Answer:
the covariance between the revenue and cost is 1,513. What is the variance of the profit (X-Y) of the company is 303468
Step-by-step explanation:
Given that;
E(x) = 6263
SD(x) = 440
F(y) = 4872
SD(y) = 336
COVI (x, y) = 1513
Variance x = [ SD(x) ]²
Variance x = [440]² = 193600
Variance y = [ SD(y) ]²
Variance y = [336]² = 112896
Now to get variance of the profit (X-Y) of the company we say;
variance ( x-y ) = variance x + variance y - 2covi(x.y)
we substitute
variance ( x-y ) = 193600 + 112896 - ( 2 × 1513 )
variance ( x-y ) = 306496 - 3026
variance ( x-y ) = 303468
therefore the covariance between the revenue and cost is 1,513. What is the variance of the profit (X-Y) of the company is 303468
Answer:
Step-by-step explanation:
< 3 and <6 are <u>same side interior angles </u>and
they are <u>supplementary angles</u> (they add up to 180°)
m<3 = 41°
m<6 = 180-41= 139°
<6 and <8 are <u>vertical angles</u> and <u>vertical angles are congruent </u>
(they have equal measures)
m<6 = 139°
m<8 = 139°
Answer:
A) Linear Expression
Step-by-step explanation:
Answer:
n = 36
Step-by-step explanation:
First, isolate the variable. Then, use the opposite operations to manipulate the inequality, whatever you do to one side you must to do the other, solve the right side to find your variable.
n - 22 + 22 < 14 + 22
n = 36
Answer:
z = -10
Step-by-step explanation:
5/10 = 1/2
1/2 of 10 = 5
