(x +y) + Z commutative property of addition

goldenfox [79]

Answer:

Step-by-step explanation:

commutative property of addition : x + y = y + x

example : 2+3 =5 and 3+2 =5 then 2+3=3+2

associative property of addition

x + y + z = (x + y) + z = x + (y + z)

example: 2+3+4 = (2+3)+4 = 5 + 4 =9

2+3+4 = 2+(3+4) = 2 + 7 = 9

A population of small bottles and their contents has the following weights (in grams): 4, 2, 5, 4, 5, 2, and 6. What is the vari

Ahat [919]

Answer:

D. 2.33.

Step-by-step explanation:

Given;

the weight distribution of the bottles = 4, 2, 5, 4, 5, 2, and 6

sum of the weights = 28

the mean (x) = 28/7

x = 4

the sum of square of the mean deviation is calculated as:

= (4 - 4)² + (2 - 4)² + (5 - 4)² + (4 - 4)² + (5 - 4)² + (2 - 4)² + (6 - 4)²

= 0 + 4 + 1 + 0 + 1 + 4 + 4

= 14

$the \ variance \ is \ calculated \ as:\\\\\sigma ^2 = \frac{\sum (x-\bar x)^2}{n-1} \\\\\sigma ^2 = \frac{14}{7-1} = \frac{14}{6} = 2.33$

Therefore, the correct answer is D
