Mean: add all the numbers, then dived the sum by hwo many numbers there are.
72.3 + 74.5 + 81.1 + 72.3 + 75.6 + 79 = 754.8
754.8 ÷ 6 = 75.8
Mean = 75.8°

Median: Put all the number in order from lowest to highest. The middle number is the median. If there are two numbers in the middle, add them then divide the sum by 2.
72.3, 72.3, 74.5, 75.6, 79, 81.1

2. For a particular model of a car, a dealer offers 3 sizes of engines, 2 types of stereos, 18 body
Gnesinka [82]

The given details follow the product rule. The different model of the car available are 756.

Given that:

Engines = 3

Stereos = 2

Body=18

Color = 7

The different possibility is calculated using the following product rule:

Total =Engines \times Stereos \times Body \times Color

So, we have:

Total = 3\times 2\times 18 \times 7

Total = 756

Hence, there are 756 different models available.

N P r = (n!)/((n-r)!)
8 P 4 = (8!)/((8-4)!)
8 P 4 = (8!)/(4!)
8 P 4 = (8*7*6*5*4!)/(4!)
8 P 4 = 8*7*6*5
8 P 4 = 1680

The final answer is 1680
