Since , a researcher is attempting to determine which ethnic group is more likely to go to the movies at a movie theatre. The dependent variable is metric. Therefore, the Multiple Regression method will be more appropriate analysis of variance.

Multiple regression analysis is a statistical technique that analyzes the relationship between two or more variables and uses that information to estimate the value of the dependent variable. The goal of multiple regression is to develop a model that describes the dependent variable y with multiple independent variables. Linear regression has only one independent and dependent variable. But for multiple regression, there are many independent variables that help explain or predict the dependent variable y better.

The multiple regression equation is given by

y = a + b 1×1+ b2×2+……+ bk xk

where x1, x2, ….xk are the k independent variables and y is the dependent variable

The given expression can be simplified as (x³ + 3x + 5)/(x² - x).

If the fractions have the same denominators then their numerators are added keeping the denominators as the same.

For fractions with different denominators the LCM of the denominators are taken then that is divided by the numerators of each fraction and the number obtained is multiplied to each of them to get the equivalent fraction.

The given expression is as below,

(x² - 5)/x + (x + 8)/(x - 1)

It can be simplified as follows,

(x² - 5)/x + (x + 8)/(x - 1)

= ((x² - 5)(x - 1) + x(x + 8))/(x(x - 1))

= ((x³ - x² - 5x + 5) + x² + 8x)/(x² - x)

= (x³ + 3x + 5)/(x² - x)

the value for dferror for this analysis is 8.

What is error?

Error is the difference between an actual value and an estimate, or approximate, representation of that value in applied mathematics. The discrepancy between the population's average and the average of a sample taken from that population is a frequent example in statistics. The discrepancy between an irrational number's true value and the values of rational expressions like 22/7, 355/113, 3.14, or 3.14159 serves as an example of round-off error in numerical analysis. A truncation error happens when an infinite series is ignored for all but a small number of terms. For instance, the sum of the infinite series can be used to express the exponential function ex.

df-error = (df-within treatment) - (df-subjects)

df-subjects = n - 1 = 5 - 1 = 4 {n is the no of subjects}

lines a and d are neither parallel nor perpendicular.

What is the slope of line?

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1). x1 and y1 are represented by the first point's coordinates. The second points are located at x2, y2, and their locations. Whichever point you choose to classify as the first and which as the second doesn't matter.

m1 = -4/ 7

The slope of line d is m2 = [tex]\frac{13-8}{2-5}[/tex]

Under the Binomial and Poisson distributions gives approximate result is p → 0 n → ∞.

One of the common discrete distribution which is used in Statistics is the Binomial distribution. The Binomial distribution often deals with two types of situations, first, the occurring of an event and second, the non-occurring of an event termed respectively as success and failure. The Binomial distribution can be typically characterized by the two parameters namely “n” and “p” where “n” represents the number of trials and “p” represents the fixed probability of occurring of the desired event.

Further, the Binomial distribution can be visualized as an approach to determine the probability of observing a specified number of successes in a specified number of trials. The typical examples of Binomial distribution in our day-to-day life may include the survival of number of cancer patients, from the treatment offered, over a specified period of time;

Winning the number of seats against the number of candidates filed by a certain political party for an election;

Number of people benefiting from a certain house scheme when applied;

Number of covid patients discharged within three days from the hospital after their admission to a hospital for the treatment.

There is another discrete distribution which is equally popular as the Binomial distribution is the Poisson distribution. While the Binomial distribution deals with the number of trials and the probability of a success, Poisson distribution deals with the average number of successes per day or the number of successes observed per unit of time.

Unlike, in the case of a Binomial distribution, for a Poisson distribution, the knowledge of number of trials to get the observed number of successes is not required. The Poisson distribution has only one parameter namely “m” the mean number of successes per given unit of time.

The Poisson distribution is often taken as a limiting case of Binomial distribution, under the following conditions.

The number of trails is indefinitely large i.e., n → ∞

The probability of success, “p” is very small i.e., p → 0

np is finite i.e., np = m where p = m/n and q = 1 – m/n and m > 0.

However, it is not defined if “n” is large means how large and “p” is closed to zero means how small? It is left to the readers to assume how large n should be and how small p should be? As mentioned earlier, the Poisson distribution is often described as a limiting case of Binomial distribution.

Based on the results of the study , published by me clearly proves that even when 10 ≤ n ≤50 and p ≤ 0.2, the Poisson distribution can be a good approximation to Binomial distribution.

Hence the answer is Under the Binomial and Poisson distributions gives approximate result is p → 0 n → ∞.

3.5 * 60 = 210 minutes

Accordingly,

Time (min)            Number of bracelets

30                      ⇒            7

210                    ⇒           x

Now, we can make an expression like this using cross multiplication.

30x = 7 × 210

30x = 1470

Divide both sides by 30.

Fastest: Kaliel, slowest: steve

Step-by-step explanation:

The unit for Melissia can be found by finding the slope of the line. The slope is shown to be 4 miles per hour. That is the unit rate, 4 miles per hour.

The unit rate for steve is also shown in the equation y = 1.5x. This equation is the filled in form of y = mx + b where m is equivalent to the slope. Therefore 1.5 is the slope meaning the unit rate is 1.5 miles per hour.

The unit rate for Kaliel is found using the information that he walks 10 miles in two hours. To find how much he goes in 1 hour divide by two getting you 5 miles per hour.

The fastest unit rate is Kalie with 5 miles per hour, and the slowest steve with 1.5 miles per hour.

The expressions of the total cost are 1.15t and t * (1 + 0.15)

From the question, we have the following parameters that can be used in our computation:

Cost of a ticket = t dollars

Amusement tax on each ticket = 15%

The above parameters mean that the total cost of a ticket can be calculated using the following equation

The total cost of a ticket = Cost of a ticket * (1 + Amusement tax on each ticket)

Substitute the known values in the above equation, so, we have the following representation

The total cost of a ticket = t * (1 + 15%)

Evaluate the percentage

The total cost of a ticket = t * (1 + 0.15)

So, we have

The total cost of a ticket = t * (1.15)

Evaluate the product

The total cost of a ticket = 1.15t

Hence, the expression is 1.15t

The probability that the islanders will win exactly two games is 0.359.

The binomial distribution is based on the binomial theorem which can be written as (a + b)ⁿ = ⁿC₀aⁿb⁰ + ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+ ⁿCₙa₀bⁿ.

In order to use in the probability, there should be events independent of each other and the sum of there probabilities is 1.

Given that,

The probability of winning is 4/7.

Then the probability to lose is 1 - 4/7 = 3/7.

If islanders win exactly two games out of four, it implies that they will lose 2 as well.

Now, the probability of winning exactly two games can be found using binomial distribution as given below,

⁴C₂(4/7)²(3/7)²

= 6 × 16/49 × 9/49

= 864/2401

The amount of time it would take for 20% of the water to leak from a full vase is equal to 24.128 minutes.

Mathematically, the volume of a cone can be calculated by using this formula:

V = 1/3 × πr²h

Where:

From the diagram of the cone (see attachment), we have the following parameters:

Diameter of cone = 4.8 in.

Height of cone = 10 in.

Radius of cone = diameter/2 = 4.8/2 = 2.4 in.

Substituting the given parameters into the formula, we have;

Volume of cone, V = 1/3 × 3.142(2.4² × 10)

Volume of cone, V = 60.32 in³.

For the volume of water that has leaked, we have:

Volume of water leaked = 20/100 × 60.31

Volume of water leaked = 12.062 in³.

For the required amount of time, we have:
