A new physician saw 841 clients during the first year of practice and 1072 clients during the second year of the practice. Which of the following represents the approximate percentage increase in the client volume?
A. 22%
B. 27%
C. 127%
D. 78%
Change in weight of client=new -old=1072-841= 231
Percent change=change/old*100%=231/841*100%=27.47%
The percentage change increase is about 27%
Therefore, the Correct Answer is B.

Q #1: If (D) is the distance traveled and (R) is the rate of travel, which of the following represents the relationship between D and R for the equation D=2R?
A. D is twice as much as R
B. R is twice as much as D
C. R is two than D
D. D is town more than R
Answer Explanation
Given the equation D=2R means that the get the value of D, multiply the value of R by 2. That is D is two times the value of R.

Q #3: A teacher asked all the students in the class which days of the week they get up after 8 a.m. Which of the following is the best way to display the frequency for each day of the week?
A. Histogram
B. Pie graph
C. Bar graph
D. Scatter plot
Answer Explanation
The best way to display the frequency of each day of the week when students get up after 8 a.m. is by using a bar graph. Bar graphs are well-suited for representing categorical data, where each day of the week is a separate category, and the height of each bar corresponds to the count or frequency of students waking up late on that specific day.
Note: Histograms, on the other hand, are more appropriate for visualizing continuous or numerical data and are not ideal for categorical data like days of the week. Histograms are useful for understanding the distribution of data, identifying patterns, and assessing the shape of the data distribution, such as whether it's normally distributed, skewed, or has multiple modes.
As you can see below, the Histogram is used to depict a pattern/continuous/range data. While a bar graph does just fine even with discrete data.
