Example Question #11 : Tables
Washington Elementary School has seven eighth-grade teachers; each teacher has the number of boys and girls listed above.
An eighth-grade girl has transferred from another school. It is desired that no teacher have more than thirty students overall or eighteen girls in his or her class. Of the seven teachers, how many could accept the girl into his or her class?
One
Seven
Six
Two
One
We can eliminate Cermak and Georghiou immediately since each has eighteen girls in his class. Of the other five:
Adams has 
Boyer has 
Donovan has 
Esterhaus has 
Finnegan has 
Only Mrs. Finnegan's class could accept the new girl without going against the wishes of the school. The correct response is one.
Example Question #12 : Tables
A popular word game uses one hundred tiles, each of which is marked with a letter or a blank. The distribution of the tiles is shown above, with each letter paired with the number of tiles marked with that letter. Notice that there are two blank tiles.
What percent of the tiles are marked with consonants?
Note: for purposes of this question, "Y" is a consonant.
Counting the number of tiles with vowels is much easier.
Out of the 100 tiles, there are nine "A" tiles, twelve "E" tiles, nine "I" tiles, eight "O" tiles, and four "U" tiles. This is a total of
tiles out of 100.
There are also two blanks, so the number of tiles marked with consonants is
56 out of 100 is 56%.
Example Question #11 : Tables
Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period.
Between which two consecutive days did the high temperature show an increase?
Between Tuesday and Wednesday
Between Wednesday and Thursday
Between Monday and Tuesday
Between Thursday and Friday
Between Monday and Tuesday
Examining the high temperature line, it can be seen that, among the four choices given, only the segment connecting Monday to Tuesday has a positive slope (lower left to upper right).
Therefore, of the four choices, Monday to Tuesday is correct.
Example Question #14 : Tables
A popular word game uses one hundred tiles, each of which is marked with a letter or a blank. The distribution of the tiles is shown above, with each letter paired with the number of tiles marked with that letter. Notice that there are two blank tiles.
What percent of the vowel tiles are marked with an "A"? (Nearest whole percent).
Note: for purposes of this question, "Y" is a consonant.
There are nine "A" tiles, twelve "E" tiles, nine "I" tiles, eight "O" tiles, and four "U" tiles. This is a total of
vowel tiles.
Out of these tiles, 9 are marked with an "E"; this is
This rounds to 21%.
Example Question #21 : Data Analysis And Probability
Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period. The temperatures at left are given in degrees Fahrenheit.
Temperatures given in degrees Fahrenheit can be converted to the Celsius scale using the formula
Express the highest temperature of the week in degrees Celsius (nearest whole degree).
As can be seen below, the highest temperature for the week was 78 degrees Fahrenheit, on Tuesday.
To convert this to degrees Celsius, set 
Example Question #22 : Data Analysis And Probability
Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period.
The high temperature on Wednesday occurred at 1:00 PM; the low temperature, at the end of the day (midnight). The temperature drop was steady. What was the average drop in temperature per hour between 1:00 PM and midnight (nearest tenth of a second)?
2.5 degrees per hour
1.7 degrees per hour
1.3 degrees per hour
2.1 degrees per hour
1.3 degrees per hour
As can be seen in the diagram below, the high and low temperatures on Wednesday were, respectively, 74 and 60 degrees, for a drop of 
This drop occurred over a period of 
degrees per hour. The quotient of this is seen below:
This rounds to 1.3 seconds.
Example Question #23 : Data Analysis And Probability
A popular word game uses one hundred tiles, each of which is marked with a letter or a blank. The distribution of the tiles is shown above, with each letter paired with the number of tiles marked with that letter. Notice that there are two blank tiles.
All of the consonant tiles are placed in a box. It is desired to place just enough of the vowel tiles so that the probability of drawing a vowel is 
Note: for purposes of this question, "Y" is a consonant.
There are nine "A" tiles, twelve "E" tiles, nine "I" tiles, eight "O" tiles, and four "U" tiles. This is a total of
There are also two blanks, so the number of tiles marked with consonants is
For the probability of drawing a vowel tile to be 
If we let 
Example Question #24 : Data Analysis And Probability
In a class of 
| Number of Siblings | Number of Students with the Specific Number of Siblings |
| 0 | 5 |
| 1 | 9 |
| 2 | 4 |
| 3 | 2 |
What is the mode for the number of siblings for this class?
Recall that the mode is the number that appears most often in a data set.
For this class,
