Triangle DEF is formed by connecting the midpoints of the side of triangle ABC. The lengths of the sides of triangle ABC are shown. Find the perimeter of triangle DEF. Figures not necessarily drawn to scale.​

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.

The values that make the inequality -w<-8 true are 8.1, 9, 13.

The  equivalent inequality is w > 8.

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.

Now putting w = -13, -8, -3, 07, 8.1, O-9, -7.9, O, 7.9, 9, -8.1, 0 -7, 03, 8, 13 in the given inequality.

-(-13) < -8 → 13 < -8 (false)

-(-8) < -8 → 8< -8 (false)

-(-3) < -8 → 3 < -8 (false)

-7 < -8  (false)

-(8.1) < -8  (true)

-(0-9) < -8 → 9 < -8 (false)

-(-7.9) < -8 → 7.9 < -8 (false)

-9 < -8 (true)

-(0-7) < -8 → 7 < -8 (false)

-(03) < -8 → 3 < -8 (false)

-8 < -8 (false)

-13 < -8 (true)

Rewrite the given inequality:

Multiply -1 on both sides:

(-1) × (-w) > (-1) × (-8)

w > 8

She then turned off (point 2) the water for a while and some of the water drained out of the bathtub. That, the water level dropped from point 2 to point 3

Tia turned the water back on(point 3) at the same rate as before until the bathtub was full (point 4). As you can see there is an increase from point 3 to point 4.

Answer: LINE A (take a look at the slope of the lines they all have the same x axis but the y axis # changes which is what changes our slope) making a the answer

Step-by-step explanation:

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 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 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.
