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

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 equation of circle for both the parts will be as,

(a)  (x-3)² +(y-2)²= 4

(b)   x²+y² = 1

What is circle?

A circle may be a form consisting of all purposes in a very plane that ar at a given distance from a given point, the centre. Equivalently, it's the curve copied out by a point that moves in a very plane so its distance from a given point is constant.

Main Body:

(a) When the circle is offset from the origin, the equation for the radius gets messy. In general, it will be the root of a quadratic equation in sine and cosine, not easily simplified. The Cartesian equation is easier to write.

Circle centered at (h, k) with radius r:

(x -h)² +(y -k)² = r²

The given circle is ...

(x -2)² +(y -2)² =2²

(x -2)² +(y -2)² = 4

__

(b) When the circle is centered at the origin, the radius is a constant. The desired circle is most easily written in polar coordinates:

x²+y² = 1

Hence the equation of circle is such.

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 → ∞.

We can prove that the given triangles GHL and KHJ are congruent using the ASA theorem. So, the second option is the correct answer.

We can say any two shapes are congruent if they have the same shape and size. For this, their sides and angles need to be mirror images of each other. We have four congruency theorems at hand here. These are side-side-side(SSS), angle-side-angle(ASA), side-angle-side(SAS), and angle-angle-side(AAS).

According to the ASA congruency theorem, one side and two angles of the triangles in question need to be similar. In the given image, we can see that two of the angles i.e., HGL and HKJ are congruent while GHL and KHJ are congruent. The sides GH and KH are also congruent. This makes the two triangles  △GHL ≅ △KHJ by the ASA theorem. So, the second option is the correct answer.

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 year in which the number of both jobs pharmacy technicians and network systems and data communication analysts is equal is 2008.

Considering the set of equations

7.3x - y = -256

12.1x - y = -234

where x represents the period of time since 2003.

y represents the quantity of jobs in thousands.

We have the answer after solving the system:

(x, y) ==> (4.5, 292)

Find the year where the total number of both jobs is equal.

At the solution point, the graphs of the two lines will collide.

The year in which the number from both jobs is equal will be 4.5 years after 2003, since x is the number of years after 2003.

So, here we are:

Year where the sum of the two jobs is equal:

2003 + 4.5 = 2007.5

= 2008 year

As a result, there will be an equal number of both jobs in 2008.

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.

The given points of line d is (3,5) and (10,1)

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.
