Ascientist has a data set consisting of the temperature at which a chemical solution begins to evaporate. there are 500 measurements in the data set. he plans to estimate the standard error for the mean temperature by drawing a random sample from the data set consisting of 64 measurements. what formula would produce an estimate for the standard error of the sample?

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

using pemdas, (order of operations) you'll see the answer is 24.
