debra is helping her little brother learn multiplication facts. each week, she gives him a worksheet with 40 facts. when hes done, she checks his work and records the number he got correct. eventually, debra decides to show the number correct from each week on a line plot. which of the following will it show? select all that apply. the total number of weeks the number of times debras brother got 40 out of 40 correct the lowest number of correct answers whether debras brother improved each week

Explanation:

• the number of times Debra's brother got 40 out of 40 correct: A line plot can show the frequency of a particular value (like 40 correct), so it can show how many times 40 was achieved.
• the lowest number of correct answers: By looking at all the data points (number correct each week) on the line plot, we can identify the minimum value (lowest number of correct answers).
• Note: "the total number of weeks" is not shown directly (a line plot shows data values and their frequencies, not the count of weeks as a separate element; the number of weeks would be the number of data points, but the plot doesn't "show" the total number of weeks as a labeled value). "whether Debra’s brother improved each week" is not directly shown by a line plot (which shows frequency of values, not a trend over time in a way that "improvement each week" is clear—for trend, a line graph with time on x - axis would be better). So the correct ones are the number of times Debra's brother got 40 out of 40 correct and the lowest number of correct answers.

Answer:

• the number of times Debra's brother got 40 out of 40 correct
• the lowest number of correct answers
