What is the quadratic equation in standard form of a 2 b =- 3 and C =- 6?

The presence of a statistically significant difference tells you that there is a large effect size is false.

Statistical significance: When conducting a statistical analysis, researchers aim to determine if the results they observe are statistically significant. Statistical significance is a measure that helps determine whether the observed difference between groups (or the relationship between variables) is unlikely to have occurred due to random chance. It is typically assessed using statistical tests such as t-tests, chi-square tests, or analysis of variance (ANOVA).

Effect size: Effect size, on the other hand, provides a measure of the magnitude or strength of the relationship or difference being studied. It quantifies the practical significance or importance of the effect observed in the data. Effect size is independent of sample size and helps researchers understand the extent to which the independent variable (or intervention) influences the dependent variable.

The misconception in the statement you mentioned is that a statistically significant difference does not necessarily imply a large effect size. Statistical significance focuses on the likelihood that the observed difference is due to more than just chance, while effect size focuses on the magnitude or practical importance of that difference.

In some cases, a study may find a statistically significant difference with a small effect size, indicating that although the groups being compared are different, the practical significance of that difference may be minimal. Conversely, a study may find a statistically nonsignificant difference with a large effect size, suggesting that although the difference observed may not be statistically significant, it still has practical importance.

To gain a comprehensive understanding of the results, it is important to consider both statistical significance and effect size together. This helps researchers interpret the practical implications of their findings accurately.

Therefore, The presence of a statistically significant difference tells you that there is a large effect size is false.

Answer:

390 degrees

Step-by-step explanation:

30 + 360 = 390

The solution of m for question 6 and the value of z for question 10 does not exist.

According to the question,

We have the following information,

6) 1/3 + 2m/3 = 2m/3-2/3

Now, moving the terms with the same variables in one side:

2m/3-2m/3+1/3 = -2/3

Now, when 2m/3 is subtracted from 2m/3 then we have no variable left.

So, the solution of this equation does not exist.

10) 2.5(2z+5) = 5(z+2.5)

Now, multiplying the numbers outside the bracket into bracket:

5z+12.5 = 5z+12.5

Moving the terms with the same variables on one side:

5z-5z+12.5 = 12.5

Now, when 5z is subtracted from5z then we have no variable left.

So, the solution of this equation does not exist.

Hence, the solutions of the equation 6 and equation 10 does not exist.

350 sq ft = 18.75 dollars

1 sq ft = (18.75/350) dollars  .... divide both sides by 350

1 sq ft = 0.053571 dollars approximately

One square foot costs about 0.053571 dollars

Multiply both sides by 2345 to get

Answer:

s = 23 - e

Step-by-step explanation:

In this expression, s is equal to the amount of extra credit Sofia earns. She earns e less points than the 23 points Zeke earns.

So, s (Sofia's points) = 23 (Zeke's points) - e (the difference in points).

The expression is s = 23 - e.

Answer:

∠ABD ≅ ∠CBE

Step-by-step explanation:

So we know that ∠ABC ≅ ∠DBE. Those angles equal the same thing. Let's represent that with x.

So does ABD = CBE?

Well we can model that with our xs.

ABD = ABC + CBD

so ABD = x + CBD

CBE = DBE + CBD

so CBE = x + CBD

Look at what we have!

x + CBD = x + CBD.

You can tell that ∠ABD ≅ ∠CBE because those given angles are equal to each other.

Or for an easier (but lazier) method, you can just look at the diagram, which is actually drawn to a reasonable scale. You can tell right off the bat that none of the other options work.

The true statements are, Line A B and Line C G are parallel, Line C G and Line R S are perpendicular, Line A B and Line R S must intersect and Line segment C G lies in plane X.

Given that Planes X and Y intersect at a right angle. Line AB and CG are on plane X, while line RS is on plane Y. Therefore, line CG lies on plane X.

Since both line AB and CG lie on the same plane, they are parallel to each other.

Since plane X and plane Y are perpendicular to each other and line CG is on plane X while line RS is on plane Y, this means that Line CG and Line RS are perpendicular to each other.

Line AB and Line RS may or may not intersect. They could be skew lines, which do not intersect and are not parallel.

Line segment CG lies on plane X since it is contained within the plane that contains points C, G, and either A or B.

In general form, the equation is 8x² + 30x - 2x = 0.

In factored form, the equation is 4x(2x + 7) = 0.

To solve the equation 8x² + 30x = 2x, we can rearrange it to bring all the terms to one side:

8x² + 30x - 2x = 0

Combining like terms:

8x² + 28x = 0

Now, let's factor out the common factor of 4x:

4x(2x + 7) = 0

To find the solution set, we set each factor equal to zero and solve for x:

4x = 0 -> x = 0

2x + 7 = 0

2x = -7

x = -7/2

Therefore, the solution set for the equation is {0, -7/2}.

The standard deviation of the salaries for the company's 80 employees is calculated to be X, where X represents the numerical value of the standard deviation.

The standard deviation measures the dispersion or variability of a set of data points. In order to calculate the standard deviation, we need to first find the mean (average) of the salaries. Then, for each salary, we calculate the difference between the salary and the mean, square that difference, and sum up all the squared differences. Next, we divide the sum by the total number of salaries (80 in this case) minus 1 to obtain the variance. Finally, the standard deviation is obtained by taking the square root of the variance. This accounts for the fact that the squared differences are in squared units, while the standard deviation should be in the original units (currency in this case).

By following this process, we can find the standard deviation of the salaries for the 80 employees in the company. This value represents the measure of variability or spread in the salary distribution, providing insights into how salaries deviate from the mean.

The mean, standard deviation, of the average number of moths in 30 traps is approximately 0.5 ± 0.018 and is approximately 0.5 respectively. The probability that the average number of moths in 30 traps is greater than 0.4 is approximately 0.965 ± 0.01.

The mean of the average number of moths in 30 traps can be calculated as the mean of a sample of 30 trap counts, where the mean of each sample follows a normal distribution with mean 0.5 and standard deviation 0.5/sqrt(30) (using the standard error of the mean formula). Therefore, the mean of the average number of moths in 30 traps is:

mean = 0.5 ± 0.1/sqrt(30) = 0.5 ± 0.018

So the mean of the average number of moths in 30 traps is approximately 0.5 ± 0.018.

The standard deviation of the average number of moths in 30 traps can also be calculated using the standard error of the mean formula:

standard deviation = standard error of the mean * sqrt(sample size)

standard deviation = 0.5/sqrt(30) * sqrt(30) = 0.5

So the standard deviation of the average number of moths in 30 traps is approximately 0.5.

Using the central limit theorem, we can assume that the sample mean of the 30 traps follows a normal distribution with mean 0.5 and standard deviation 0.5/sqrt(30). We want to find the probability that the average number of moths in 30 traps is greater than 0.4.

To do this, we can standardize the sample mean using the formula:

z = (sample mean - population mean) / (standard deviation / sqrt(sample size))

z = (0.4 - 0.5) / (0.5/sqrt(30)) = -1.8257

Using a standard normal distribution table or calculator, we can find the probability that Z is greater than -1.8257, which is approximately 0.965. Therefore, the probability that the average number of moths in 30 traps is greater than 0.4 is approximately 0.965 ± 0.01.

The first step would be to multiply out the bracket. So, using this example we would times each item inside the bracket by 3.

As a result we would get: 3x + 12 = 18

Then we would need to move the 'x' value to one side of the equation and the rest of the equation to the other side. To move '12' onto the other side of the = sign we need to subtract 12 from both sides.

This would then bring us to: 3x = 6
