Where is the lower quartile located in this box plot? a. 14 b. 15.5 c. 16.5 d. 17 e. 20

b. 15.5

the lower quartile will mostly be on the left end line of the box where 15.5 is.

hope this helps! ❤ from peachimin

B. 15.5

Step-by-step explanation:

We have been given a graph of box plot and we are asked to find the location of lower quartile from the box plot.

Since we know that lower quartile is also known a 1st quartile. It represents the median of the lower half of the data set. Lower Quartile is always represented by left end line of the box.  

Upon looking at our box plot we can see that left end of box is at 15.5, therefore, our lower quartile is located at 15.5 in the given box plot and option B is the correct choice.

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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