Answer:

141 Degrees

Step-by-step explanation:

Sum of interior angles of a polygon = \((n-2) \times 180^{\circ}\)

(where n is the number of sides)

The given figure has 8 sides, therefore:

⇒ sum of interior angles = (8 - 2) × 180°

                                          = 6 × 180°

                                          = 1080°

To find x, sum all the given angles, equate to 1080°, then solve for x:

⇒ x + 162 + (x - 12) + (x + 30) + x + 133 + (x + 16) + 126 = 1080

⇒ 5x + 455 = 1080

⇒ 5x = 625

⇒ x = 125

Therefore, (x + 16) = 125 + 16 = 141°

If the value stated by a null hypothesis is within the confidence interval, then the decision would have likely been to retain the null hypothesis.

In hypothesis testing, the null hypothesis represents the default assumption or the claim that there is no significant difference or relationship between variables. The confidence interval, on the other hand, provides a range of plausible values for the population parameter based on sample data. If the value stated by the null hypothesis falls within the confidence interval, it means that the null hypothesis value is considered plausible or consistent with the observed data.

In this case, there is insufficient evidence to reject the null hypothesis, and the decision would be to retain it. On the other hand, if the null hypothesis value is outside the confidence interval, it suggests that the null hypothesis is unlikely, and the decision would be to reject it in favor of an alternative hypothesis.

The linear equation is y = -0.58x + 10.072. The value of \(R^2\) is 0.8818.

To find the linear equation between average concentration and distance to the pollution source, we can use the method of least squares to find the slope and the y-intercept of the line.

The slope (m) can be calculated as follows:

m = (NΣxy - ΣxΣy) / (NΣx^2 - (Σx)^2)

where N is the number of data points, x is the distance to the pollution source, y is the average concentration, Σxy is the sum of the products of x and y, Σx is the sum of x, and Σy is the sum of y.

The y-intercept (b) can be calculated as follows:

b = (Σy - mΣx) / N

Plugging in the given data, we get:

N = 5

x = [2, 4, 6, 8, 10]

y = [11.5, 10.2, 10.3, 9.68, 9.32]

Σx = 30

Σy = 41.72

Σxy = 106.72

So, m = (5 * 106.72 - 30 * 41.72) / (5 * 174 - 30^2)

=> -0.58

And b = (41.72 - -0.58 * 30) / 5

=> 10.072

Therefore, the linear equation is:

y = -0.58x + 10.072

The coefficient of determination (r^2) is a measure of how well the linear model fits the data. It is defined as the ratio of the explained variance to the total variance.

r^2 = (Explained variance) / (Total variance) = 1 - (Residual variance) / (Total variance)

where residual variance is the sum of the squares of the differences between the actual y values and the predicted y values from the model.

We can calculate r^2 as follows:

\(y_{pred} = -0.58x + 10.072 \\ residuals = y - y_{pred}\\ residual_{variance} = sum(residuals^2)\\ total_{variance} = sum((y - mean(y))^2)\\ r_{squared} = 1 -\frac {residual_{variance}}{ total_{variance}}\)

Plugging in the given data, we get:

\(residual_{variance} = 0.9048\\ total_{variance} = 7.6584\\r_{squared} = 1 -\frac {0.9048} {7.6584}\\ r_{squared} = 0.8818\)

Therefore, r^2 = 0.8818

This means that 88.18% of the variance in the average concentration can be explained by the distance to the pollution source. This is a relatively high value, which indicates a strong linear relationship between the two variables.

Answer:

The indifference point is 100 minutes.

Step-by-step explanation:

Giving the following information:

Plan a cost $23 plus an additional $.08 for each minute of calls.

Plan B cost $19 an additional $.12 for each minute of calls.

First, we need to establish the total cost formula for each plan:

Plan A= 23 + 0.08*x

Plan B= 19 + 0.12*x

x= number of minutes

Now, to calculate the indifference point, we equal both formulas and isolate x:

23 + 0.08x = 19 + 0.12x

4 = 0.04x

100= x

The indifference point is 100 minutes.

Prove:

Plan A= 23 + 0.08*100= $31

Plan B= 19 + 0.12*100= $31

The area of the parallelogram with vertices K(1,2,3), L(1,3,6), M(3,8,6), and N(3,7,3) is approximately 29.1547.

To find the area of the parallelogram, we need to find the length of one of its base vectors and the perpendicular height.

Let's first find one of the base vectors. We can take KL or MN as the base vector. Let's take KL.

The vector KL = L - K = (1, 3, 6) - (1, 2, 3) = (0, 1, 3).

Next, we need to find the perpendicular height of the parallelogram. We can do this by finding the cross-product of KL and KM, and then taking its magnitude.

The vector KM = M - K = (3, 8, 6) - (1, 2, 3) = (2, 6, 3).

Taking the cross product of KL and KM, we get:

KL x KM = |i j k|

|0 1 3|

|2 6 3|

= i(18) - j(6) + k(-2)

= (18, -6, -2)

The magnitude of KL x KM is:

\(|KL x KM| = √(18^2 + (-6)^2 + (-2)^2) = √(340) = 2*√(85)\)

Therefore, the area of the parallelogram is:

Area = base x height = |KL| x |KL x KM| = \(√(0^2 + 1^2 + 3^2) * 2√(85) = 2√(10)√(85) = 2√(850) ≈ 29.1547\)

So, the area of the parallelogram with vertices K(1,2,3), L(1,3,6), M(3,8,6), and N(3,7,3) is approximately 29.1547.

Answer:

x=100

Step-by-step explanation:

a=5√(2)

2a=2√(2x)

Multiply the first equation by 2 on both sides to get:

2a=2*5√(2)=10√(2)

Now, since we have 2a on the left sides of both equations, we can solve this.

10√(2)=√(2x)

We can rewrite √(2x) as √(2) * √(x) and divide by √(2) on both sides.

10=√(x)

Square on both sides to get:

100=x

So x=100. Hope I could help you!

Answer:

The mean increases from 9 to 10 when there are 15 students at the next meeting of the club. This is because the mean is calculated by adding all the data values together and then dividing by the total number of students. When the number of students increases from 9 to 15, the sum of the data points increases while the total number of students also increases, resulting in an increase in the mean.

Including the 15 students in the data may increase or decrease the mean. This is because the mean is calculated by adding all the numbers in a set and dividing by the quantity. Adding a new number to the set (in this case 15) thus changes the mean. If the new number is greater than the current mean, the mean will increase; if it's less, the mean will decrease.

The question is related to the concept of mean in mathematics which is the average of a set of numbers. If there are more students attending the club meeting, including this value can cause the mean to change.

Consider a set of values. The mean of these values is calculated by adding all these values together and dividing by the number of values. If we add a new value (in this case the 15 students) to our set, it will affect the calculation of the mean. If the new value is higher than the current mean, it would increase the mean. If it's less, it would decrease the mean. Therefore, the mean could increase or decrease when including the 15 students in the data set.

Let's say the mean value before adding 15 was 9 and we had 10 values in our set. The total would be 9*10=90. When we add 15, the total becomes 105 and the new mean becomes 105/11, which is close to 9.5. Thus, by adding 15 to our data set, the mean has increased from 9 to 9.5.

Answer: The grade of the hill = 50%

Step-by-step explanation:

The grade is the slope( expressed as a percent). To evaluate the slope we divide the rise by the run.

Given: A hill on a hiking trail goes up to 69 feet over a distance of 138 feet.

So, rise= 69 feet   , run = 138 feet.

The grade of the hill = \(\dfrac{rise}{run}\times100\)

\(=\dfrac{69}{138}\times100=50\%\)

Hence, the grade of the hill = 50%

It is true to state that Lin tried to reflect triangle ABC across line t.

She knows something went wrong because the image isn’t congruent to the original figure.

1) Note that  Lin probably understands that the image needs to be the same distance away from the line as the original figure.

2) Lin doesn’t understand that the segments that connect the original figure to the image need to be equidistant to the line.

In mathematics, a reflection is a transformation that flips a figure over a line or plane.

The reflection of a point or shape across a line or plane is the same distance from that line or plane as the original point or shape. This is known as equidistance.

Therefore, reflection and equidistance are closely related in that a reflected point or shape is equidistant from the line or plane of reflection as the original point or shape.

To calculate \(\frac{{f(x+h) - f(x)}}{h}\) for the function \(f(x) = ax^3\), we need to substitute the expressions into the formula and simplify.

\(f(x+h) = a(x+h)^3\\\\f(x) = ax^3\)

Now we can calculate the difference:

\(f(x+h) - f(x) = a(x+h)^3 - ax^3\)

Expanding \((x+h)^3\):

\(f(x+h) - f(x) = a(x^3 + 3x^2h + 3xh^2 + h^3) - ax^3\)

Simplifying:

\(f(x+h) - f(x) = ax^3 + 3ax^2h + 3axh^2 + ah^3 - ax^3\)

The terms \(ax^3\) cancel out:

\(f(x+h) - f(x) = 3ax^2h + 3axh^2 + ah^3\)

Now we can divide by h:

\(\frac{{f(x+h) - f(x)}}{h} = \frac{{3ax^2h + 3axh^2 + ah^3}}{h}\)

Canceling out the common factor of h:

\(\frac{{f(x+h) - f(x)}}{h} = 3ax^2 + 3axh + ah^2\)

Now, we evaluate this expression again by setting h = 0:

\(\frac{{f(x+h) - f(x)}}{h} = 3ax^2 + 3ax(0) + a(0)^2\)

\(= 3ax^2\)

Therefore, when we evaluate the expression by setting h = 0, we get \(3ax^2\).
