Answer:
The distance from A to C along a direct route is either 48 miles or 60.71 miles depending on the interpretation of the question.
Step-by-step explanation:
The two possible interpretations of this question are presented in the attached image to this solution.
From the first interpretation, the three sides can just be related using pythagoras theorem.
AB² = AC² + BC²
AB = 50 miles
AC = ?
BC = 14 miles
50² = AC² + 14²
AC² = 50² - 14² = 2304
AC = 48 miles.
Using the second interpretation, we can relate the 3 sides using cosine rule.
AC² = AB² + BC² - (2)(AB)(BC) cos 135°
AB = 50 miles
AC = ?
BC = 14 miles
AC² = 50² + 14² - (2)(50)(14) cos 135°
AC² = 3685.95
AC = 60.71 miles
Hope this Helps!!!
Answer: (1.4964, 1.5126)
Step-by-step explanation:
We know that the confidence interval for population mean is given by :-
, where = population standard deviation.
n= sample size
= Sample mean
As per given , we have
σ = 0.01 inches
n= 10
Also, the critical value for 99% confidence interval = [From x-value table.]
[Significance level =1-0.99=0.01 and is 2.576.]
Then, the 99% two-sided confidence interval on the mean hole diameter will be :-
Hence, the required confidence interval = (1.4964, 1.5126)
