Answer: 7
Step-by-step explanation:
First order the numbers by least to greatest
2, 3, 5, 9, 12, 21
Then find the number inbetween
In this case it's a tie between 5 and 9.
Find the average of those two numbers
The average is 5+9/2 = 7
Median is 7
The answer is 35 7/8. We know that to get the mean, you must add up all the numbers and divide by the amount of numbers. Set up the equation (36 3/4 +36 3/8+37 1/2+n)/4 = 36 5/8. After you solve for n, the missing number, you should get 35 7/8.
The number 1000 less than 921,438 is 920,438. What you do is take 921,438 and subtract 1000 from it.
