Answer:
x=10
Step-by-step explanation:
Use the Pythagorean Theorem, which is a^2+b^2=c^2
The formula would lead to:
6^2+8^2=x^2
36+64=x^2
100=x^2
10=x
B is the right answer
f(x) = x-3
y= x-3
x= y-3
x+3 =y
f^-1(x) = x+3
Answer:
with a .95 probability, the sample mean will provide a margin of error 0.196
Step-by-step explanation:
margin of error (ME) from the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic in the .95 confidence level (1.96)
- s is the population standard deviation (1 min.)
- N is the sample size (100)
ME=
=0.196
95% confidence interval for check-out time would be 3 ±0.196 min
