What is equivalent to —4 —9

Answer:

Domain: {-10, -8, -6, -4}

Range: {-5, -4, -3, -2}

Step-by-step explanation:

The domain is a set of all the x's. Here you were given points and the first number in the parenthesis is the x in (x, y). Sometimes they will give you a table or a graph. But domain is all the x's gathered together. I put them in order from small to big to be neat. There aren't any repeats here, but if there ever are repeats you don't have to list them multiple times, just once.

The range is all the y's in the points (x, y) its the second number. Gather all the y's in a set, that is the range.

Central tendency, is the term that relates to the way data tend to cluster around some middle or central value.

Measures of central tendency are summary statistics that represent the center point or typical value of a dataset. Examples of these measures include the mean, median, and mode. These statistics indicate where most values in a distribution. Mode in statistics is the number of times a number is repeated. The number which is repeated maximum times in a series of data is known as the modular number. The mode is used to compare data that has extreme figures. Central tendency simply means most scores in a normally distributed set of data tend to cluster near the center of a distribution.

Answer:

42 ,70, 98

Step-by-step explanation:

3+5+7=15

5/15*210=70

7/15*210=98

42+70+98=210.

The given statement is true. If f '(x) < 0 for 7 < x < 10, then f is decreasing on (7, 10).

If f '(x) < 0 for 7 < x < 10, then f is decreasing on (7, 10).

Declining Function: A function f is said to be decreasing on an interval I if for any two values x₁ and x₂ in I, with x₁ < x₂, then f (x₁) > f (x₂).

Since f '(x) < 0 for 7 < x < 10, it implies that the slope of the tangent line to the curve at every point in the interval (7,10) is negative. That means the graph of f is declining in that interval.

Therefore, the given statement is true. If f '(x) < 0 for 7 < x < 10, then f is decreasing on (7, 10).
This is because a negative first derivative, f'(x), indicates that the function is decreasing. The fact that f'(x) < 0 for all values of x in the given interval (7, 10) implies that the function is continuously decreasing throughout that interval.

The sums of the measures of the interior angles of the indicated convex polygons would be:

The sum of the measures of the interior angles of a convex polygon with n sides is given by the formula:

S = (n - 2) × 180 degrees

A nonagon has 9 sides, so the sum of its interior angles is:

= (9 - 2) × 180

= 1,260 degrees

A 14-gon has 14 sides, so the sum of its interior angles is:

= (14 - 2) × 180

= 2, 160 degrees

A 16-gon has 16 sides, so the sum of its interior angles is:

= (16 - 2) × 180

= 2, 520 degrees

A 20-gon has 20 sides, so the sum of its interior angles is:

S = (20 - 2) × 180

To fit a curve of the form y = Ax - 11 to the given dataset, we can use the Least Squares Method to find the value of A that minimizes the total squared error.

Using the given data points, we can calculate the corrected values y_c and the total squared error E as follows:

For the first data point (x = 1, y = 2), the corrected value y_c can be calculated as:

y_c = Ax - 11 = A(1) - 11 = A - 11

For the second data point (x = 2, y = 3), the corrected value y_c can be calculated as:

y_c = Ax - 11 = A(2) - 11 = 2A - 11

For the third data point (x = 3, y = 7), the corrected value y_c can be calculated as:

y_c = Ax - 11 = A(3) - 11 = 3A - 11

The total squared error E is given by the sum of the squared differences between the actual y-values and the corrected values:

E = (2 - (A - 11))^2 + (3 - (2A - 11))^2 + (7 - (3A - 11))^2

To find the value of A that minimizes the total squared error, we can differentiate E with respect to A, set it equal to 0, and solve for A. The value of A obtained will give the best fit curve to the dataset.

Unfortunately, without specific numerical values for the data points, it is not possible to provide the exact calculation for the value of A and the total squared error. However, the above explanation outlines the general approach for fitting a curve using the Least Squares Method.

Hint: | Add like terms in 11 x + x + 5.

x + 11 x = 12 x:

12 x + 5 = 11 x + 11

Hint: | Move terms with x to the left hand side.

Subtract 11 x from both sides:

(12 x - 11 x) + 5 = (11 x - 11 x) + 11

Hint: | Combine like terms in 12 x - 11 x.

12 x - 11 x = x:

x + 5 = (11 x - 11 x) + 11

Hint: | Look for the difference of two identical terms.

11 x - 11 x = 0:

x + 5 = 11

Hint: | Isolate terms with x to the left hand side.

Subtract 5 from both sides:

x + (5 - 5) = 11 - 5

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

x = 11 - 5

Hint: | Evaluate 11 - 5.

There are 10 students in the class who are not enrolled in either music or art.

To solve this problem, we can use the inclusion-exclusion principle.

The total number of students in the class who take music or art is given by:

18 + 26 - 2 = 42

However, this counts the 2 students who take both art and music twice, so we need to subtract them once to get the total number of students who take either music or art but not both:

42 - 2 = 40

So, 40 students in the class take either music or art.

To find the number of students who are not enrolled in either music or art, we subtract this from the total number of students in the class:

50 - 40 = 10

Therefore, there are 10 students in the class who are not enrolled in either music or art.

Answer:

He is not correct as the ratios are;

First ratio is 4:5,

Second ratio 11:13

Which are different values

Step-by-step explanation:

The number of correct questions Levi answered = 8 questions

The number of questions in the game = 10

The ratio of correctly answered questions to total number of questions in the first 10 question is given as follows

Correctly answered questions : Total number of questions = 8:10

Which can be simplified as 8:10 = 8/2:10/2 = 4:5

The number of correct questions Levi answered in the next three turns = 3 questions

The total number of questions attempted by Levi becomes 10 + 3 = 13 questions

The total number of correct answers given by Levi = 8 + 3 = 11 correct answers

The new ratio of correctly answered questions to total number of questions is therefore;

New correctly answered questions : Total number of questions = 11:13.

Therefore, the ratios do not remain the same as 4:5 ≠ 11:13.

To find the value of x, we calculate the average of the sample observations. Summing up the observations and dividing by the total number of observations, we get:

x = (125 + 122 + 126 + 100 + 155 + 132 + 121 + 118 + 114 + 125 + 142 + 2 + 130 + 110 + 140 + 129 + 3) / 17 = 114.118 seconds (rounded to three decimal places).b) To find the value of R, we calculate the range of each sample by subtracting the minimum observation from the maximum observation. Then we find the average range across all samples:R = (155 - 100 + 142 - 2 + 140 - 110 + 132 - 114 + 142 - 3) / 5 = 109.2 seconds (rounded to three decimal places).

c) The Upper Control Limit (UCL) and Lower Control Limit (LCL) using 3-sigma can be calculated by adding and subtracting three times the standard deviation from the average:UCL = x + (3 * R / d2) = 114.118 + (3 * 109.2 / 1.693) = 348.351 seconds (rounded to three decimal places).LCL = x - (3 * R / d2) = 114.118 - (3 * 109.2 / 1.693) = -120.115 seconds (rounded to three decimal places).

d) The Upper Control Limit Range (UCLR) and Lower Control Limit Range (LCLR) using 3-sigma can be calculated by multiplying the average range by the appropriate factor:UCLR = R * D4 = 109.2 * 2.115 = 231.108 seconds (rounded to three decimal places).LCLR = R * D3 = 109.2 * 0 = 0 seconds.
