Example Question #361 : Numbers And Operations
Which of the following is true about the set below?
None of these
The numbers are all divisble by 4
The numbers are all multiples of 4
The numbers are all odd
The numbers are all prime
The numbers are all odd
The numbers in the set are all odd, meaning that they are not divisble by 2.
While the numbers in the set increase by 4 sequentially, they are not divisible by 4, and therefore are not multiples of 4.
Thus, the best answer is that they are all odd.
Additionally, the numbers are not prime because 9 and 21 are both divisible by 3.
Example Question #362 : Numbers And Operations
Jill is getting ready to go to school. She wakes up an hour before class starts and it takes her 15 minutes to walk to school. If class starts at 8:00, which of the following best describes when she must leave home to be at class on time?
She must leave in 45 minutes in order to leave at 7:45.
She must leave in 45 minutes in order to leave at 7:25.
She must leave in 40 minutes in order to leave at 7:45.
She must leave in 35 minutes in order to leave at 7:45.
She must leave in 45 minutes in order to leave at 7:45.
Given that Jill's class starts at 8:00 and that it takes her 15 minutes to walk there, she must leave at 7:45. Since she woke up an hour before class starts, at 7 am, this means that she must leave in 45 minutes. Therefore, the correct answer is:
She must leave in 45 minutes in order to leave at 7:45.

Example Question #16 : How To Add
Lisa has been tutoring students every day for the past six days. The first three days, she tutored 5 students each day. The last three days she tutored 3 students each day. On average, how many students did she tutor each day?
The average consists of the sum of the number of students tutored for the 6 days, divided by 6. Thus, the average would be calculated with this equation:
This is equal to
