How many integers greater than 5400 have both of the following properties :
a) the digits are distinct.
b) the digits 2 and 7 do not occur,

Answers

Answer 1

There are 94830 integers greater than 5400

At first, go it looks .like an infinite number but As digits are distinct

so a maximum 10 digits number is possible

but 2 & 7 can not be used so the maximum 8-digit number can be there

Total number = 4 digits numbers, 5 Digits numbers, 6 digits number, 7 digits numbers, 8 digits numbers

All the 5 - 8 digit numbers would  be > 5400

Available number of Digits = 8  ( 0, 1, 3, 4, 5, 6, 8, 9)

for numbers greater than 4 digits (5 - 8 Digits),  1st  digit can be  1, 3, 4, 5, 6, 8, 9 then from the 2nd digit onward 0 can also be a digit but the already used digit can not be used. and further one digit (already used) will keep reducing

5  Digits numbers = 7 * 7 * 6  * 5 * 4  = 5880

6 Digit Numbers =  7 * 7 * 6  * 5 * 4 *3 =  17640

7  Digits numbers = 7 * 7 * 6  * 5 * 4*2  = 35280

8 Digit Numbers =  7 * 7 * 6  * 5 * 4 *3*2*1 =  35280

Now in 4-digit numbers

Number starting with 6, 8, 9   > 5400   & number starting with 5

Number starting with 6 , 8 , 9 = 3 * 7 * 6 * 5 = 630

Number starting with 5, the second digit must be 4, 6, 8, 9

Number starting with 5 = 1 * 4* 6 * 5 = 120

Total integers greater than 5400

=5880 + 17640 + 35280 + 35280 + 630 + 120

= 94830

A company offers ID theft protection using leads obtained from client banks. Three employees work 40 hours a week on the leads, at a pay rate of $18 per hour per employee. Each employee identifies an average of 4,000 potential leads a week from a list of 4,800. An average of 7 percent of potential leads actually sign up for the service, paying a one-time fee of $90. Material costs are $1,300 per week, and overhead costs are $8,800 per week.

Calculate the multifactor productivity for this operation in fees generated per dollar of input.(Round your answer to 2 decimal places.)

Answers

The multifactor productivity for a given operation is 6.16 fees generated per dollar of input.

What is Break Even Point?

The Break Even Point, or the inflection point at which a corporation starts to make a profit, is the amount of output required for a company's revenue to equal its total costs.

First, we need to calculate the revenue generated per week:

Potential leads per week = 3 employees x 4,000 leads/employee/week = 12,000 leads/week

Actual sign-ups per week = 12,000 leads/week x 7% = 840 sign-ups/week

Revenue per week = 840 sign-ups/week x $90/sign-up = $75,600/week

Next, we need to calculate the input costs per week:

Labor cost per week = 3 employees x $18/hour x 40 hours/week/employee = $2,160/week

Material cost per week = $1,300/week

Overhead cost per week = $8,800/week

Total input cost per week = $2,160/week + $1,300/week + $8,800/week = $12,260/week

Finally, we can calculate the multifactor productivity:

Multifactor productivity = Revenue per week / Input cost per week = $75,600/week / $12,260/week = 6.16

So the multifactor productivity for this operation is 6.16 fees generated per dollar of input.

What is the difference between part-to-part and part-to-whole ratios?

A part-to-whole ratio compares a part to the total of all parts. For example, if you have 100 apples and you want to know what percentage of them are red, you would express the number of red apples as a ratio of the total number of apples. In this case, 10 red apples would be expressed as a ratio of 10:100

A part-to-part ratio compares two or more quantities in terms of their relative sizes. For example, if you have 100 apples and you want to know how many more red apples than green apples you have, you would express the number of red apples and the number of green apples as a ratio of each other. In this case, if you have 30 red apples and 20 green apples, the ratio would be 30:20

Find an equation of a circle that satisfies the given conditions. Center at the origin, passes through (7, 8)

Answers

The equation of a circle whose center is at the origin and passes through (7, 8) is x² + y² = 113

Circle is a round geometry whose all points constitute form a path having a constant distance (radius) from a fixed point (center of the circle).

The standard form for the equation of a circle is (x − h)² + (y − k)² = r², where (h,k) is the center of the circle, and r is the radius.

Center = (h,k) = (0,0)

Point = (7,8)

Now we input those values into the equation:

(x − h)² + (y − k)² = r²

(x − 0)² + (y − 0)² = r²

x² + y² = r²

Next, we have to determine the radius. It can be done by applying Pythagoras' Theorem. Look at the picture:

x² + y² = r²

7² + 8² = r²

49 + 64 = r²

113 = r²

Then we go back to the previous equation, and we get:

x² + y² = r²

x² + y² = 113

Thus, the equation of a circle whose center is at the origin and passes through (7, 8) is x² + y² = 113

Answers

The domain restriction for f(x)/g(x) is x ≠ 0 or -3

How to find the domain restriction  for f(x)/g(x)?

The domain of a function is the set of all input values (or "independent variable") for which the function is defined and produces a valid output (or "dependent variable").

In other words, it is the set of all valid input values for which the function will produce a real output and not give an error or undefined result.

But the domain restriction is the set of values that are not allowed as input for the function.

f(x)/g(x) = (x+26)/(14x²+42x)

In order to find the Domain restriction for f(x)/g(x), equate the denominator g(x) to zero and solve for x. That is:

14x²+42x = 0

14x(x + 3) = 0

14x = 0 or x + 3 = 0

x = 0 or x = -3

Thus, the Domain restriction is x ≠ 0 or -3

The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 51 ounces and a standard deviation of 10 ounces.

Answers

Answer: The statement given tells us that the Acme Company manufactures widgets and that the distribution of widget weights is bell-shaped. A bell-shaped distribution is also known as a normal distribution or a Gaussian distribution. This means that the majority of the data will cluster around the mean (average) value and the farther the data is from the mean, the less common it is.

The mean weight of the widgets is given as 51 ounces, which is the average weight of all the widgets manufactured by the company. The standard deviation is given as 10 ounces, which is a measure of how spread out the data is from the mean. A smaller standard deviation means that the data is more tightly clustered around the mean, while a larger standard deviation means that the data is more spread out.

This information allows us to make some predictions about the weights of the widgets. For example, we know that approximately 68% of the widgets will weigh between 41 ounces (mean - standard deviation) and 61 ounces (mean + standard deviation). Additionally, we know that approximately 95% of the widgets will weigh between 31 ounces (mean - 2standard deviation) and 71 ounces (mean + 2standard deviation) and 99.7% of the widgets will weigh between 21 ounces (mean - 3standard deviation) and 81 ounces (mean + 3standard deviation).

It is important to note that these predictions are based on the assumption that the distribution of widget weights is indeed bell-shaped. If that assumption is not true, these predictions may not be accurate.

It is only specified that 1538 had the protein for normal patients, CFS, and post-treatment Lyme disease; 1884 had the protein for CFS and Lyme; 408 had the protein for CFS only; 2602 had the protein for CFS; 1731 had the normal protein as well as the one for Lyme; 2798 had the protein for Lyme; 2516 had the normal protein. Based on this information, it is not possible to know how many patients had none of the proteins.

Answer: There are no patients who had none of the proteins.

Step-by-step explanation: Part 1

(a) There were 408 patients who only had the protein for Lyme.

This information can be inferred from the data given: 1884 had the protein for CFS and Lyme, and 2798 had the protein for Lyme. If we subtract 1884 from 2798, we get 914 which is the number of patients who only had the protein for Lyme.

Part 2

(b) There were 2516 patients who only had the normal protein.

This information can be inferred from the data given: 1538 had the protein for normal patients, CFS, and post-treatment Lyme disease, 1884 had the protein for CFS and Lyme, and 2602 had the protein for CFS. If we add 1538, 1884 and 2602, we get 6124, then if we subtract 6124 from the total number of patients (3991) we get 2516 patients who only had the normal protein.

Part 3

(c) There were 0 patients who had none of the proteins.

This information can be inferred from the data given: 1538 had the protein for normal patients, CFS, and post-treatment Lyme disease, 1884 had the protein for CFS and Lyme, 408 had the protein for CFS only, 2602 had the protein for CFS, 1731 had the normal protein as well as the one for Lyme, 2798 had the protein for Lyme, and 2516 had the normal protein.

(2002,

Answers

The sum of all the paintable integers is 757.

Note that it is impossible for any of h,t,u to be 1, since then each picket will have been painted one time, and then some will be painted more than once.

h cannot be 2, or that will result in painting the third picket twice. If h=3, then t may not equal anything not divisible by 3, and the same for u. Now for the fourth and fifth pickets to be painted, t and u must be 3 as well. This configuration works, so 333 is paintable.

If h is 4, then t must be even. The same for u, except that it can't be 2 mod 4. Thus u is 0 mod 4 and t is 2 mod 4. Since this is all mod 4, t must be 2, and u must be 4, in order for 5,6 to be paintable. Thus 424 is paintable.

h cannot be greater than 4, since if that were the case then the answer would be greater than 999, which would be impossible for the AIME.

Therefore, the sum of all paintable numbers is 757.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].

The parameters for the binomial distribution in this problem are given as follows:

p = 0.13, n = 300.

Hence the mean and the standard deviation are given as follows:

[tex]\mu = 300 \times 0.13 = 39[/tex][tex]\sigma = \sqrt{300 \times 0.13 \times 0.87} = 5.82[/tex]

Using continuity correction, the probability of X between 33 and 45 is (32.5 < X < 45.5), which is the p-value of Z when X = 45.5 subtracted by the p-value of Z when X = 32.5, hence:

X = 45.5:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (45.5 - 39)/5.82

Z = 1.12

Z = 1.12 has a p-value of 0.8686.

X = 32.5:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (32.5 - 39)/5.82

Z = -1.12

Z = -1.12 has a p-value of 0.1314

The graph of a cubic polynomial function
has horizontal tangent lines at (1, −2) and (−1, 2). Find
an equation for the function and sketch its graph.

Answers

Answer: A cubic polynomial function has the form f(x) = ax^3 + bx^2 + cx + d.

A horizontal tangent line is a line that is parallel to the x-axis and it occurs at a critical point of the function, where the derivative of the function is 0.

We know that a cubic function has 3 critical points and thus 3 derivative that could be 0, so to find the equation of the cubic function we will use these two points to find the value of a, b, c, and d.

We know that the critical points of a cubic function are found by solving f'(x) = 0, where f'(x) is the derivative of the function, so we have:

f'(x) = 3ax^2 + 2bx + c = 0

Now we can use the two points to find the value of a, b, c, and d.

We know that the point (1,-2) is on the graph of the function, so we can substitute it into the equation to find d:

f(1) = a + b + c + d = -2

And we know that the point (-1,2) is on the graph of the function, so we can substitute it into the equation to find d:

f(-1) = -a + b - c + d = 2

Now we can use these two equations to find the value of a, b, and c:

a + b + c + d = -2

-a + b - c + d = 2

2a + 2d = 0

a = -d

-a + b - c + d = 2

b - c = 4

3ax^2 + 2bx + c = 0

3(-d)x^2 + 2bx - c = 0

Now we can use these equations and the critical points to find the value of a, b, c, and d

3(-d)x^2 + 2bx - c = 0, (1,-2) => 3d+2b-c = 0

3(-d)x^2 + 2bx - c = 0, (-1,2) => 3d-2b+c = 0

b-c = 4

Solving these equations, we have:

a = -1/3

b = 1

c = -5/3

d = -2

And the equation for the function is:

f(x) = -1/3x^3 + x^2 - 5/3x - 2

We can now sketch the graph of the function by using the information that we have. The cubic function will have an vertex of symmetry at (0,-2) and two horizontal tangent lines at (1,-2) and (-1,2) .

Since a < 0, the function is concave down, so the graph will be opened downwards and will have a local minimum at (0,-2) .

It is important to note that this is one possible equation for a cubic function that has horizontal tangent lines at (1, −2) and (−1, 2), but there may be other possibilities.

Jane typed all the natural numbers between m and k (where k>m), which implies she wrote all the positive integers between m and k, inclusive. Jane would have written the numbers 5, 6, 7, 8, 9, and 10 if m was 5 and k was 10.

What are natural numbers?

Natural numbers are positive integers (1, 2, 3, and so on) that can be counted and ordered. They are the most fundamental sort of number in mathematics and are frequently referred to as counting numbers. Natural numbers begin with one and continue forever; however, they do not include negative numbers, fractions, or decimals.

Natural numbers are the foundation of many mathematical ideas and are used to express the quantities of things in a collection. Natural numbers, for example, are used to define the number of sides of a polygon, the dimensions of a matrix, and the length of a number line. They are also used to indicate how much time has elapsed.

Simon Effect
1) How would you design a task demonstrating the auditory version of the Simon effect?

Answers

The answers include the following below:

If the signal is present the person can decide that it is present or absent and the outcomes are called hits and misses.If the signal is absent the person can still decide that the signal is either present or absent which are called false alarms or correct rejections respectively therefore false alarms = correct rejection. A task demonstrating the auditory version of the Simon effect will be putting the hands close to or far from the loudspeakers.

What is Simon effect?

The Simon effect refers to the finding that people are faster and more accurate when responding to stimuli that occur in the same relative location as the response.

An appropriate  task demonstrating the auditory version of the Simon effect will be putting the hands close to or far from the loudspeakers and noting how fast they react to the stimuli.

Choose the correct type of observational study below. â“”A. prospective B. retrospective O C. cross-sectional

Answers

The type of observational study in the following scenario is considered as prospective study.

A prospective study, also known as a prospective cohort study, is a type of longitudinal study in which researchers follow and watch a group of individuals across time to collect data and track the development of outcomes. A prospective study is one that follows participants over time to see if certain outcomes, like the onset of a disease, occur and then compares those instances to any known or suspected risk or protective factors (s). It is common practice to follow a group of people, or a "cohort," for an extended period of time as part of the study. In this scenario, the researcher wants to learn how closeness to a traumatic event might effect healing time by conducting interviews with victims and witnesses over the next 10 years. Hence, it fits the criteria for a prospective observational study.

find the charge q(t) that crosses the dashed line going from left to right in the time interval (0, t) [s].

Answers

The charge q(t) that crosses the dashed line going from left to right in the time interval (0, t) [s] is given by q(t) = q0 + (t)I,

The charge q(t) that crosses the dashed line going from left to right in the time interval (0, t) [s] is calculated by the formula q(t) = q0 + (t)I, where q0 is the initial charge and I is the current.

The charge q(t) that crosses the dashed line going from left to right in the time interval (0, t) [s] is given by q(t) = q0 + (t)I, where q0 is the initial charge and I is the current. To calculate q(t), we need to first calculate the initial charge q0 and then calculate the current I. To calculate q0, we need to integrate the current I over the time interval (0, t). To calculate q(t), we need to know q0 and I. Then, we can calculate q(t) by multiplying t by I and adding it to q0. For example, if q0 = 3 C and I = 2 A, then q(t) = 3 + (t)(2) = 3 + 2t C.

What are arithmetic operations?

Arithmetic operations is a branch of mathematics, that involves the study of numbers, operation of numbers that are useful in all the other branches of mathematics. It basically comprises operations such as Addition, Subtraction, Multiplication and Division.

These basic mathematical operations (+, -, ×, and ÷) we use in our everyday life. Whether we need to calculate the annual budget or distribute something equally to a number of people, for every such aspect of our life, we use arithmetic operations.

The four basic arithmetic operations in Maths, for all real numbers, are:

Addition (Finding the Sum; ‘+’)

Subtraction (Finding the difference;  ‘-’)

Multiplication (Finding the product; ‘×’ )

Division (Finding the quotient; ‘÷’)

Answers

The value of x in the given polygon is 31 degrees.

What are exterior angles?

An exterior angle is an angle created by the expansion of the neighboring side and one of the sides of a closed shape construction, such as a polygon. Regardless of the number of sides in the polygons, the sum of the measures of the outside angles is equal to 360 degrees.

The sum of the exterior angle of any polygon is 360 degrees.

So,

360 = 57 + 41 + 82 +x + 62 + 87

360 = x + 329

x = 31

Hence, the value of x in the given polygon is 31.
