Which of the following is a system of linear inequalities in two variables?​

The length of each of piece of board is 40 cm or 0.4 m.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Gillian has a board that is 2 meters long.

She cuts the board into 5 equal pieces.

Now, the length of each piece is

= 200 cm /5

= 40 cm

Hence, the length is 40cm or 0.4 m.

The equation that can be used to find d is 0.25d - 3.50 = $55.

The first step is to determine the total cost when the distance travelled is d.

Total cost when the first rental company drives d miles = $55

Total cost when the second rental company drives d miles = cost per day + [cost per mile x (d - 150)

= $34 + [$0.25 x (d - 150)]

$34 + 0.25d - 37.50

0.25d - 3.50

The point Q = (-12, 1, 24) is a point at which the vector field F and the line l are perpendicular, and the equation for the set of all points at which f and l are perpendicular is 6x₁ + 3y₁ + 4z₁ = 0.

To find a point at which the vector field F and the line l are perpendicular, we need to find the point at which the dot product of the vector F and the direction vector of the line l is zero.

The direction vector of the line l is given by:

d = (1, 1, 4)

The vector F at the point (x₁, y₁, z₁) is given by:

F(x₁, y₁, z₁) = x₁ i + (x₁ + y₁) j + (x₁ - y₁ + z₁) k

The dot product of F and d is:

F(x₁, y₁, z₁) ⋅ d = x₁ + (x₁ + y₁) + 4(x₁ - y₁ + z₁)

Setting this equal to zero, we have:

x₁ + (x₁ + y₁) + 4(x₁ - y₁ + z₁) = 0

Expanding, we get:

6x₁ + 3y₁ + 4z₁ = 0

We can substitute x₁ = 3 - 5t, y₁ = t - 4, and z₁ = 4 + 4t into this equation to find t:

6(3 - 5t) + 3(t - 4) + 4(4 + 4t) = 0

Expanding, we get:

72 - 30t + 3t - 12 + 16 + 16t = 0

Simplifying, we get:

100 = 20t

So, t = 5.

Substituting t = 5 back into x₁ = 3 - 5t, y₁ = t - 4, and z₁ = 4 + 4t, we get:

x₁ = 3 - 5 * 5 = -12

y₁ = 5 - 4 = 1

z₁ = 4 + 4 * 5 = 24

The point Q = (-12, 1, 24) is a point at which the vector field F and the line l are perpendicular.

The set of all points at which F and l are perpendicular is given by the equation:

6x₁ + 3y₁ + 4z₁ = 0

This represents a plane in 3-dimensional space, perpendicular to the vector F at all points.

The sequence diverges.

There is just one possible outcome for a sequence: either it converges or it diverges. This does not imply that we can always detect whether the sequence converges or diverges; in fact, there are occasions when it can be very challenging for us to do so.

The limit of the sequence an = cos(2n) / 5n as n approaches infinity does not exist, so the sequence diverges.

The cosine function oscillates between -1 and 1, so the value of cos(2n) can be arbitrarily large or small as n gets larger. As a result, the ratio of cos(2n) to 5n also becomes arbitrarily large or small, and the limit does not exist.

The top interval in a frequency table for a set of scores ranging from a high of X = 75 to a low of X = 23 would be 73-75.

This is because the bottom interval is 18-23, and the intervals in a frequency table are generally of equal size. This means that the highest interval must be of a similar size, and would thus be 73-75. The purpose of a frequency table is to show how often values from a numerical data set occur.

The data is usually divided into intervals of equal size, such as the 18-23 interval mentioned in this scenario. The intervals are usually calculated by subtracting the lowest value from the highest value, and then dividing the result by the number of intervals desired. In this case, the highest interval must be of equal size to the 18-23 interval, resulting in a range of 73-75.

Answer:C

Step-by-step explanation:

Answer:

B. 4w + 10 = 46

Step-by-step explanation:

If we let l be the length of the rectangle and w its width

Fact 1: A rectangle's length is 5 centimeters greater than its width
This translates to l = w + 5 (1)

Fact 2: he perimeter of the rectangle is 46 centimeters
Perimeter is given by 2(l + w)
So fact 2 translates to:
2(l + w) = 45
2l + 2w = 46  (2)

Substitute l = w + 5 from (1) for l in (2):

2(w + 5) + 2w = 46
2w + 10 + 2w = 46

4w + 10 = 46

This is Option B

Answer:

C. 2w + 5 = 46

Reason why is because a rectangle has 4 sides, but you only want to multiply length times the width, to get the perimeter, which is why 2w in the equation is correct.

It also says 5 centimeters greater, the is why it would be + 5 instead of 10.

Response variable defined with:

B. The number or quality of the variable for whom the value the experimenter wants to figure out how the explanatory variable affects.

Option B describes the response variable as the variable of interest that the experimenter is trying to study and understand how it is affected by other variables, known as explanatory variables. The response variable is often the dependent variable in a study and the focus of the analysis.

On the other hand, option A describes a situation in which the effect of two factors on the response variable cannot be distinguished, which is not a definition of the response variable itself. Option C describes a placebo, which is a different concept in experimental design.

Option D is similar to option B but does not describe the response variable as being the focus of the experimenter's study.

The response variable, also known as the dependent variable, is a variable in a statistical model or experiment that is being measured or studied. It is the outcome of interest that the experimenter wants to understand and explain by considering the effects of one or more independent variables, also known as explanatory variables.

The goal of the experiment is to determine how changes in the explanatory variables affect the response variable. In a sense, the response variable is the dependent variable because its value depends on the values of the independent variables.

Understanding the relationship between the response and explanatory variables is important in fields such as science, medicine, and engineering, where researchers are often interested in predicting or controlling outcomes based on various inputs.

Answer:

16.7 years (not sure)

Step-by-step explanation:

To solve this problem, we can use the formula for exponential decay:

y = y0 * (1 - r)^t

Where y is the number of cars after t years, y0 is the initial number of cars (54 million), r is the annual decrease rate as a decimal (6.8% = 0.068), and t is the number of years.

We want to find t when y = 46 million:

46 million = 54 million * (1 - 0.068)^t

Dividing both sides by 54 million:

46 million / 54 million = (1 - 0.068)^t

Taking the natural logarithm of both sides:

ln(46 million / 54 million) = ln((1 - 0.068)^t)

Using the logarithmic identity:

ln(46 million / 54 million) = t * ln(1 - 0.068)

Dividing both sides by ln(1 - 0.068):

t = ln(46 million / 54 million) / ln(1 - 0.068)

Using a calculator, t = approximately 16.7 years. Rounding to the nearest year, it will take 17 years for this country to have 46 million cars.

By organizing the data into intervals and counting the frequency of observations, we can identify the range of values in which the most data points are located.

In statistics, an interval is a range of values within which we expect to find a certain amount of observations.

The number of observations within an interval is known as the frequency, and it can be used to determine where the majority of values lie in a data set.

When we are looking for the interval with the largest number of observations, we are trying to find the range of values in which the most data points are located.

In order to do this, we need to first organize the data into intervals, often called bins, and then count the frequency of observations within each bin.

For example, if we have a data set of 100 heights of people, we could create 10 bins with a range of 10 cm each. The first bin would cover the range of heights from 0-10 cm, the second bin from 10-20 cm, and so on. After counting the number of people in each bin, we can easily see which bin has the largest frequency, and therefore the interval with the largest number of observations.
