92/2 gives you how many they sold in one month, which is 46. now add that to 92 to get how many to buy in 3 months.
92+46=138.
they need a minimum of 138 jeans

Answer:
AREA OF SHADED REGION=AREA OF LARGE PARALLELOGRAM-AREA OF SMALL PARALLELOGRAM
=8*12-(6*4)
=96-24
=72unit^2
Answer:
Step-by-step explanation:
we are given a derivative
and said to figure out the first derivative
to do so
recall chain rule:
so we get
rewrite the derivative using the chain rule:
use square root derivative rule to simplify:
now we need to again use chain rule composite function derivative to simplify
where we'll take a new function n so we won't mess up two g's and we'll take 2x as n
use composite function derivative to simplify:
use derivative formula to simplify derivatives:
substitute the value of n:
substitute the value of g:
now we need our trigonometric skills to simplify
rewrite cot and csc:
simplify multiplication:
simplify multiplication:
Answer:
may have different df values but they all have the same denominator
Step-by-step explanation:
In a two-factor analysis of variance, the F-ratios for factor A, factor B, and the AxB interaction _____. may have different df values but they all have the same denominator
In two--factor analysis of variance, the estimates of the variance can be obtained by partitioning the total sum of squares into three components corresponding to the three possible sources of variation , viz; Between Rows, Between Columns, and Within Samples or error.
As the number of rows and columns may differ the degrees of freedom differ with them.
In other words
Total df= Rows df + Columns df + Error df
Since the variance is identically the same for each row of the c values and variance is the same for each observation in the jth column of r values the sum of squares becomes an identity.
Therefore it may have different df values but they all have the same denominator.
