The heights of adult men in america are normally distributed, with a mean of 69.8 inches and a standard deviation of 2.61 inches. the heights of adult women in america are also normally distributed, but with a mean of 64.6 inches and a standard deviation of 2.51 inches. a) if a man is 6 feet 3 inches tall, what is his z-score (to two decimal places)

1.99

Step-by-step explanation:

We have been given the heights of adult men in America are normally distributed, with a mean of 69.8 inches and a standard deviation of 2.61 inches. We are asked to find the z-score of height of man with 6 feet 3 inches.

We will use z-score formula to solve our given problem.

, where,

z = z-score,

x = Sample score,

= Mean,

= Standard deviation,

6 feet 3 inches = 72+3 inches = 75 inches

Therefore, the z-score for the man with height of 6 feet 3 inches is 1.99.

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
