Answer:
87-31 will equal n
Step-by-step explanation:
2y=-x+9
6y=3(-x+9)
3x-3(-x+9)=-15
3x-(-3x+27)=-15
3x+3x-27=-15
6x=-15+27
6x=12
x=2
2y=-2+9
2y=7
y=7/2
Answer is (2 ; 7/2)
Answer:
Step-by-step explanation:
From the given information;
The null and alternative hypothesis is:
sample mean x = -2
population mean = 0
SD = 6
sample size n = 25
Using t-test statistics:
t = -1.667
P-value = P(t ≤ -1.667) + P(t ≥ 1.667)
P-value = 0.1086
Since P-value is greater than , we fail to reject .
If you simply solve the equation for w, rather than "guess and check" using the values in the "replacement set," you find ...
... 6w +6 = 60 . . . . simplify the equation
... 6w = 54 . . . . . . . subtract 6
... w = 9 . . . . . . . . . divide by 6
The appropriate choice is ...
