1. While FF was started 40 years ago, its common stock has been publicly traded for the past 25 years. 2. The returns on its equity are calculated as arithmetic returns. 3. The historical returns for FF for 2012 to 2016 are:

hello some details/parts of your question are missing attached below is the missing part

answer : A ) = 24.13%

              B ) =  0.1084, The preceding data series represents a SAMPLE        

              C ) =  0.4494

Explanation:

A) The average realized  return on FF stock can be calculated as

= 24% + 16.15% + 29% +39.9% + 12.35% / 5

= 24.13%

B) The preceding data series represents a SAMPLE  standard deviation BECAUSE RETURNS WERE MADE ONLY FOR FIVE YEARS

and the sample standard deviation is calculated as

 =   0.01175056

s = = 0.1084

C) coefficient of variation

coefficient of variation = standard deviation / mean

                                      = 0.1084 / 0.2413 = 0.4494

answer with step-by-step explanation:

a. wx is perpendicular to xy - true:

(since x is adjacent to x and y and all angles are 90 degrees in a square, therefore wx is perpendicular to xy)

b. ∠w is congruent to ∠x - true:

(all angles in a square are equal to each other)

c. ∠w is supplementary to ∠x - true:

(∠w and ∠x both are right angles which add up to 180 degrees so they are supplementary angles)

d. wxyz is a rhombus - true:

(a rhombus has all sides equal in length and so has a square so it is a rhombus)

e. wxyz is a trapezoid - false:

(a trapezoid has only one pair of parallel sides while a square has two pairs of parallel sides)

f. wx is parallel to yz - true:

(wx and yz are parallel to each other)
