Example Question #1 : How To Use A Venn Diagram
Let set , the set of all natural numbers.
= {
|
is a multiple of 6 }
= {
|
is a multiple of 9 }
Which of the following numbers would appear in the gray region of the Venn diagram?
The gray area represents the portion of that is not in
- in other words, all multiples of 9 that are not also multiples of 6.
Therefore, 4,572, 3,438, and 8,544 can be eliminated.
, so 9,349 can be eliminated because it isn't a multiple of 9.
and
, so, as both a nonmultiple of 6 and a multiple of 9, 4.077 is the correct choice.
Example Question #2 : Venn Diagrams
If two events are independent of one another, there will be no intersection of their circles on a Venn Diagram.
True
False
True
If the two events in a problem are independent, they cannot occur at the same time. That means their circle will not intersect and they will not have a shared middle section.
Example Question #1 : How To Find Range
On the last day of school,Adam asked each of his classmates how many days of school they missed for the entire school year. He created a stem-and-leaf plot with the information.
0 | 0 0 2 4 5 6 8
1 | 0 0 1 2
2 | 3
4 | 7
What is the range of the number of days missed by Adam's classmates?
To find the range of a set of data, simply subtract the smallest total from the largest total. The left side of a stem-and-leaf plot represents the ten's digit, and the right side represents the one's digit. The largest value here is 47. The smallest value is 0.
Example Question #1 : Data Analysis And Probability
Find the range in this set of numbers:
4520, 7325, 8732, 8321, 9031, 3117, 6960
First order the numbers from least to greatest:
Then find the difference of the greatest and the smallest number:
Answer: The range is 5914.
Example Question #1 : Data Analysis
Find the range in this set of numbers:
6059, 6609, 6906, 6509, 6905, 6960, 6950
First, order the numbers in the set from least to greatest:
Then, find the difference between the largest and the smallest number:
Answer: The range is 901.
Example Question #1 : Data Analysis
Find the range in this set of numbers:
640, 782, 411, 398, 299, 344
First, order the numbers from least to greatest:
Then, find the difference between the largest and smallest number:
Answer: The range is 483.
Example Question #1 : Data Analysis And Probability
Find the range in this set of numbers:
9881, 9889, 9818, 9981, 9891, 9918, 9989, 9889, 9198
First, order the numbers from least to greatest:
Then, find the difference of the largest and smallest number:
Answer: The range is 791.
Example Question #2 : Data Analysis
Find the range in this set of numbers:
3343, 4434, 4334, 3343, 4343, 3434, 3334
First, order the numbers from least to greatest:
Then, find the difference between the largest and the smallest number:
Answer: The range is 1100.
Example Question #1 : Data Analysis And Probability
Subtract the range from the mode in this set of numbers:
First, order the numbers from least to greatest:
Then, identify the mode (most recurring number): 6366
Then, identify the range (subtract the smallest number from the largest):
Finally, subtract the range from the mode:
Answer: 330
Example Question #1 : How To Find Range
Find the range for this set of numbers:
6363, 6336, 6366, 6633, 6333, 6363, 6663
First, order the numbers from least to greatest:
Then, find the difference of the largest and the smallest numbers:
Answer: The range is 330.
