Answer:
+ closed
- closed
* closed
÷ not closed
Step-by-step explanation:
When you add integers, you will always get an integer so it is closed under addition
When you subtract integers, you will always get an integer so it is closed under subtraction
When you multiply integers, you will always get an integer so it is closed under multiplication
When you divide integers, you will not always get an integer so it is not closed under division
1/5 = .2 which is not an integer
In scientific notation, you want a number between 1 and 10; so the answer is <u>9.57 x 10</u> (to the understood first power).
I think 40/3 is the answer you’re looking for.
Hey there! I'm happy to help!
Inductive reasoning is looking at a trend and making a guess or non-specific generalization based off of it while deductive reasoning is looking at a fact or piece of data and figuring out another specific fact or piece of data based off of it.
The area of a parallelogram is always the base multiplied by the height. Our base is 3 and our height is 5. If you multiply 3 and 5, you get 15. This is deductive reasoning because we use start with information and use given steps to find an answer. Inductive reasoning is coming up with more of a guess looking at trends that you cannot confirm is 100% correct.
Have a wonderful day! :D
