The FBI compiled a data table of murders in each state in 2016. The number of murders in 2016 can be modelled by a normal distribution with a mean of 233.67 and standard deviation of 210.23.

Test, using a 10% significance level whether the number of murders in 2016 come from the same distribution.

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

there is no question content here, but you for the free points! : d

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)

you,

mrb

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