Answer:
(3,3)
Step-by-step explanation:
2) solve for 'x': 2/3x + 1 = 4/3x - 1
1 = 2/3x - 1
2x = 6
x = 3
now solve for 'y':
y = 2/3(3) + 1
y = 2 + 1
y = 3
20 because for all regular polygons their exterior angles add up to 360, so 360\18 =20
Answer:
24.4
Step-by-step explanation:
15.86 /0.65 = 24.4
Answer:
(d) μ and σ²/n
Step-by-step explanation:
In a sampling distribution of sample means, the mean is equal to the population mean, which is μ.
The standard deviation of the sampling distribution of sample means is given by
σ/√n.
The variance of a distribution is the square of the standard deviation; this means the variance of the sampling distribution of sample means would be
(σ/√n)² = σ²/(√n)² = σ²/n
