1) If the population mean m is 80, the population standard
deviation s = 14, and the sample size n= 49, what are the
values of m and s? (IN CASE YOU CAN'T READ THE
NOTAION OR IF THE BAR DOESN'T PRINT OUT OR
SHOW UP ON YOUR SCREEN, I'M ASKING FOR THE
AVERAGE AND STANDARD DEVIATION NOT FOR
X, BUT FOR THE SAMPLE AVERAGE. (SEE SECTION
8.1). (6 POINTS)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

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
