Answer 1

The mode of the regional charity drive meetings' attendance records is 74, since this number appears most frequently in the stem-and-leaf plot, making it the correct answer, which is option B) 74.

Step-by-step explanation:

The mode of a set of values is the number that appears most frequently. By examining the stem-and-leaf plot provided for the regional charity drive meetings' attendance records, we can determine the mode. Let's list the number of occurrences for each number:

• 31, 32, 34, 38, 38, 39
• 40, 43, 45, 47
• 56, 56
• 60, 60, 61, 63, 64, 68
• 70, 71, 73, 74, 74, 74, 77

The number 74 appears three times, which is more than any other number in the data set. Therefore, the mode of these values is 74, corresponding to answer choice B.

Answer 2

The mode of the values for on-record attendance for regional charity drive meetings is B. 74.

How to find mode?

The mode is the value(s) that occur most frequently. In the provided stem-and-leaf plot, the stem is the tens place, and the leaves are the ones place.

Look at the leaves in each stem:

For stem "3," the leaves are 1, 2, 4, 8, 8, 9.

For stem "4," the leaves are 0, 3, 5, 7.

For stem "5," the leaves are 6, 6.

For stem "6," the leaves are 0, 0, 1, 3, 4, 8.

For stem "7," the leaves are 0, 1, 3, 4, 4, 4, 7.

From this, we can see that the leaf "4" appears most frequently in the stem "7." Therefore, the mode is 74.

So, the correct answer is: B. 74
