Statistical significance refers to the likelihood that the association between two variables is not due to chance alone. In other words, it is a measure of the probability that the observed relationship between two variables is real and not just a result of random variation or sampling error.

When analyzing data, researchers often use statistical tests to determine whether there is a significant association between two variables. A p-value is calculated, which represents the probability that the observed relationship between the variables is due to chance. If the p-value is less than a predetermined threshold (usually 0.05), the results are considered statistically significant, and the researchers can conclude that there is a real association between the variables. It's important to note that statistical significance does not necessarily imply practical significance. Just because a relationship is statistically significant does not mean that it is important or meaningful in real-world terms. Additionally, statistical significance only tells us about the strength of the relationship between two variables, not about causation or directionality. Therefore, it is always important to interpret statistical significance in the broader context of the research question and study design.

Answer:

Each poodle requires 1 balloon(s) and each poodle requires 3 balloons.

Step-by-step explanation:

The equations that should be formed are:

3x + 3y = 12

3x + 2y = 9

In this scenario, x is the number of balloons required for a poodle, and y is the number of balloons required for a giraffe.

The question says that it should be solved using elimination.

This means that we have to completely reduce a variable to find the answer of the other remaining value. Since in both equations the coefficient of x is 3, they can cancel out when we subtract one from the other:

  3x + 3y = 12

-  3x + 2y = 9

-----------------------

            y = 3

This means that the number of balloons required for a giraffe is 3.

We can then put in this value of y, 3, into the equation to solve for x.

3x + 3 (3) = 12

3x + 9 = 12

3x = 12 - 9

3x = 3

 x = 1

This reduces into the number of balloons required for a poodle to be 1.

We can confirm by plugging it in into the other equation.

3x + 2 (3) = 9

3x + 6 = 9

3x = 9 - 6

3x = 3

x = 1

After confirming, this should be the answer.

Hopefully this helps!

To determine if the bolts vary by more than the required variance, we can conduct a hypothesis test. The null hypothesis (H₀) states that the variance of the bolts is equal to or less than the required variance (σ² ≤ 0.025), while the alternative hypothesis (H₁) states that the variance is greater than the required variance (σ² > 0.025).

Next, we need to determine the critical value(s) of the test statistic. Since we are testing for variance, we will use the chi-square distribution. For a one-tailed test with α = 0.01 and 14 degrees of freedom (n-1), the critical value is 27.488.

Now, we can compare the test statistic to the critical value. The test statistic is calculated as (n-1) * s² / σ², where n is the sample size (15), s² is the sample variance (0.1587²), and σ² is the required variance (0.025).

If the test statistic is greater than the critical value, we reject the null hypothesis and conclude that the bolts vary by more than the required variance. Otherwise, we fail to reject the null hypothesis.

I will do the first example, by explaining how to graph it. Then you can do the second example.

\(f(x) = x^3-10x^2+28x-24\)

We start by determining the the x-intercepts, by letting y = 0:

\(x^3-10x^2+28x-24=0,\\\left(x-2\right)^2\left(x-6\right)=0,\\x=2,\:x=6\)

The x-intercepts of the graph are (2, 0) and (6, 0) respectively. Now we determine the y-intercepts by letting x = 0:

\(f\left(x\right)=\left(0\right)^3-10\left(0\right)^2+28\left(0\right)-24 = - 24\)

So the y-intercept is (0, -24). But remember we need one more point, as there has to be a transition between the x-intercepts. This is the minimum of the graph. To determine this, we take the derivative of the function, and then equate it to 0 to find the "critical points." :

\(\frac{d}{dx}\left(x^3-10x^2+28x-24\right)\\\\ =>\frac{d}{dx}\left(x^3\right)-\frac{d}{dx}\left(10x^2\right)+\frac{d}{dx}\left(28x\right)-\frac{d}{dx}\left(24\right)\\\\=> 3x^2-20x+28-0\\=> 3x^2-20x+28\)

Now we equate this to 0, and apply the quadratic equation. In this case we can actually factor it :

\(3x^2-20x+28=0,\\\left(x-2\right)\left(3x-14\right)=0,\\\\x=2,\:x=\frac{14}{3}\)

x = 2 is our maximum, or our x-intercept (2, 0). Therefore we have to take 14/3 as our minimum, and determine the y-value:

\(f\left(x\right)=\left(\frac{14}{3}\right)^3-10\left(\frac{14}{3}\right)^2+28\left(\frac{14}{3}\right)-24\\\\= -\frac{256}{27}\)

Minimum: (14/3, -256/27)

The series of transformations consists of a translation down two units and a reflection across the y-axis. Thus, option C is correct.

The points A and C will be replaced with D and F, respectively, by a reflection across the y-axis, leaving B in the same location. As a result, the image of AABC is given, A'D'BCF.

The final image, denoted by the letters ADEF, is produced by translating all the points of the image A'D'BCF' down by two units.

ADEF and AABC are not in the same location, even if they are the same height and shape.

The first thing we notice is that ADEF and AABC are oriented the same way, so we don't need to rotate them. Instead, by utilising a reflection over the y-axis, we may swap out the places where A and B were for D and E, respectively.

A'B'C' is still not in the appropriate place even though it is 2 units to the left of ADEF. Hence, we must translate 2 units down in order to position A'B'C' where ADEF is.

Therefore, A reflection across the y-axis and a translation 2 units down.

Range describes the y-values of a graph.

Range

Range is the y-values that a graph covers. Remember that the y-values are found on the vertical axis. If the graph is not continuous, then the values between the points are not included in the range. Similar to the range, the domain of a graph is the x-values that a graph covers. If there is a coordinate point with a y-value, then that y-value should be included in the range.

Finding Range

In order to find the range, we need to find all the unique y-values of the graph. Additionally, the range is given in numerical order. This means starting from the least value and going up to the greatest. The lowest y-value is 1, then 2, and finally 4. Even though there are two points where y = 2, we are only looking for unique values. This means that the range is (1,2,4).

Step-by-step explanation:

The midpoint of a line segment has coordinates that are the average of the end-point coordinates.

  M = (X + Y)/2 = ((-3, 4) +(5, 6))/2 = (-3+5, 4+6)/2 = (2, 10)/2

  M = (1, 5)

The midpoint is (1, 5).

The equation that represents the relationship in the table is y = x + 2.75.

To determine the equation that represents the relationship between the amount of money Jack earns, x, and the amount of money Julie earns, y, we need to identify the pattern in the data.

Looking at the given values, we can see that as Jack's earnings increase by $1.25, Julie's earnings increase by $1.25 as well.

This indicates a constant rate of change, or slope, between the two variables.

Using the point-slope form of a linear equation, we can write the equation as:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is any point on the line.

We can choose any point from the table, such as (87.50, 90.25), to substitute for (x1, y1).

The slope, m, is the change in y over the change in x, which is:

m = (91.50 - 90.25) / (88.75 - 87.50) = 1.25 / 1.25 = 1

Substituting the values into the point-slope form, we get:

y - 90.25 = 1(x - 87.50)

Simplifying, we get:

y - 90.25 = x - 87.50

y = x + 2.75.
