Option D: 
is the solution to the inequality in interval notation.
Explanation:
The number line shows the interval of numbers starting from 0 and goes on.
From the number line, it is obvious that the open circle at the point 0 indicates that we don't want to include the number 0.
Hence, in interval notation, we can write that the end values not to be included can be written with a round bracket ( )
Thus, the interval can be written as
Hence, the solution to the inequality in interval notation is
Therefore, Option D is the correct answer.

Answer:
(A)12-19
Step-by-step explanation:
To construct a frequency distribution, we follow the steps below.
1. Find the largest and smallest values.
91 and 12 respectively
Compute the Range = Maximum - Minimum=91-12=79
2. Determine the number of classes desired.
In this case, we desire 10 classes
3. Next, we find the class width by dividing the range by the number of classes and rounding up.
79÷10 = 7.9
Rounded Up, Class Width=8
4. Pick a suitable starting point less than or equal to the minimum value.
Since our minimum value is 12, we pick a class starting with 12 and give a class width of 8.
Therefore the upper and lower limits of the first class is given as:
12-19.
Answer:
q = 70°
Step-by-step explanation:
The 3 angles form a straight angle and sum to 180° , that is
q + 52° + 58° = 180°
q + 110° = 180° ( subtract 110° from both sides )
q = 70°
<span>z for $54.20 = -0.6
the percent of area associated with $54.20= 0.2743%
the z for $86.60 = 1.2
the percent of area associated with $86.60 = 0.8849%
Adding the two together, the percent of expense between $54.20 and $86.60 is 0.6106%</span>
