A package of 8 pens costs $1.09. Milo’s work to find the unit price of the pack is shown below.



Where did Milo make his first error?
He assumed the pens are equally priced.
He wrote the unit rate incorrectly.
He made a place value error when dividing.
He multiplied instead of dividing.

Answers

He wrote the unit rate incorrectly

He put the 8 pens over the 1.09 and that means division he should have wrote to like a multiplication problem

Select the locations on the number line to plot the points 8/3 and −11/3.

Answers

Answer:

Step-by-step explanation:

8/3 is between 2 and 3 above 2.5

11.3 is between 3 and 4 above 3.5

8/3 converts to the decimal 2.666666... which means its located on the number line between 2 and 3 above 2.5.
11/3 converts to 3.6666.... which means its located on the number line between 3 and 4 above 3.5.

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."

Mr townsend needs to make 13 pairs of butterfly for customers for a play. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.

You’ll apply properties of multiplication in the following steps to find the total cost of fabric.

1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings.

2. Multiply the amount of fabric by the price per yard to find an expression for the total costs.

3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with.
