Which of the following values is the greatest?
A. 4.25
B. 10/3
C. 4.4
D. 9/2
To compare the given values, convert them to the same number format. In this case, convert the given fractions into equivalent decimals.
10/3=3.3333…..
9/2=4.5
Thus, the numbers become 4.25, 3.333…, 4.4, 4.5
Now arranging them in ascending order becomes 3.333…., 4.25, 4.4, 4.5
From the above, 4.5 is the greatest value.
Therefore, the Correct Answer is D.

Q #1: The table shows healthcare spending per capita in a group of African nations. Based on this information, which of the following countries had the greatest change in dollars spent per capita from 2013 to 2015?
A. Eritrea
B. Sudan
C. Tanzania
D. Kenya
Answer Explanation
To find a solution to this, we need to find the change in spending between the year 2013 and 2015 for each country. Change is difference in amount spent in 2015 and 2013 for each country:
Sudan=$(24-17)= $7
Eritrea=$(42-56)= - $14
Nigeria = $(21-16)= $5
Tanzania =$(81-68) = $13
Rwanda = $(24-27) =-$3
Kenya = $(88-81) = $8
A Minus sign means a decrease in spending. From the above calculations, Eritrea had the GREATEST change in dollars spent while Rwanda had the LEAST change in dollars spent.

Q #2: Which of the following is the best description for the data set below? 1, 1, 2, 2, 2, 2, 3, 3, 7, 7, 8, 8, 8, 8, 9, 9
A. Uniform
B. Right-skewed
C. Bimodal
D. Left-skewed
Answer Explanation
To solve this problem, we need to find the mean, mode, and median of the above data set.
From the data set, the mode of the data is 2 and 8. They are the most occurring elements in the data set.
The mean of data is the total divided by the number of elements
Total=1+ 1 + 2+ 2+ 2+ 2+ 3 +3+ 7+ 7+8+8+ 8+ 8+ 9+9=80
Number of elements=16
Mean=80/16=5
Median will fall in between the (N/2)th and (N/2+1)th position
(N/2)th =16/2 =8th position and (16/2+1)th =9th position
Since the data is arranged in ascending order as below
1, 1, 2, 2, 2, 2, 3, 3, 7, 7, 8, 8, 8, 8, 9, 9
Element in 8th position = 3
Element in 9th position =7
So the median average of the two elements=(3+7)/2=5
Now the data could be presented as follows in the distribution curve
This is because the data set has two modes, meaning the data is bimodal.

Q #3: Which of the following is 31% of 426?
A. 425.69
B. 132.06
C. 13.7
D. 0.07
Answer Explanation
First convert 31% to a decimal before working on the problem
31%=31/100=0.31
Thus, 31% of 426=0.31*426=132.06
