Question statement:

The box plots show the target heart rates of men 20-40 years old and men 50-70 years old.

Which statement is best supported by the information in the box plots?

A)

The range of the data for men 20-40 years old is less than the range of the

data for men 50-70 years old.

B)

The median of the data for men 20-40 years old is less than the median of

the data for men 50-70 years old.

o

The minimum target heart rate for men 20-40 years old is less than the

minimum target heart rate for men 50-70 years old.

D)

The interquartile range of the data for men 20-40 years old is greater than

the interquartile range of the data for men 50-70 years old.

D

Step-by-step explanation:

please find the box plots in the file attached below.

looking at the box plots we can say that the answers is D due to following reasons:

Option A is incorrect:

The range of the data for men 20-40 years old is not less than the range of data for men 50-70 years old because  for men 20-40 years old range is 80 and for men 50-70 years old range is 70.

Option B is incorrect:

The median of the data for men 20-40 years old is not less than the range of data for men 50-70 years old because  for men 20-40 years old median is 130 and for men 50-70 years old median is 110.

Option C is incorrect:

The minimum target heart rate for men 20-40 years old is not less than the minimum target heart rate for men 50-70 years old because  for men 20-40 years old the minimum target heart rate is 90 and for men 50-70 years old the minimum target heart rate is 75.

Option D is correct:

The interquartile range of the data for men 20-40 years old is greater than the interquartile range of data for men 50-70 years old because  for men 20-40 years old interquarile range is   and for men 50-70 years old interquartile range is .

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
