Answer:
Step-by-step explanation:
Alright, lets get started.
Using sin Law,
Plugging the value of a, b and angle A
taking sin inverse on both sides
The may be another value of B that will called B' =
We will not consider this B' value because the um of angle B' and A will exceeds 180 degree ()
Thats why only one triangle is possible. : Answer
Hope it will help :)
Answer:
We are 98% confident interval for the mean caffeine content for cups dispensed by the machine between 107.66 and 112.34 mg .
Step-by-step explanation:
Given -
The sample size is large then we can use central limit theorem
n = 50 ,
Standard deviation = 7.1
Mean = 110
1 - confidence interval = 1 - .98 = .02
= 2.33
98% confidence interval for the mean caffeine content for cups dispensed by the machine =
=
=
First we take + sign
= 112.34
now we take - sign
= 107.66
We are 98% confident interval for the mean caffeine content for cups dispensed by the machine between 107.66 and 112.34 .
