Write an integer to represent the situation: The class gained seven points on their class average

7.666270253x10 raised to the 18th power

72 is the mode because it shows up the most number of times

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
