we are given
f(x)=[x=1]
where bracket means ceiling functions
we know that
Ceiling function returns the least value of the integer that is greater than or equal to the specified number
so, we can check each options
option-A:

At x=-4:
f(x)=[-4-1] =-5
For x<-3:
Let's assume
x=-3.1
f(x)=[-3.1-1] =[-4.1]=-5
so, this interval is TRUE
option-B:

At x=-2:
f(x)=[-2-1] =-3
For x<-1:
Let's assume
x=-1.1
f(x)=[-1.1-1] =[-2.1]=-3
so, this is FALSE
Try A? I’m not 100% sure but I got A
Answer:
letter a is the correct answer
Answer:
A. 40 combinations
we have 8 x 5 = 40
Step-by-step explanation:
Would be 60 as 3 letter words with 5 letters.
The logic is that all letters are being used to their maximum and with numbers 3 within 5 or 5 within 5 the maximum that cna be used is 12 rotation for 3 per letter or 8 rotaion for 5. Then we have 5 rotations = 60 for 3 and 40 for 5. Another logic is the many combinations can you make from the numbers 1 2 3 4 5 not multiplying?
The rearrangement of 5 figure numbers will be 5x4x3x2x1 which is 120 combinations, when you don't repeat a number.
We see that 4+3 +2+1 = 10 and shows less than 5 number combinations at 120, and then we have 5
5:10 ratio = 5/15 = 1/3
This = 1/3 of 120 =40
Then we find answer is 40 as compact 5 letter words from the word tight.
If you are looking for 185% as a fraction, you need to put your percentage over 100.
185% converted into a fraction is 185/100.
If you are looking for 1.85%, it is 1.85/100
I hope this helps!
