Answer:
1 < x < 4 . . . . {x | x < 4 <u>and</u> x > 1}
Step-by-step explanation:
We want to write the answer as a compound inequality, if possible. As it is written, we can solve each separately.
x + 1 < 5
x < 4 . . . . . . . subtract 1
__
x -4 > -3
x > 1 . . . . . . . add 4
So, the solution is ...
(x < 4) ∩ (x > 1) . . . . . . the intersection of the two solutions
As a compound inequality, this is written ...
1 < x < 4

Answer:
A. 16/36
B. 28/36
C. 24/36
D. 8/36
Step-by-step explanation:
Above I have the probability chart. Their are 36 students so that’s the ’out of’ thing I used, for instance, Answer A: the probability of you meeting a student who only eats lunch is: 16 out of 36 (16 students who eat lunch, while 36 altogether.)
I wish you luck on this homework!!!!
Since the discriminant is positive, this means we have two distinct real solutions.
If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
