The slope of the line through − 7 − 2 and − 6 7 is 9. A line's steepness can be determined by looking at its slope.

Where y and x denote the first and second values, respectively, and y and x2 denote the third and fourth values, respectively, and m is the slope

I by itself would result in m in our scenario.

m= y2 - y/x2 - x

Since x and y are random positions, I will state that the first point, X, is at (-7, -2) and the second point, Y, is at (-6, 7). Therefore, we will enter the values below in their place:

m= [7 -(-2)]/ (-6) -( -7)]

m= 9/1

m = 9

The slope of the equation would be nine.

Answer:

6: H

Step-by-step explanation:

6: We only want a pound of fertilizer, if we have 7.8 pounds then we would have to divide by the cost in order to get only the cost of one. 67.86 ÷ 7.8 = 8.70

3: 3/4 is less than one hour. We only want one hour. We divide the 18 miles by 3, which is 6 but since it's a little less than an hour, it must be lower. The only option less than 6 is 4.5

The graph of a function can be sketched by plotting points.

First and foremost, it is to be determined if the function is odd/even or periodic. Next, we find the x and y intercepts. To sketch a graph of a function, one can start by plotting a few points that lie on the graph using the coordinates given by the function. For example, if the function is y = x², then points (0, 0), (1, 1), and (2, 4) can be plotted by substituting the values of x into the function to find the corresponding values of y.

Subsequent to this, one can connect the points with a smooth curve to form the graph of function. If the function is a straight line, the graph will be a straight line. If the function is quadratic, the graph will be a parabola. The graph may take on a more complicated shape for more complex functions.

The machine discharge more than 7.0 oz or does the difference represent chance variation is 0.0274

What is meant by variation?

In math, variance refers any difference between the individuals in a species or groups of organisms of any species.

Here we have given that a coin-operated soft drink machine was designed to discharge, on average, 7 oz of beverage per cup. in a test of the machine, 10 cupful's of beverage were drawn from the machine and measured. the average and SD of the ten measurements were 7.1 oz and 0.12 oz, respectively. assume that the histogram of beverage discharge from this machine roughly follows a normal curve.

And we need to find machine discharge more than 7.0 oz or does the difference represent chance variation.

By using the Applet, to find the exact p-value we first need to find P(Z≥2.63) where Z is a t9​ random variable.

=> P(Z≥2.63)=0.0137

=> 2×P(Z≥2.63)=0.0274

=> P-value=0.0274

So, the p-value associated with the test is 0.0274

∠A = ∠C  by congruent parts of congruent sides

Corresponding parts of congruent triangles is referred to as CPCT. According to the CPCT theorem, if two or more triangles are taken that are congruent to one another, then the corresponding angles and sides of the triangles are likewise congruent to one another.

According to the given Information

Given

AB = CB

DB bisects ∠ABC

∠ABD = ∠CBD

Proof

In Δ ABD and Δ CBD

         AB = CB ( given )

   ∠ABD = ∠CBD  ( given )

What is the order from least to greatest?

There are two ways to arrange a set of integers in mathematics. It implies that there are two possible orderings for the numbers: ascending and descending. Ascending order refers to the arrangement of numbers in which the smallest number comes before the largest. The numbers are listed in this fashion in ascending order. It is ideal for the first number to be less than the second.

Descending order refers to arranging the integers from largest to least value. The numbers are in decreasing order in this manner. It is ideal for the first number to be higher than the second.

Given inequality is -w < -8.

What is inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.

The amount of variability between groups quantified is group of answer choices comparing the standard deviations of each group to each other comparing the sample means of each group to each other.

A variability measure is a summary statistic that describes the amount of variation in a dataset. Central tendency measures describe typical values, while variability measures define how far away data points tend to be from the center. We talk about variability in the context of value distribution. A small variance indicates that the data points tend to be clustered near the center. A large spread means they tend to move further apart.

Analysts often use averages to summarize the center of a population or process. Averages are good, but people are often more sensitive to fluctuations. The less variability in the distribution, the more consistent the values ​​within the dataset. However, the higher the variability, the more diverse the data points and the more likely extreme values ​​will occur. Therefore, understanding variability helps us to understand the likelihood of anomalous events.

Meteorologists have seen weather forecasts showing extreme heat and drought in some areas and flooding in others. We often feel more uncomfortable in the extreme than in the middle. Understanding this variability about the mean provides important information.

The values of a and b are 6.83 and 1.17 respectively rounded to the nearest hundredth.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let the numbers be a and b.

Given, (a + b) = 8..(i) and ab = 8.

Now,

(a + b)² = a² + 2ab + b².

64 = a² + b² + 16.

a² + b² = 48.

Now,

(a - b)² = a² + b² - 2ab.

(a - b)² = 48 - 16.

(a - b)² = 32.

(a - b) = 5.66...(ii)

A system of a linear equation is said tk be consistent if it had at least one solution is true

In a linear equation, the largest power of the variable is always equal to 1. It's also known as a one-degree equation. Typically, Ax + B = 0 is used to represent a linear equation with one variable. The variables x, A, and B in this case serve as constants and coefficients, respectively. The typical form of a linear equation with two variables is Ax + By = C. Here, x and y are the variables, A and B are the coefficients, and C is the constant. If there is at least one solution, a set of linear equations is considered to be consistent. This means that when all equations in the system are solved, at least one set of values for the variables can be found which satisfy all equations simultaneously. So, the statement is true.
