S is the set of real numbers that are less than 15
A) 0 < s < 15
B) {s/s < 15}
C) {s/s <_ 15}**
D) {s/s <_ 15}
I think it's c, but I'm not sure, I'm sorry, I'm really bad at this.. Any help would be greatly appreciated!!
so the answer i got after i took the test was B) {s l s < 15 }
Hope this helps!! :)
Working with Sets Practice
1. {1, 2, 3, 4, 6, 12}
2.{s|s<15}
3.{r|r>11}
4.{d|d is less than or equal to -7}
5.{p|p is greater than or equal to 1}
6.{ };{1}
7. { };{-2};{2};{-2,2}
8. {dog}, {cat}, {fish}, {dog,cat},{dog,fish},{cat,fish},{dog,cat,fish}
9. {1,3,5,7}
10. {...-4,-2,2,4...}
10 is {…-4, -2,0,2,4}
And 3 is {r | r <11}
C is the wrong choice
in C, you have numbers less than or equal to 15, your question does not say that.
No problem at all! I'm here to help you understand. Let's go through each option and see which one correctly describes the set S of real numbers that are less than 15.
A) 0 < s < 15
This option states that s is greater than 0 and less than 15. However, it does not include the case where s can be equal to 0. So this option doesn't cover all the real numbers that are less than 15.
B) {s/s < 15}
This option represents a set containing s where s is less than 15. It correctly represents the condition for s being less than 15. However, the representation using "{ }" suggests a set of individual elements, which does not match the intention of describing a range of real numbers.
C) {s/s ≤ 15} (with the <= sign)
This option represents a set of s where s is less than or equal to 15. The use of the less than or equal to (≤) sign accounts for all the real numbers that are less than 15, including the number 15 itself. So this option is correct.
D) {s/s ≤ 15} (with the <= sign)
This option is identical to option C, so it is not a different choice.
Therefore, the correct option is C) {s/s ≤ 15}.
I hope this helps clarify the answer for you! Let me know if you have any further questions.
