The parallel histograms below display the heights of men in each of two countries. Men's Heights by Country
Countries
50 55 60 65 70 75 80 85 90
Height in Inches
Which of the following statements is true?
A. The IQR for the distribution of men's heights is larger for country A.
B. The range for the distribution of men's heights is larger in country A.
C. The standard deviation for the distribution of men's heights is smaller in country B.
D. Men's heights in country B has a larger variation than men's heights in country A.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

tip $2.90

total $17.40

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
