Answer:
9xn =9n
Step-by-step explanation:
For this question you will have to find your own set of data for your area, just go to weather.com or a similar site and make a set of temperatures for the next 7 days in your area. The mean can be found by adding all temperatures, then dividing their sum by the number of objects being added.
For example, if my set of temperatures were {75, 90, 83, 77, 91, 88, 80}, I would find the mean with the equation (75 + 90 + 83 + 77 + 91 + 88 + 80)/7, or 83.4
Please clarify your question because based on experience, there was never a question involving more than 1 " = "
It is going to be a greater number than 66. And a number less than 88. Hope this helps.
Answer : (0,3) U (3, ∞)
We need to find the interval(s) over which the function is decreasing
We look at the intervals of x where the graph is decreasing
Decreasing interval of the graph is the part where the graph goes down
We look at the part where the graph changes direction
In the middle inverted U shaped graph , the graph changes direction and start decreasing at x=0
the graph is decreasing till x=3
so first decreasing interval is x=0 to 3. we write it as (0,3)
After x=3 the graph starts decreasing and it goes to infinity
So the second decreasing interval is 3 to infinity . We write it as (3, ∞)
Now combine both intervals by a 'U' union
(0,3) U (3, ∞)
