twice a certain number x is less than 8. Find the range of values of the number​

To find the median of a set of numbers, you first need to put the numbers in order from smallest to largest. Once the numbers are ordered, the median is the middle number in the list.

In this case, the ordered list of numbers is: 2, 3, 3, 4, 5, 6, 7.

The median of this list is 4.

Sorting all the data points and selecting the central one are required to determine the middle number (or if there are two middle numbers, taking the mean of those two numbers). Example: The number 4 is in the middle when the numbers are grouped (1, 4, 7), making it the median of the numbers (4, 1 and 7).

By summing up the center values and dividing them by two, you may obtain the mean and, from there, the median.

A factor is a number that completely divides another number.

To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.

The two components that makeup 98 are: (1, 98), (2, 49), and (7, 14). 1, 2, and 7 make up the first three factors of 98.

So, in order to get what we can get into 98, we need to list down the factors of 98.

P/Q is in the lowest form as the when the HCF is 1 and if we divide it by 1 P/Q remains same so it is the lowest form ,if P and Q have no common factor other than 1.

It is possible to express rational numbers in the form p/q, where p and q are integers and q≠0.

If there is just one other common factor between the denominator and numerator of a rational number, that number is said to be in its lowest form. In other words, if the HCF of a and b is 1 and a and b are relatively prime, then we can state that a rational number a/b is considered to be in its simplest form.

as described in the above contion in order to reduce any rational number to its lowest form we need to divide both numerator and denominator by the HCF of p,q . suppose if the HCF of p,q is 1 then divide p and q 1 won't change the value of the rational number.

so, now it is shown that the given rational number can't be further deduced and hence we conclude that a rational number is in lowest form when HCF of its numerator and denominatior is equal to 1.

The arithmetic mean, also known as the average, of a set of numbers is found by adding up all the numbers in the set and dividing by the total number of numbers in the set. In this case, the set of numbers is 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20. When we add up all the numbers in the set, we get a total of 155. There are 10 numbers in the set, so the average is 155 / 10 = 15.5.

To find the arithmetic mean, we first need to add up all the numbers in the set. Then, we divide that sum by the total number of numbers in the set. This gives us the average value of the set.

the equation in slope-intercept form that represents the total number of riders over time is: Y = 33x + 132

To find the equation in slope-intercept form that represents the total number of riders over time, we need to find the slope and the y-intercept of the line. The slope of a line is the change in y divided by the change in x, or the rise over the run. In this case, the change in y between the first and second times is 165 - 132 = 33, and the change in x is 1 - 0 = 1. So the slope of the line is 33/1 = 33. The y-intercept is the point at which the line crosses the y-axis, or the value of y when x is 0. In this case, the y-intercept is 132, since that is the total number of riders at the beginning of Tara's shift when x is 0.

Therefore, the equation in slope-intercept form that represents the total number of riders over time is:

Y = 33x + 132

Note that the slope (33) is the coefficient of the x term, and the y-intercept (132) is the constant term.

The mean of the given data set is 26.

One of the most significant and often employed metrics of central tendency is the mean. In mathematics, there are various different kinds of means. In statistics, the mean is the product of all the values in a set of data divided by the total number of values in the data for a particular set of observations.

To put it another way, calculating the mean of a data set only requires adding up all the values and dividing the result by the total number of values.

The mean formula in statistics for a set is defined as the sum of the observations divided by the total number of observations.

Mean = 25+30+27+23+25/5

Mean = 130/5 = 26

Thus, the mean of the given data set is 26.

  (c)  two right triangles, each with both legs 40 inches long

Step-by-step explanation:

You want to know which pair of triangles are congruent, given their descriptions.

There are basically 4 theorems that allow you to claim congruence of triangles:

  AAS, ASA, SAS, SSS

A fifth one applies to right triangles only: HL.

These tell you that you need to have three matching parts: 3 sides, 2 sides and the angle between (except right triangle), or 1 side and 2 angles.

An isosceles triangle with only one or two sides defined is not sufficient.

A right triangle with only the hypotenuse defined is not sufficient.

A right triangle with two legs and the (right) angle between them has a sufficient number of matching parts to be able to claim congruence to another triangle similarly defined.

The answer to the above question will be as follows:

We solve the question in the following way,

Given inequality is y≥7x- 4

Let us first consider the linear equality of the equation as

y= 7x- 4

When we consider this with the general slope form of a straight line given by: y=mx+c, we get

m=7 and c= -4

Now, we know that for the ‘greater than or smaller than equal to’ sign, the graph is mapped using a solid line and is shaded away from the origin of the graph (0,0).

Thus for this graph, we will use a solid line to represent the line y=7x- 4 and shade the graph above the line. Therefore option (c.) is correct.

The sample of 200 students surveyed by the statistics students was composed of 50 first-year students, 50 sophomores, 50 juniors, and 50 seniors. This could be represented by the following formula:

Sample Size = 50 First-Years + 50 Sophomores + 50 Juniors + 50 Seniors

In order to break down this sample size into a mathematical formula, the students can use the following equation:

Where n1, n2, n3, and n4 represent the number of first-year, sophomore, junior, and senior students surveyed, respectively.

Therefore, using the original sample size, the equation would be:

The parallel equation of y = 3x + 1 is y = 3x

The slope is computed mathematically as "rise over run" (change in y divided by change in x).

In accordance with the slope equation, the slope of such a line may be determined by dividing the rise of the line between two positions by the run of the same line between the same two sites.

That is to say,

Given equation: y = 3x + 1

A point from which the parallel line will pass through is (0,0)

To find the slope using the slope-intercept form:

The slope-intercept form is: y = mx + b

Where, m = slope

b = y - intercept

Now comparing this equation with given equation, we find, slope (m) = 3

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope 3 and a given point (0,0) to substitute for x₁ and y₁ in the point slope form: y - y₁ = m (x - x₁), which is derived from the slope-equation,

m = (y₂ - y₁)/ (x₂ - x₁)

so, putting the value we get,

y - 0 = 3 ( x - 0 )
