A distributor of personal computers has five locations in the city. The sales in units for the first quarter of the year were as follows: Location Observed Sales (units) North Side 70 Pleasant Township 75 Southwyck 70 I-90 50 Venice Avenue 35 What is the p-value?

The P-Value is 0.009999

Step-by-step explanation:

we have 5 categories

df=5-1=4

With alpha = 1%, the critical Chi-square value is 13.277

The P-value is define as the shows the degree of inconsistency of our data set with hypothesis.

using a significant  level of 0.01,

The P-Value is 0.009999. The result is significant at p <0.01

answer: the first graph

step-by-step explanation:

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,
