Answer:none of them

Step-by-step explanation:

None of them equal 28.3. The closest is number 3, which is 26.3. Do the parenthesis, then the brackets, then add and subtract

By matching the statistical measures with their corresponding values, we have:

Median: 23.5

Mean: 22.5

Mode: 20, 24, 25, 26

Lower Quartile: 21.5

Upper Quartile: 24.5

To match the statistical measures with their corresponding values, we need to analyze the dataset and identify the appropriate measures. Here's the breakdown:

Median: The median is the middle value of the dataset when it is arranged in ascending order. In this case, since we have 12 data points, the middle two values are 23 and 24. Therefore, the median is the average of these two values, which is 23.5.

Mean: The mean is calculated by summing up all the values in the dataset and dividing by the total number of values. Adding up the given values, we get 262. Dividing this sum by 12 (the number of values), we obtain a mean of 22.5.

Mode: The mode represents the value(s) that appear(s) most frequently in the dataset. In this case, the values 20, 24, 25, and 26 all appear twice, making them the modes of the dataset.

Lower Quartile: The lower quartile divides the dataset into four equal parts, with 25% of the data falling below it. To find the lower quartile, we need to locate the value that is greater than or equal to 25% of the data. In this case, the 25th percentile falls between the values 21 and 22. The lower quartile is the average of these two values, which is 21.5.

Upper Quartile: The upper quartile divides the dataset into four equal parts, with 75% of the data falling below it. Similar to the lower quartile, we need to locate the value that is greater than or equal to 75% of the data. In this case, the 75th percentile falls between the values 24 and 25. The upper quartile is the average of these two values, which is 24.5.

The probable question may be:

"Match the statistical measures (median, mean, mode, lower quartile, upper quartile) with their corresponding values for the dataset: 20, 20, 21, 22, 23, 23, 24, 24, 25, 25, 26, 26."

Answer:

Option 4: 10d + 5

Step-by-step explanation:

Given the algebraic expression, 5(2d + 1), which represents the fines per day, d, for overdue books.

In order to determine the equivalent algebraic expression of 5(2d + 1), we must distribute 5 into the terms inside the parenthesis:

5(2d + 1)

= 5(2d) + 5(1)

[tex]\fbox{\textsf{= 10d + 5 }}[/tex]

Therefore, the equivalent expression is: 10d + 5.

No, he needs 16 inches^2 more cardboard.

Step-by-step explanation:

Take the formula and substitute values into it. 6 * 6^2

Do the exponent first to get 6 * 36, and then complete that to get 216. Since he has 200 inches of cardboard and he would need 216, that means he would need 16 more square inches to make his cube.

The frequency for 2 to 7 is 3

The frequency for 8 to 13 is 4

The frequency for 14 to 19 is 2

The grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.

We need to complete the grouped frequency distribution for the data.

In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.

Now, the frequency distribution for the given intervals is as follows:

That is, for intervals 2 to 7 the frequency is 3.

For intervals 8 to 13 the frequency is 4.

For intervals 14 to 19 the frequency is 2.

Therefore, the grouped frequency distribution for the data with the given intervals is 3, 4 and 2 respectively.

When we multiply powers with the same base, we add the powers together. This will give us:

[tex]\frac{3^8*3^4}{3^2 * 3^8} \\\frac{3^{12} }{3^{10}}\\[/tex]

When we divide the fractions with the same base then we subtract the exponents:

3^12 / 3^10 = 3^12-10 = 3^2

B. (x - 3²)(y-6)

Step-by-step explanation:

Find the expression with a value of 30;

 when x  = -1 and y = 3:

   A.  (x - 3²).y-6

           (-1 - 9).3-6 = -10 x 3 -6  = -30 - 6 = -36

 B.  (x - 3²)(y-6)

          ( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30

C.  x - 3² . (y-6) = -1 - 9.(3-6)

                         = -1-9.-3

                         = -1 - 9 x -3

                         = -1 + 27

                         = 26

D. x - 3².y-6 = -1 - 9. 3 - 6

Step-by-step explanation:

The range for the given scenario is y≥0.

Given that, Tina graphed the function on the coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Part A:

From the graph we can see that, for f(3) that is for 3 bounces the height is 4 feet.

Part B: Tina said that a possible range for the given function is y > 0.

From the graph we can see that for f(7) and f(8), the ball is almost at rest position. So the range can be y≥0.

Therefore, the range for the given scenario is y≥0.
