Units are a natural number, a natural number that are negative, or zero. The number zero and any number generated by adding one to it repeatedly. A single integer or the product of two integers (division by zero excluded).

What exactly are integers?

In mathematics, integers are the collection of positive and negative numbers. Integers, like whole numbers, do not include the fractional element. Thus, integers are numbers that can be positive, negative, or zero, but not fractions. On integers, we can do all arithmetic operations such as addition, subtraction, multiplication, and division. Integers include numbers such as 1, 2, 5, 8, -9, -12, and so on. "Z" is the symbol for integers.

The number zero and any number generated by adding one to it repeatedly. A single integer or the product of two integers (division by zero excluded).A natural number, a negative of a natural number, or zero is a unit of an abstract mathematical system according to the principles of arithmetic. 

e.g. 1,2,0, 0+1, 0+2+3, 8, 8/2=4, -8/2=-4 etc. all are units of  an abstract mathematical system subject to the laws of arithmetic.

Answer:

[tex] \frac{14}{16} \: and \: \frac{13}{16} [/tex]

Step-by-step explanation:

So we have these two fractions

[tex] \frac{7}{8} \: and \: \frac{13}{16} [/tex]

Does 8 go into 16? Yes. It goes in twice because 8 times 2 is 16. That means 16 is our common denominator.

Because of that, since we multiplied 8 by 2, we will do the same to the 7. 7 times 2 is 14.

Because of that we have 14/16 and 13/16 as our answers.

Answer:

Time (min) Distance (km)

6       9

12      18

24     36

15     45

Step-by-step explanation:

The table shows equivalent ratios between time in minutes and distance in kilometers. An equivalent ratio means that the ratio of time to distance stays the same, even though the numbers themselves change.

For example, in the first row, the ratio of time to distance is 6 minutes to 9 kilometers. In the second row, the ratio of time to distance is 12 minutes to 18 kilometers. Despite the change in numbers, the ratio of time to distance remains the same. This is why these ratios are considered equivalent.

Answer:

27.87

Step-by-step explanation:

In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the sum of the squares of the two shorter sides is equal to the square of the length of the hypotenuse.

Using the given sides, we can write the equation:

AB^2 + BC^2 = AC^2

Substituting the given values, we have:

17^2 + 22^2 = AC^2

Simplifying the left side, we get:

289 + 484 = AC^2

773 = AC^2

Taking the square root of both sides, we find:

AC = √773 = 27.87

Rounding to two decimal places, the length of side AC is approximately 27.87.

The mean is sensitive to outliers and will not accurately represent the center of the data if the distribution is significantly skewed.

The mean is a measure of central tendency that is calculated by adding up all values in a dataset and dividing by the number of values. It is often used as a measure of average since it takes into account all values in the dataset. However, it is an inappropriate measure of central tendency when the data distribution is severely skewed. A skewed distribution is one in which the data is not distributed evenly around the mean, and the data is either concentrated in the lower or higher end of the range. Since the mean is sensitive to outliers, it will be greatly affected by these values and not accurately represent the center of the data. In this case, it is more appropriate to use the median as a measure of central tendency since it is not affected by outliers. The median is the middle value of a dataset when the data is sorted from smallest to largest and is a better representation of the true center of the data in a skewed distribution.

The probability of buying 3 tires is 0.05 and the cumulative probability distribution table is created.

What is meant by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given,

     Percentage of people who buys 4 tires = 50%

      Percentage of people who buys 2 tires = 32%

      Percentage of people who buys less than 2 tires = 13%

    Percentage of people who buys none = 6%

a) Prob(X=0) = 0.06

    Prob(X=2)  = 0.32

   Prob(X=4)  = 0.50

 Prob(X < 2) = Prob(X=0) + prob(X=1) = 0.06+ prob(X=1)

   prob(X=1) =   Prob(X < 2) - 0.06  = 0.13 - 0.06 = 0.07

Therefore prob(X = 3) = 1 - ( 0.5+0.32+0.07+0.06) = 1 - 0.95 = 0.05 = 5%

b) Cumulative probability distribution is as given in the figure.

The slope of the least-squares regression line is not directly related to the fraction of the variation in the response variable that is explained by the explanatory variable.

The slope of the least-squares regression line is a numerical measure of the rate of change in the response variable for a unit change in the explanatory variable. It does not directly relate to the fraction of the variation in the response variable that is explained by the explanatory variable. This is because the fraction of the variation in the response variable that is explained is determined by the correlation coefficient, which is a measure of how well the regression line fits the data. The slope of the least-squares regression line is unitless, meaning it does not have any specific unit such as meters, seconds, or degrees. The slope of the least-squares regression line is simply a numerical measure of the rate of change in the response variable per unit change in the explanatory variable. This is different from the fraction of the variation in the response variable explained by the explanatory variable, which is determined by the correlation coefficient.

The coordinates after the rotation of 90° will be (-2, -3), (3, 4), and (4, -5) respectively.

Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.

Precession, nutation, and intrinsic rotation are the names of these rotations.

Shapes can be rotated by being moved around a fixed point (clockwise or anticlockwise, and by a certain number of degrees).

Although the shape will remain precisely the same, its location within the room will shift.

So, we have:

(-3,2),(4,-3) and (-5,-4)

Now, the graph then as follows.

Now, rotate them to 90°.

(Refer to the graph attached below)

Then, the coordinates after 90° rotation will be:

(-3,2) = (-2, -3)

(4,-3) = (3, 4)

(-5,-4) = (4, -5)

Therefore, the coordinates after the rotation of 90° will be (-2, -3), (3, 4), and (4, -5) respectively.

Answer:

Step-by-step explanation:

If you work 55 hours in one week and earn $15 per hour, your gross pay before taking into account any overtime can be calculated as follows:

Gross pay = 55 hours x $15/hour = $825

If you work overtime, which is time and a half, the additional pay can be calculated as follows:

Overtime pay = ($15/hour x 1.5) x (55 hours - 40 hours) = ($22.50/hour x 15 hours) = $337.50

So, the total gross pay including the overtime pay is:

Gross pay = $825 + $337.50 = $1,162.50

Therefore, the total gross pay for working 55 hours in one week at $15 per hour, with overtime pay calculated as time and a half, is $1,162.50.

Now in the given question,

Here we have a graph of inequalities, and we just need to see if the pair (75, 100) is a solution.

The solutions of the system are all the points in the intersection of the two shaded areas (in this case are all the points in the green area)

Now, clearly the point (75, 100) is not a solution

The first step is to rewrite the equations in standard form by subtracting the constant from each side.

Standard form is a type of numerical notation used to express large numbers in a concise form. It is based on powers of 10, which means each place value of a number is multiplied by a power of 10. Standard form is typically used in scientific and mathematical applications, and it is also known as scientific notation. To write a number in standard form, the number is written as a coefficient, followed by the base of 10, raised to an exponent.

3x - 2y = 10  becomes  3x - 2y - 10 = 0

3x - y = 17 becomes 3x - y - 17 = 0

Let's multiply the first equation by 2 and the second equation by 3.

2(3x - 2y - 10) = 0

3(3x - y - 17) = 0

6x - 4y - 20 = 0

9x - 3y - 51 = 0

The next step is to add the two equations together.

6x - 4y - 20 + 9x - 3y - 51 = 0

15x - 7y - 71 = 0

The last step is to solve for the variable.

15x - 7y = 71

The equation that determines the intersection of line with a clipping triangle is ax + by + c = 0 [1]. The solution has been obtained by using functions.

What is a function?

A function is described as a relationship between a group of inputs with one output each. A function is, to put it simply, a relationship between inputs in which each input is connected to exactly one output. Every function has a domain and a codomain, or range. A function is typically represented by the notation f(x), where x represents the input. A function is typically shown as y = f(x).

The equation ax + by + c = 0 [1] represents the line in question. A list of pairs of coordinates for each intersection point and the number of intersections (count) should be returned by the function (list).

A list of items can be sent to the function count list, which will return the total number of objects in the list. The function returns the number of objects in the specified list after accepting an array or list of objects.

Hence, the equation that determines the intersection of line with a clipping triangle is ax + by + c = 0 [1].
