Answer:
Commutative Property
Step-by-step explanation:
The property of multiplication that is being demonstrated is known as Commutative Property. This property basically shows that when multiplying two numbers the actual order in which they are multiplied does not matter and does not affect the result at all. For example, the in this scenario to get the total number of oranges we have to multiply the number of bags by the number of oranges in each bag, but whatever way we do this they equal the same
2 bags * 3 oranges per bag = 6 oranges
3 bags * 2 oranges per bag = 6 oranges
Therefore,
2 * 3 = 3 * 2
Answer: 95.45 %
Step-by-step explanation:
Given : The distribution is bell shaped , then the distribution must be normal distribution.
Mean :
Standard deviation :
The formula to calculate the z-score :-
For x = 13
For x = 19
The p-value =
In percent,
Hence, the percentage of data lie between 13 and 19 = 95.45 %

Given a table, with an input (x) and output (y) , you could actually use the slope formula to get the rate of change because slope is the same thing as rate of change. If you recall, the slope formula is (y2-y1)÷(x2-x1)
Just pick two points from the chart and plug them in and that is your rate of change
2 x 117
3 x 78
6 x 39
9 x 26
13 x 18
