line is defined as the intersection of a plane with the sphere.

However, in this case, the planes are not intersecting the sphere at a single point, but instead intersecting it along a curve. This curve forms a circle on the surface of the sphere.

To understand this concept better, let's consider an example. Imagine a sphere representing the Earth and two planes that are equidistant from its center.

These planes could represent different latitudes on the Earth's surface. When these planes intersect the Earth, they will form circles that correspond to the latitudes. These circles are parallel to each other and do not meet.

In contrast, if we consider a line in spherical geometry, it would be a great circle on the surface of the sphere. A great circle is a circle that has the same center as the sphere itself and divides the sphere into two equal halves.

Examples of great circles on Earth are the equator and any line of longitude.

So, to summarize, when two planes are equidistant from the center of a sphere and intersect the sphere, they form circles on the surface of the sphere.

To solve the equation x⁵ - 5x³ + 4x = 0, we can factor out an x from each term. This gives us x(x⁴ - 5x² + 4) = 0. Now we have two factors: x = 0 and x⁴ - 5x² + 4 = 0.

To solve x⁴ - 5x² + 4 = 0, we can make a substitution by letting y = x². This gives us y² - 5y + 4 = 0. We can then factor this quadratic equation as (y - 4)(y - 1) = 0.

Setting each factor equal to zero, we have y - 4 = 0 and y - 1 = 0. Solving these equations, we find y = 4 and y = 1.

Now, we substitute back y = x² to find the values of x. For y = 4, we have x² = 4, which gives us x = ±2. For y = 1, we have x² = 1, which gives us x = ±1.

The change in fuel and distance can be analyzed through the slope of the line in the table, which indicates the rate of fuel consumption per mile. A slope of 0.4 suggests that 0.4 gallons of fuel are being consumed for every mile traveled.

The change in fuel remaining from one row to the next in the table represents the difference in the amount of fuel used between those rows. This change is measured in gallons. For example, if the fuel remaining in one row is 10 gallons and in the next row it is 8 gallons, the change in fuel remaining would be 2 gallons.

Similarly, the change in distance from one row to the next in the table represents the difference in the distance traveled between those rows. This change is measured in miles. For instance, if the distance traveled in one row is 50 miles and in the next row it is 45 miles, the change in distance would be 5 miles.

The slope of the line that runs through the points given in the table represents the rate of change between the fuel remaining and the distance traveled. It is calculated by dividing the change in fuel by the change in distance. For example, if the change in fuel is 2 gallons and the change in distance is 5 miles, the slope would be 2/5 or 0.4.

The slope indicates the rate at which fuel is being consumed per mile. In this case, a slope of 0.4 means that for every mile traveled, 0.4 gallons of fuel are being used. This implies that the vehicle's fuel efficiency is 0.4 gallons per mile.

By adding 3x to both sides of the equation, we perform the operation of balancing the equation. This operation ensures that the equation remains balanced, as whatever is done to one side of the equation must also be done to the other side to maintain equality.

So, adding 3x to both sides of Equation (1) yields Equation (2):

x + 9 + 3x = 4 - 3x + 3x

Simplifying Equation (2) further:

4x + 9 = 4

Now, Equation (2) is simplified and in a form where x can be easily solved or further manipulated if needed.

The operation of adding 3x to both sides of Equation (1) is used to transform it into Equation (2). This step is taken to isolate the variable x on one side of the equation and simplify the equation for further analysis or calculations.
