Answer:
Step-by-step explanation:
To find the GCF we factor all the given terms and then find the Greatest Common Factor from both ,
So , The given two terms can be given by

Here common numbers that are in both are
2.7.c.c.d
so GCF= 
The choices
A, D, and E, are geometric series
Answer: The answer is ¨B¨
Step-by-step explanation:
Cannot reduce, it is already in simplest form. You can convert it to a decimal though, 0.671875
Answer:

Step-by-step explanation:
We are given a joint probability table.
There are four different graders in a school
1. Grade Ninth
2. Grade Tenth
3. Grade Eleventh
4. Grade Twelfth
Field trip refers to the students who will attending the amusement park field trip.
No field trip refers to the students who will not be attending the amusement park field trip.
We want to find out the probability that the selected student is an eleventh grader given that the student is going on a field trip.

Where P(eleventh and FT) is the probability of students who are in eleventh grade and will be going to field trip

Where P(FT) is the probability of students who will be going to field trip

So the required probability is
