Question

LAST ONE GUYS PLEASE HELP

Answer 1

Answer:

B. 23

Step-by-step explanation:

Median is the middle value in a set of numbers. To find the Median, you have to arrange the values from ascending to descending and cross out the numbers one end to the other. But in this problem we don't have to arrange the values because it's already arranged in order.

12, 18, 21, 25, 30, 43

When crossed out, two numbers were found at the end, but those two numbers cannot be the median. If there are 2 numbers left after you cross them out, you have to add both values and divide it by the number of values there are left. In this case, there are 2 values left, so you have to divide by 2.

21 + 25 = 46 ÷ 2

= 23

Therefore the median of this data set is 23.

Answer 2

Answer:

B

Step-by-step explanation:

The median is the middle number.

So the setup is now like this:

12,18,21,25,30,43

Since 21 and 25 is the middle, find the average:

21+25 is 46

46/2 is 23
