Answer:(192/9.6)÷7=20/7

Step-by-step explanation:

Answer:

A() it is located _25 and is the right of point A on the number line

Answer:

The Answer is C

Step-by-step explanation:

so if u draw out a number line, point A will be on the left side of the number line or in this case "0". So it is saying "point b is 5 less than point A" so since Point A is "-20" and it says "5 less than point A" so it would be adding up 5 more to -20 so it would be -25. But if it was 5 more than point A it would have been -15. If u take an example of money, like if u owe someone $20, it would be -$20 in your balance, and if he or she says u need to owe me 5 more $'s cuz there was damage now in your balance it would be -25.

The percentage profit for the shop owner is 197.6%.

Percentage profit is the ratio of the profit on a good or item and the the cost price expressed as a percentage.

The cost price of the book in US dollars will be: 10 * 1/0.85 = 11.76 USD

Selling price in USD = 35 USD

Profit = 35 - 11.76

Profit = 23.24 USD

Percentage profit = 23.24/11.76 * 100%

Percentage profit = 197.6%

In conclusion, the percentage profit is the profit expressed as a percentage of the cost price.

the width of the river is approximately 64.03 feet.

To determine the width of the river, we can use the concept of triangle similarity.

Let's assume that the river width is represented by the variable "x".

From the information given, we have a right triangle formed by the river, the fishing hole, and the campsite. The campsite is located 200 feet from the fishing hole, and the river width is the unknown side.

Using the Pythagorean theorem, we can set up the equation:

x^2 + 200^2 = (200 + 110)^2

Simplifying the equation:

x^2 + 40000 = 44100

x^2 = 44100 - 40000

x^2 = 4100

Taking the square root of both sides:

x = sqrt(4100)

x ≈ 64.03 feet

Therefore, the width of the river is approximately 64.03 feet.

The size of the photograph has increased by 200% after being enlarged to three times its previous size.

To find the percentage increase in size, we compare the new size of the photograph to its original size. If the photograph has been enlarged to three times its previous size, it means the new size is three times the original size.

Let's assume the original size of the photograph is x. After enlargement, the new size becomes 3x. To calculate the percentage increase, we need to find the difference between the new size and the original size, which is 3x - x = 2x.

The percentage increase is given by the formula: (increase/original size) * 100. In this case, the increase is 2x, and the original size is x. Plugging in these values, we get (2x/x) * 100 = 200%.

Therefore, the size of the photograph has increased by 200%. This means the new size is 200% larger than the original size, or the size has doubled.

To find the value of the function f(x) = \(2x^3 - 5x + 7\) at x = -4, we substitute -4 into the function and simplify. The value of the function at

x = -4 is -101.

To calculate the value of the function \(f(x) = 2x^3 - 5x + 7\)at x = -4, we substitute -4 for x in the equation:

\(f(-4) = 2(-4)^3 - 5(-4) + 7\)

Simplifying the expression, we have:

f(-4) = 2(-64) + 20 + 7

f(-4) = -128 + 20 + 7

f(-4) = -101

Therefore, when x = -4, the value of the function \(f(x) = 2x^3 - 5x + 7\)is -101. This means that if we substitute -4 into the function, we get a result of -101.

The surface area of the rectangular prism is 310 square feet

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

5 ft

15 ft

4 ft

Rewrite the parameters properly

So, we have

Length = 5 ft

Width = 15 ft

Height = 4 ft

The surface area of the rectangular prism is then calculated as

Surface area = 2 * (Length x Width + Width x Height + Height x Length)

Substitute the known values in the above equation

So, we have the following equation

Surface area = 2 * (5 * 15 + 5 * 4 + 4 * 15)

We can compute various descriptive statistics such as the mean, median, mode, range, variance, standard deviation, sum of values, and sum of squared deviations.

The sample mean, also known as the average, provides information about the central tendency of the variable X. It represents the typical or average number of coupons used by the shoppers in the sample. In this case, calculating the mean of the given data would provide an estimate of the average number of coupons used over the 6-month period.

The sample standard deviation measures the dispersion or variability of the data points around the mean. It indicates how much the individual observations deviate from the mean value. A higher standard deviation implies greater variability, indicating a wider range of coupon usage among the shoppers in the sample.

By computing the sample mean and standard deviation, we can understand the average coupon usage and the degree of variability in the data. These statistics help us summarize and interpret the characteristics of the variable X, allowing us to make comparisons, identify outliers, assess the spread of the data, and make inferences about the larger population from which the sample was drawn.

Answer:

I believe its 4

Step-by-step explanation:

The price vectors a. p₁ = 3 and p₂ = 2, Mary will consume only good 1.

Here we have the Utility function as

U(x₁ , x₂) = 3x₁ + x₂

From the given utility function we can clearly see that these goods are substitutes for each other

Now,

δU/δx₁ = 3

δU/δx₂ = 1

Hence we get the Marginal Rate of Substitution or MRS

\(=- \frac{\delta U/ \delta x_1 }{\delta U/ \delta x_2}\)

= -3

The MRS signifies that for every additional unit of 1, Mary is willing to give up 3 units of good 2

|MRS| = 3

For Mary to only consume good 1, |MRS| > p₁/p₂

Hence here we get the p/p ratio for the 4 price vectors to be

a. 3/2 = 1.5

b. 10/3 = 3.33

c. 4

d. 15.4 = 3.75

Hence we can clearly say that for the price vectors p₁ = 3 and p₂ = 2, Mary will consume only good 1.

The sum of three consecutive even numbers is 186. The three even numbers are 62, 64, and 66.

To arrive at this solution, use the formula (n + (n + 2) + (n + 4)) = 186, where n is the first even number. Solving for n gives us 62. Thus, the three consecutive even numbers are 62, 64, and 66.
To arrive at this answer algebraically, we can start by finding the average of the three numbers.

The average of three numbers is equal to the sum of those numbers divided by 3. Thus, the average is equal to 186 divided by 3, which equals 62.

Since the three numbers are consecutive, the second number is two more than the first, and the third number is two more than the second. Thus, the numbers are 62, 64, and 66.

Options a, b, d, and g are the correct conditions for a Binomial Distribution.

The four conditions necessary for X to have a Binomial Distribution are:

a. There are n set trials: In a binomial distribution, the number of trials, denoted as "n," must be predetermined and fixed. Each trial is independent and represents a discrete event.

b. The trials must be independent: The outcomes of each trial must be independent of each other. This means that the outcome of one trial does not influence or affect the outcome of any other trial. The independence assumption ensures that the probability of success remains constant across all trials.

d. There can only be two outcomes, a success and a failure: In a binomial distribution, each trial can have only two possible outcomes. These outcomes are typically labeled as "success" and "failure," although they can represent any two mutually exclusive events. The probability of success is denoted as "p," and the probability of failure is denoted as "q," where q = 1 - p.

g. The probability of success, p, is constant from trial to trial: In a binomial distribution, the probability of success (p) remains constant throughout all trials. This means that the likelihood of the desired outcome occurring remains the same for each trial. The constant probability ensures consistency in the distribution.

The remaining options, c, e, and f, are not conditions necessary for a binomial distribution. Option c, "Continue sampling until you get a success," suggests a different type of distribution where the number of trials is not predetermined. Options e and f, "You must have at least 10 successes and 10 failures" and "The population must be at least 10x larger than the sample," are not specific conditions for a binomial distribution. The number of successes or failures and the size of the population relative to the sample size are not inherent requirements for a binomial distribution.

This dilemma arises because oscillation requires two degrees of freedom while a equation one-dimensional system can never have more than one. An example of a constrained system is a basic harmonic oscillator.

This paradox results from the fact that oscillation needs two degrees of freedom whereas a one-dimensional system only has one. Position is the only variable in a one-dimensional system, hence oscillation is not feasible. But one example of a restricted system, where a constraint provides an additional degree of freedom, is a straightforward harmonic oscillator. The constraint in this scenario is a spring's force, which acts as a restoring force whenever the system deviates from its equilibrium state. The system can oscillate and move back and forth along the x-axis thanks to this restoring force. Thus, although having only one degree of freedom, the basic harmonic oscillator is an example of a one-dimensional system that can oscillate.

To solve the inequalities -2x + 4 < 8 and 3x + 4 ≤ -5, we will solve them individually and then represent the solutions on a number line.

For the first inequality, -2x + 4 < 8, we will isolate x:

-2x + 4 - 4 < 8 - 4

-2x < 4

Dividing both sides by -2 (remembering to reverse the inequality when multiplying/dividing by a negative number):

x > -2

For the second inequality, 3x + 4 ≤ -5, we isolate x:

3x + 4 - 4 ≤ -5 - 4

3x ≤ -9

Dividing both sides by 3:

x ≤ -3

Now we represent the solutions on a number line. We mark -2 with an open circle (since x > -2), and -3 with a closed circle (since x can be equal to -3). Then we shade the region to the right of -2 and include -3 to represent the solutions.

Even though dividing a fraction by a whole number might be challenging, it is simple to achieve with a few steps. By placing the full number above 1, you must first divide it into a fraction. After that, multiply the fraction you are dividing by the inverted version of the fraction. Lastly, simplify the response as much as possible.

For instance, to multiply 3/4 by 2:

Put 2 over 1, making it 2/1, to make it a fraction.

To get 1/2, invert 2/1.

To get 3/8, multiply 3/4 by 1/2.

Divide the numerator and denominator by 3 to get 1/4, which is the simplest representation of the fraction 3/8.

By Probability, the number of books that are either science or fiction is 1018.

A set that contains every element in at least one of the two sets is called the union of two sets.

A new set that includes every element from both sets is created when two sets intersect.

The formula including Union and Intersection is :

n(A ∪ B) = n(A) + n(B) – n(A ∩ B)

Let A= Science Books

B = Books of function

A ∪ B = Science Fiction Books

A ∩ B = Either science or fiction Books

n(A)= 463

n(B) = 592

n(A ∩ B) = 37

Therefore, n(A ∪ B) is calculated below:

n(A ∪ B) = 463 + 592 - 37

n(A ∪ B) = 1055 - 37

n(A ∪ B) = 1018

Therefore, the number of books that are either science or fiction is 1018.
