2) The students in a class collected data on the number of minutes per
day some kids spend brushing their teeth. Their data is shown in the
dot plot below. Which statement correctly describes these data?

A. The median is 0.5 and the mean is less than the median.
B. The median is 0.5 and the mean is greater than the median.
C. The median is 1.5 and the mean is less than the median.
D. The median is 1.5 and the mean is greater than the median.

Based on the data that are given in the question, the correct option will be D. The median is 1.5 and the mean is greater than the median.

From the information given, it can be depicted that when the numbers are arranged in ascending or descending order, the number in the middle which is the median will be 1.5.

Now, the mean will be:

= (0.5 + 1.5 + 2.5 + 5.4) / 6

= 9.9/6

= 1.65

Therefore, median is 1.5 and the mean is greater than the median.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
