Question 1: testing to see if there is evidence that the proportion of us citizens who can name the capital city of canada is greater than 0.75. state the null and alternative hypotheses. also, state the direction of the test using the following possible sample results: • sample a: 31 successes out of 40 • sample b: 34 successes out of 40 • sample c: 27 successes out of 40 • sample d: 38 successes out of 40 state which of the possible sample results provides the most evidence against the null. briefly explain state which (if any) of the possible results provide no evidence for the alternative. briefly explain

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

the correct answers i think are b. and d.

give me brainliest if it is correct!
