7. mode: 45, 40, 47, 50, 45, 49, 40, 46

7. mode: 45, 40, 47, 50, 45, 49, 40, 46

7. mode: 45, 40, 47, 50, 45, 49, 40, 46

Answer

Explanation:

Step1: Recall mode definition

The mode is the number that appears most frequently in a data - set.

Step2: Count frequencies

Count the number of times each number appears:

45 appears 2 times.
40 appears 2 times.
47 appears 1 time.
50 appears 1 time.
49 appears 1 time.
46 appears 1 time.

Step3: Determine mode

Since 40 and 45 both appear 2 times (more frequently than the other numbers), the data - set is bimodal.

Answer:

40, 45
