Answer: Yes

Step-by-step explanation: An arithmetic sequence is a sequence that has a common difference. The common difference is the number that is repeatedly added or subtracted to reach the next term in the sequence.

In this sequence, notice that we start with 15. Then, we subtract 2 to reach our next term which is 13. Next, we subtract 2 to get to our next term which is 11. In the same way, we subtract 2 from 11 to reach our next term, 9.

The dot dot dots just mean that this sequence goes on forever so to answer your question, this is indeed an arithmetic sequence.

Which missing side length makes the perimeter , p = 26 feet true?
Anastaziya [24]
If the width is 3 on each side, that is 3 + 3 = 6. 
26 - 6 = 20. 
There are two sides left: 20 divided by 2 = 10. 
10+10+3+3 = 26.
The length is 10.

Answer: 0.31

Step-by-step explanation:

Let A denotes the event of Tampa Bay Buccaneers will score a touchdown on their opening drive and B denote the event that their defense will have 3 or more sacks in the game.

Given : P(A)=0.14     P(B) = 0.31     P(A or B)=0.14

Formula : P(A and B)= P(A) + P(B) - P(A or B)

Now, the probability that they will both score a touchdown on the opening drive and have 3 or more sacks in the game will be :-

P(A and B)= 0.14 + 0.31 - 0.14=0.31

Hence, the required probability : 0.31
