Which point represents the outlier? OA. (2,3) O B. (4, 5) O C. (3, 13) OD (8,9)

Picture relating to the required graph is attached below

C. (3, 13)

Step-by-step explanation:

According to the inspected scatterplot, we could actually observe a possible data trend which is where the majority of the samples are clustered. In a graphical representation of data, data points which deviates away from the trend of the majority of the points are considered as outliers. In the scenario above, the point (3, 13) seems too far off from the actual trend line, thus showing a greater y value than the pattern actually predicts.

y=x+9

?

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)

(a + b) (a^2 - a b + b^2)
