Using the concept of domain, the domain of (f.g)(x) is given by:
{x ∈ ℝ | x ≠ 3}
---------------------
- The domain of a function is given by all possible input values, that is, <u>on a graph, all values that the x-axis assumes.</u>
- In the graph, <u>function f assumes all real values.</u>
- Function g is not defined for x = 3, thus, it's domain is all real values except 3.
- Thus, the multiplication, as
, will also not be defined at x = 3, and the domain of the multiplication is:
{x ∈ ℝ | x ≠ 3}

Answer:
Square
Step-by-step explanation:
6 * 
= 600,000,000
I would put a decimal or dot to the right of 6 and count 8 zeros places to the right.
6. 0 0 0 0 0 0 0 0.
Answer:
Dot plot, because a small number of scores are reported individually.
Step-by-step explanation:
Histogram is usually used when a group of data to be represented is usually large and given in ranges or intervals.
However, for a data set, such as the scores of the group of 12 students who participated in a dance competition are reported individually, and not as ranges or intervals, a dot plot would best for representing this small number of scores.
See attachment below to see how we can easily represent the given scores of the students on a dot plot. Each dot represents a score value for each student.
Answer:
E green team, because their score starts from 75 to 90, whiles the red starts from 80 to 85
Answer:
The minimum sample size required to create the specified confidence interval is 1024.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
What is the minimum sample size required to create the specified confidence interval
This is n when 
.
The minimum sample size required to create the specified confidence interval is 1024.
