We need more info on this.
Answer:
X will equal 10 x=10
Step-by-step explanation:
First subtract 100 from both sides to get x^2-20x=-100 then find c. (-b/2)^2 is the formula. then c=100 so add 100 to both sides. x^2-20x+100=200. Then Factor. (x-10)^2=0 is what you should get. then do square root. x-10=0. So now add 10 to both sides and you get x=10. Tada!
I guess it’s A not sure tho
The value of the lower class limit of the 3rd class is; 11.0
<h3>What is the lower class Interval?</h3>
The lower class limit is lowest value of that class interval while upper class limit is highest value of that class interval.
Hours Number of Students
0.0–5.4 12
5.5–10.9 16
11.0–16.4 14
16.5–21.9 11
22.0–27.4 6
Now, the third class interval is 11.0–16.4 and from definition of lower class limit, we can say that the lower class limit of the 3rd class is; 11.0
