In a simple random sample of 52 electronic components produced by a certain method, the mean lifetime was 1,050 hours. assume that component lifetimes are normally distributed with population standard deviation 193 hours. what is the upper bound of the 95% confidence interval for the mean lifetime of the components?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

look at the picture i have filled out a table for it. hope this .
