The answer is [A]: "Section A: "7.0 - 7.5" — in the figure shown" .

Explanation:
________________________________________________________
The question asks:
________________________________________________________
"In which section of the number line is √55?"
________________________________________________________
 We know that: 7² = 49 ; 8² = 64 .

So, 7 < √55 < 8 ; So, √55 will be in between 7 and 8.

So, √49 < √55 < √64 .

55 - 49 = 6 .

64 - 55 = 9 .

 So, there is greater difference between the radicands in

 √64 and √55 ; compared to the difference in radicands between

 √49 and √55 .
________________________________________________
 This tells us that the correct answer is:
________________________________________________
 [A] { in the figure shown: "7.0 - 7.5" } ;
________________________________________________
 rather than: [B]: { "7.5 - 8.0" } .

Step-by-step explanation:

We are dealing with theoretical probability. This means that our probability of said outcome is

$\frac{x}{y}$

where x is the outcome we want, and y is the total number of outcomes possible.

28. There is 3 triangles out of 6 polygons so the probability is 1/2.

29.There is 1 Pentagon so the probability is 1/6.

30. This is a complement to question 28. A complement is the inverse of the problem. A complement and its original add to 1 so the probability of both getting a triangle is 1/2.

31. There is 4 non quadraletrial so the probability is 2/3.

32. There is 3 figures that has more sides than three so 1/2 is the probability.

33.There is only multi right angles figures so 1/2 is the probability.

34. There is 30 days in April so the probability it's the 29th is

$\frac{1}{30}$
