Answer:
6(3-2)
Step-by-step explanation:
Find the GCF of both numbers. The GCF is 6. Write it as 6( - )
Then, divide both numbers by 6. 18 divided by 6 is 3 and 12 divided by 6 is 2. Fill in the blanks with 3 and 2. A=6(3-2)
Answer:
The general term for the sequence can be given by the following formula:

Step-by-step explanation:
If the sequence you typed starts with first term 11 and continues with terms 13, 15, 17, 19, We understand that the sequence is formed by adding 2 units to the previous term. So we are in the case of an arithmetic sequence with constant difference (d) = 2, and with first term 11.
Therefore, the nth term of this arithmetic sequence can be expressed by using the general form for an arithmetic sequence as:

Numbers aren't necessary in a statistical question. For example if a question stated "There are twice the amount of blue marbles than red marbles in a bag, whats the probability you will pick a red marble?" No numbers are involved in the question but you can still find statistics.
Yes it should, 0 is still a number even though it’s value is nothing. You can’t get to -1 without 0.
