(if 2 is a square)
6xy ( x2 - xy + y2)
= 6x3y - 6x2y2 - 6xy3 --------------the threes and twos on this line are squares and cubics. the six is just a whole number
The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
Answer:
women : men
5. : 4
x. : 2400
x = 3000
i) 3000 + 2400= 5400
ii) 3000
iii) 3000 - ( 2400+400) = 200
Answer:
x = 60
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary meaning
x + 2x = 180
Then you just solve the equation
