a queuing model that follows the m/m/1 assumptions. a customer can be served every 4 minutes. customers arrive independently at the rate of one customer every 5 minutes according to a poisson distribution. the average number in the system is

Answers

For the m/m/1 queuing model, the average number in the system is equals to the four. So, the correct answer is option (c).

This is the most widely used queuing system in analytics. M/M/1 is a good approximation for a large number of

mass service systems. The M/M/1 quening system assumes a Poisson arrival process. This assumption is a very good approximation for the process of arriving at real systems that satisfy the following rules,

The number of customers in the system is very large.The influence of one customer on system performance is very small, i.e. one customer consumes a very small percentage of system resources.All customers are independent, i.e. their decision to use the system is independent of other users.

We have, customer service is every 4 minutes. So, the Service rate μ = 1 customer/4 minutes = 0.25 customer/minute or 15 per hour.

Customers arrive individually at a rate of one customer every 5 minutes according to the distribution of poisons.

Number of customer service= 1

The arrival rate is 1/ (mean time between arrivals) . Here, the rate of arrival of customers/5 minutes is λ = 0.2 customers/min or 12 per hour. Therefore,

Utilization factor = (arival rate /service rate)100 = λ/μs

Utilization factor = (12/15) 100%

= (4/5)100 = 80%

Utilization factor = 80%

Average number in the system = λ/( μ - λ)

= (60/5)/[ (60/4)-(60/5)]

= 12/3 = 4

So, the average number in the system is 4.

After one rotation of the wheel, how many inches further has the truck with the larger tires traveled
than the truck with the factory-installed (old) tires?

Answers

The distance travelled by larger circular wheel is 2π(R-r) more than the distance travelled by old tires.

What is a circle?

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

The equation of circle in the plane is given as:

(x-h)^2 + (y-k)^2 = r^2

where (x, y) are the coordinate points

(h, k) is the coordinate of the center of a circle

and r is the radius of a circle.

and Area of circle = πr²

Circumference of circle=2πr

Now

let radius of old tires =r

radius of new tires =R

distance travelled by new tire in one rotation= 2πR

distance travelled by old tire=2πr

Hence,

            The distance travelled by larger circular wheel is 2π(R-r)  more than the distance travelled by old tires.

Within a school district, students were randomly assigned to one of two Math teachers - Mrs. Smith and Mrs. Jones. After the assignment, Mrs. Smith had 30 students, and Mrs. Jones had 25 students. At the end of the year, each class took the same standardized test. Mrs. Smith's students had an average test score of 78, with a standard deviation of 10; and Mrs. Jones' students had an average test score of 85, with a standard deviation of 15. Test the hypothesis that Mrs. Smith and Mrs. Jones are equally effective teachers.

Answers

There is enough evidence to conclude that Mrs. Smith and Mrs. Jones are not equally effective teachers.

What are the hypothesis tested?

At the null hypothesis, it is tested if the means are the same, hence:

[tex]H_0: \mu_1 - \mu_2 = 0[/tex]

At the alternative hypothesis, it is tested if the means are different, hence:

[tex]H_0: \mu_1 - \mu_2 \neq 0[/tex]

What are the mean and the standard error for the distribution of differences?

For each sample, the mean and the standard error are given as follows:

Mrs. Smith: [tex]\mu = 78, \sigma = \frac{10}{\sqrt{30}} = 1.8257[/tex]Mrs. Jones: [tex]\mu = 85, \sigma = \sqrt{15}{\sqrt{25}} = 3[/tex]

Hence the mean and the standard error for the distribution of differences are given as follows:

[tex]\mu = 78 - 85 = -7[/tex][tex]\sigma = \sqrt{1.8257^2 + 3^2} = 3.5119[/tex]

What are the test statistic and the conclusion?

The test statistic is given by the division of the mean by the standard error of the distribution of differences, hence:

z = -7/3.5119

z = -1.99.

We have a two-tailed test, as we are testing if the mean is different of a value.

Using a z-distribution calculator, with z = -1.99, and a two-tailed test, the p-value is given as follows:

0.0466.

As the p-value is less than the standard significance level of 0.05, there is enough evidence to conclude that Mrs. Smith and Mrs. Jones are not equally effective teachers.

Answers

The length of the one of the leg of the triangle is 12√2 in. Thus, option B is correct.

What is a hypotenuse?

The longest side of a right triangle in geometry is called the hypotenuse. Moreover, it is the side that faces the right angle. The definition of hypotenuse is "length under" or "stretch under." Plato was said to have used it for the first time around 400 BC.

In many applications of geometry and trigonometry, the hypotenuse plays a significant role. The Pythagorean Theorem is the most widely known. Using the Pythagorean Theorem, a2 + b2 = c2, one can determine the length of the hypotenuse.

The Right angles triangle is also a isosceles angled triangle which means two of the angles are equal.

When two angles are equal the corresponding sides are equal too.

a = b

Given that the measure of the triangles' hypotenuse is 24 inches

c² = a² + b²

24² = a² + b²

576 = a² + b²

But the sides are equal i.e.

a = b

Giving us

576 = a² + a²

576 = 2a²

a² = 576/2

a² = 288

a = √288

a = 12√2

Thus, the length of the one of the leg of the triangle is 12√2 in. Thus, option B is correct.

How many sides does the polygon have?

Answers

The number of sides that the polygon has is given as follows:

24 sides.

How to obtain the number of sides of the polygon?

A regular polygon is a polygon in which all side lengths have the same measure, hence all the internal angles of the polygon will also have the same measure.

The sum of the internal angle measures of a polygon of n sides is given as follows:

S(n) = (n - 2) x 180º.

For a regular polygon of n sides, with n angles of equal measure, the measure of each interior angle is given as follows:

I = (n - 2) x 180/n.

In the case of the center of the polygon, the sum of the internal angles is of 360º, hence the number of sides n can be obtained as follows:

n  = 360/I.

For this problem, the internal angle measure is given as follows:

I = 15º.

Hence the number of sides is calculated as follows:

Answers

Answer: To find the X and Y components of the 15N weight of the birthday cake, we can use trigonometry. We know that the angle of inclination of the table is 23° above the horizontal.

We can use the tangent function to find the X component of the weight, which is the component that is parallel to the table.

X = 15N * tangent (23°)

We can use the sine function to find the Y component of the weight, which is the component that is perpendicular to the table.

Y = 15N * sine (23°)

By applying these formulas and plugging in the angle and weight we can find the respective X and Y components.

Prove that every non-zero element of a finite dimensional vector space over a field has a unique expression as a linear combination of a basis for the space.

Answers

To prove this statement, we will use the following definitions and properties:

A finite dimensional vector space is a vector space that has a finite number of basis vectors.

A basis for a vector space is a set of vectors that span the space, meaning that any vector in the space can be written as a linear combination of the basis vectors.

A linear combination of a set of vectors is an expression of the form a_1v_1 + a_2v_2 + ... + a_nv_n, where v_1, v_2, ..., v_n are the basis vectors and a_1, a_2, ..., a_n are scalars from the field.

A non-zero element of a finite dimensional vector space is a vector that is not equal to the zero vector, the additive identity of the space.

Now, let's assume that V is a finite dimensional vector space over a field F, and let B be a basis for V. We will show that every non-zero element of V can be expressed as a unique linear combination of the basis vectors in B.

Let v be a non-zero element of V. Since B spans V, there exists a set of scalars a_1, a_2, ..., a_n from the field F such that v = a_1v_1 + a_2v_2 + ... + a_nv_n, where v_1, v_2, ..., v_n are the basis vectors in B. This is a valid linear combination representation of v with respect to B.

To show that this linear combination representation of v is unique, let's assume that there exists another set of scalars b_1, b_2, ..., b_n from the field F such that v = b_1v_1 + b_2v_2 + ... + b_nv_n. Then, subtracting the second equation from the first one, we get:

0 = (a_1 - b_1)v_1 + (a_2 - b_2)v_2 + ... + (a_n - b_n)v_n.

Since B is a basis for V, the only way for the left-hand side of the equation to be the zero vector is for all the scalars in the linear combination to be equal, i.e. a_1 = b_1, a_2 = b_2, ..., a_n = b_n. Thus, v can be expressed as a unique linear combination of the basis vectors in B, which completes the proof.

Difference between synthetic division and synthetic substitution

Answers

Answer: Synthetic division and synthetic substitution are both methods used to divide polynomials, but they are used for different types of polynomials and have different steps and procedures.

Synthetic division is a method used to divide a polynomial by a linear binomial of the form (x-c), where c is a constant. It is used to find the quotient and remainder of the division, and it involves a process of simplifying the polynomial using a specific set of steps.

Synthetic substitution, on the other hand, is a method used to divide a polynomial by a polynomial of higher degree. It is used to find the quotient and remainder of the division, and it involves replacing a variable in the polynomial with an expression and then simplifying.

In summary, Synthetic Division is used when dividing a polynomial by a linear binomial and Synthetic Substitution is used when dividing a polynomial by a polynomial of higher degree.

Step-by-step explanation:

Synthetic division is used for polynomial division by a linear factor, resulting in a quotient polynomial. Synthetic substitution, however, is used to find the value of a polynomial function at a given x-coordinate.

Synthetic division and synthetic substitution are both methods used in algebra to evaluate polynomials. However, they differ in their specific applications and the outcomes they provide.

Synthetic division is a method used to divide a polynomial by a linear factor of the form (x - c). It allows for quick and efficient division without the need for long division. The process involves setting up a synthetic division table and performing a series of calculations based on the coefficients of the polynomial. The result is a simplified quotient polynomial.

On the other hand, synthetic substitution is a technique used to evaluate a polynomial function at a specific value of x. It involves substituting the given value into the polynomial and using synthetic division to perform the calculations. The result obtained is the value of the polynomial at that particular x-coordinate.

Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.

In the triangle, we have angles of 30° and 90°

Using trigonometric ratios:

sin 30° = (2p+1)/(6p-10)     [sin = opp/hyp]

1/2 = (2p+1)/(6p-10)

1/2(6p-10) = (2p+1)

3p -2p = 1+5

p = 6 units

cos 30° = w/(6p-10)       [cos = adj/hyp]

(√3)/2 = w/(6p-10)

(√3)/2 = w/((6×6) -10)

Solve the right triangle if the hypotenuse is 5 and one acute angle is 34°. Round answers to two decimal places.

Answers

i. α = 56°

ii. adj =  4.1

iii. opp = 2.79

What is the right angle triangle?

We have to recall that what makes the right angle triangle unique is the fact that one of the angles that we find in the triangle is 90 degrees. We have to recall that the sum of the angles that we have in a triangle is 180°.

Hence we have;

α = 180 - (90 + 34)

α = 56°

Then;

Cos 34 = adj/5

adj = 5 cos 34

= 4.1

Sin 34 = opp/5

opp = 5 * sin 34

= 2.79

These are the parts of the right angled triangle required.

For the following two numbers, find two factors of the first number such that their product is the first number and their sum is the second number.

28,16

Answers

The two factors of the first number 28 that their sum is will be equal to the second number 16 are 2 and 14.

Factor of a number

Factor is a number that divides another number without a remainder. That is if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product.

The first number 28 have the following factors:

1, 2, 4, 7, 14, and 28.

the factors 2 and 14 are the factors we need because;

2 × 14 = 28

2 + 14 = 16

Therefore, 2 and 14 are the two factors of 28 that their product is the first number 28 and their sum is the second number 16.

evaluate the iterated integral. 1 0 s6 cos(s7) dt ds 0

Answers

The value of the evaluated iterated integral is 0.1202.

As per the given data the iterated integral is [tex]I & =\int_0^1 \int_0^{s^6} \cos \left(s^7\right) d t d s[/tex].

Here we have to evaluate the given iterated integral.

The definite integral of a real-valued function f(x) with respect to a real variable x on an interval [a, b] is expressed as[tex]$\int_a^b f(x) d x$[/tex] = F(b) - F(a)

Here,

[tex]$\int=$[/tex] Integration symbol

a = Lower limit

b = Upper limit

f(x) = Integrand

dx = Integrating agent

Thus, [tex]$\int a b f(x) d x$[/tex] is read as the definite integral of f(x) with respect to d x from a to b.

Indefinite integrals are implemented when the boundaries of the integrand are not specified.

[tex]I & =\int_0^1 \int_0^{s^6} \cos \left(s^7\right) d t d s[/tex]

Integrate the given iterated integral.

We get:

[tex]& =\int_0^1 \cos \left(s^7\right)\left(\int_0^{s^6} d t\right) d s[/tex]

[tex]& =\int_0^1 \cos \left(s^7\right) \times[t]_0^{s^6} d s . \\[/tex]

[tex]& =\int_0^1 \cos \left(s^7\right) \times\left(s^6-0\right) d s . \\[/tex]

[tex]& =\int_0^1 s^6 \cos \left(s^7\right) d s[/tex]

Say [tex]s^7=t[/tex]                 when s = 0

[tex]\Rightarrow \frac{d t}{d s}=7 s^6 \quad$[/tex]                          t = 0  

[tex]\Rightarrow \frac{d t}{7}=s^6 d s[/tex]              when s = 1.....   t = 1

Replace the assumed terms.

Then we get:

[tex]$I=\int_0^1 \cos (t) \frac{d t}{7}$[/tex]

[tex]$=\frac{1}{7} \int_0^1 \cos (t) d t$[/tex]

[tex]$=\frac{1}{7}[\sin (t)]_0^1=\frac{1}{7}[\sin (1)-\sin (0)]$[/tex]

[tex]=\frac{\sin (1)}{7}$[/tex]

[tex]\int_0^1 \int_0^{s^6} \cos \left(s^7\right) d t d s[/tex] = 0.1202

Every day your heart creates enough energy to drive a truck for 32 kilometers. If you combined the energy created all the students in your math class for a week, how many meters could the truck drive?
PLEASE SHOW FULL WORK:>

Answers

To calculate the total amount of energy created by all the students in your math class for a week, we need to first determine the number of students in the class and then multiply that by the amount of energy created by one person's heart per day.

Let's assume there are 20 students in the math class.

To find the distance the truck could drive with all the students' energy, we need to multiply the energy created by one person's heart per day by the number of students in the class and then by the number of days in a week.

1 student's energy per day = 32 km
Number of students = 20
Number of days in a week = 7

So the total distance the truck can drive with the energy created by all students in the class is:

32 km x 20 students x 7 days = 4480 km

To convert this to meters, we can use the conversion factor 1 km = 1000 meters.

So the total distance the truck can drive with the energy created by all students in the class is:
4480 km x 1000 m/km = 4,480,000 meters

So, the truck could drive 4,480,000 meters if the energy created by all students in a math class for a week is combined.
