Answer:
13≥x U x≥65
Step-by-step explanation:
For a customer to have the reduced movie price tickets, they have to be 13 or younger, or 65 or older so I made the inequality, (X is less than or equal to 13) Union (X is greater than or equal to 65)
Area of each triangle
(1/2)(7)(13) = 45.5
Both triangles = 91cm^2
Area of rectangle = 4 * 13 = 52
52cm^2 + 91cm^2 = 143cm^2
The area of the parallelogram is 143cm^2
Answer:
1341.2<x<1458.8
Step-by-step explanation:
Given
sample size n = 64
standard deviation = 240
average mean = 1400
z score at 95% CI = 1.96
Required
confidence interval
Confidence interval = xbar ± (z*s/√n)
CI = 1400 ± (1.96*240/√64)
CI = 1400 ± (1.96*240/8)
CI = 1400 ± (1.96*30)
CI = 1400 ± 58.8
CI = (1400-58.8, 1400+58.8)
CI = (1341.2, 1458.8)
Hence the confidence interval for the population is 1341.2<x<1458.8
