Answer:
z = -0.577
Step-by-step explanation:
sample mean = ( 24.3 + 24.9 + 24.8 ) / 3 = 24.667
n = 3
σ = 1.0
Test statistic:
z = ( 24.667 - 25 ) / ( 1/SQRT(3) )
z = -0.577
Answer:
-25x⁵y⁵
Step-by-step explanation:
Coefficients include (-5)(5) = -25
x-factors include (x^3)(x^2) = x^5
y-factors include (y^2)(y^3) = y^5
Then the product is ...
... -25x^5·y^5
