Answer:
Step-by-step explanation:
Solve we have the inequality:
Let's solve it like a normal equation first. So, pretend the inequality is an equal sign:
Solve for x. Zero Product Property:
Add 4 to both sides for both equations:
So, our roots are at x=4 and x=4.
Since our original inequality is <em>greater than</em>, this means that our solution will be all values to the <em>left</em> of our first zero and all values to the <em>right</em> of our second zero.
Therefore, our solution is:
Simply put, our x can be anything except for 4 itself.
And we're done!
Answer:
1. Five classes in the frequency distribution
2.The mid point of the third class is 24.5
3.The total number of frequency is 100
4.The relative frequency of the third class is (20/100=0.2)
5. We use n-1 because we are dealing with a sample data
6. The mean is 24.5
7. The value of the standard deviation is 11
