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:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
