A marketing research company desires to know the mean consumption of meat per week among males over age 35. A sample of 3611 males over age 35 was drawn and the mean meat consumption was 2.5 pounds. Assume that the population standard deviation is known to be 1.4 pounds. Construct the 99% confidence interval for the mean consumption of meat among males over age 35. Round your answers to one decimal place.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

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
