A copper smelting process is supposed to reduce the arsenic content of the copper to less than 1000 ppm. Let μ denote the mean arsenic content for copper treated by this process, and assume that the standard deviation of arsenic content is σ = 140 ppm. The sample mean arsenic content X¯¯¯ of 95 copper specimens will be computed, and the null hypothesis H0: μ ≥ 1030 will be tested against the alternate H1: μ < 1030. A decision is made to reject H0 if X¯¯¯≤ 1010. Find the power of the test if the true mean content is 985 ppm. Round the answer to four decimal places.

The power is

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
