Im Not That sure But I Belive That If Denominators Are The Same Keep It And Just Do The Math In The Numerator's . ( For Adding ) But Multiplying You Do Both and If The Numerator Is The Bigger Than The Denominator Your Going To Have To Do Extra Math Like A Common Denominator ( I Belive ) .

The chef at a school cafeteria asked 100 male and 100 female students
Fantom [35]

Answer:

A

Step-by-step explanation:

The best way to do is this by cancellation.  Cancel out the answers that are incorrect.

D is incorrect.  There are 100 male students and 100 female students.  This table shows that there 94 male students and 106 female students.

C and B are both incorrect because they say that there are 42 male students that dislike peas.  Really, there are 42 male students that like peas.

This leaves you with letter A.  The table matches the data given, so this is the answer.

Write the set in roster form if M is the set of integers that are greater than -1 and less than 4
alekssr [168]
When they say "roster form" they basically mean "list out every element individually". Think of a roster on a baseball team. The roster lists all the players by name.

So 
M = set of integers that are greater than -1 and less than 4
M = {0, 1, 2, 3}

The answer is {0, 1, 2, 3} which lists out all the numbers that fit the criteria mentioned above. Note how -1 is not part of the set. Neither is 4. 

Note: if there are a lot of numbers to list out, then often you'll use three dots or ellipses to shorten things down. For example, writing {0, 1, 2, 3, .., 99, 100} indicates that we're listing all the whole numbers from 0 to 100 including both endpoints.
