we are given
Since, we have to solve this inequality
so, we will isolate x on anyone side
step-1:
Multiply both sides by 3/2
step-2:
Distribute negative sign
step-3:
Subtract both sides by 1/2
step-4:
Subtract both sides by (3/10)x
step-5:
Multiply by sides by -10/23
now, we can simplify it
now, we can write in interval notation as

Answer:
0.03
Explanation:
First, you subtract the upper bound of the confidence interval by the lower bound of the confidence interval. Then, you divide that number by 2 to get the margin or error.
In this case: (0.49 - 0.43)/2 = 0.03
Answer:
4 x 5 = 20
7 x 5 = 35
the cost per ticket is constant because the two numbers are both multiplied by five in order to get the main cost of the tickets
Step-by-step explanation:
A) multiplier = 1.13
30 x 1.13 = 33.9
B) multiplier = 0.85
250 x 0.8 = 200
C) multiplier = 0.72
825 x 0.72 = 594
