we have the inequality
step 1
Find out the first solution (positive case)
The first solution is all real numbers less than or equal to 1.20
Interval (-infinite,1.20]
step 2
Find out the second solution (negative case)
Multiply by -1 both sides
The second solution is all real numbers greater than or equal to -2.8
the interval [-2.8, infinite)
step 3
Find out the solution to the given inequality
The solution is
[-2.8, infinite) ∩ (-infinite,1.20]=[-2.8,1.20]
the solution is the interval [-2.8,1.20]
see the attached figure to better understand the problem
2 or 3 caps = 13
6 or 7 caps = 6
13 - 6 = 7
Here is the answer for math problem
Step-by-step explanation:
A voluntary response sample is defined as a type of sample made up of self-chosen participants. These participants volunteer to take part in different research studies to share their opinions on topics that interest them. A voluntary response sample is made up of persons who volunteer to take research surveys.
t = number of tickets
15t ≥ 1500
so....
step 1. 15t ≥ 1500 --> divide both sides by 15 --> 15t/15 ≥ 1500/15
step 2. t ≥ 100
So 100 at the least, ticket should be sold to reach atleast $1500.
I hope this helps. :)
