Find the Mean: 6, 8, 10, 12, 14, 16, 18, 20
Step 1: Add all the numbers:
6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 104
Step 2: Divide the total by the number of values:
There are 8 numbers.
104 ÷ 8 = 13
Simplify: 6 + 2 × (5 – 3)²
6 + 2 × 4 = 6 + 8 = 14

Samantha is hiking up a mountain.
She starts at –250 feet (below sea level).
Then she climbs 450.5 feet.
After a break, she descends 175.25 feet.
🧮 What is Samantha’s elevation now?
Step 1: Start at –250
Step 2: –250 + 450.5 = 200.5
Step 3: 200.5 – 175.25 = 25.25
✅ Final Answer: Samantha’s elevation is 25.25 feet above sea level.
Evaluate: 3.8 + 69.84/9.7 - 2.8 x .73
First: 69.84 / 9.7 = 7.2
Second: 2.8 x .73 = 2.044
Third: 3.8 + 7.2 = 11
Fourth: 11 - 2.044 = 8.956
Final Answer: 8.956
Data Set: 4, 7, 9, 7, 10, 8
Find the following:
Median
Mode
Mean
1. Median: With an even number of values, take the average of the two middle numbers:
Middle numbers: 7 and 8
Median = (7 + 8) ÷ 2 = 7.5
2. Mode: Which number appears most often?
7 appears twice, all others appear once
Mode = 7
3. Mean: Add all the numbers:
4 + 7 + 7 + 8 + 9 + 10 = 45
Divide by number of values (6):
45 ÷ 6 = 7.5
