Answer:
65.04<x<68.96
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = x ± z*s/√n
x is the mean = 67
z is the 95% z score = 1.96
s is the standard deviation = 8
n is the sample size = 64
Substitute;
CI = 67 ± 1.96*8/√64
CI = 67 ± 1.96*8/8
CI = 67 ± 1.96
CI = (67-1.96, 67+1.96)
CI = (65.04, 68.96)
Hence the confidence interval for the mean of the population is between 65.04<x<68.96
What is the area the sprinkler can water?
Area = π r²
r = 18 feet
r² = r * r = 324
A = 3.14 * 324
A = 1017.36
A = 1017 square feet
Answer:
The system has no solutions
Step-by-step explanation:
we have
-----> equation A
----> equation B
Isolate the variable y in the equation A
-----> equation A'
Isolate the variable y in equation B
------> equation B'
Compare the equations A' and B'
The lines have the same slope but different y-intercept
Are parallel lines
therefore
The system has no solutions
