3x - 3 = 2x
Add 3 on both sides
3x - 3 + 3 = 2x + 3
3x = 2x + 3
Subtract 2x on both sides
3x - 2x = 2x + 3 - 2x
3x - 2x = 3
x = 3
So, your final answer is x = 3.
X = 8

Answer:
5/8
Step-by-step explanation:
The standard error of the estimate of average height in the city is 0.25.
Given average height 64 inches, sample mean and sample standard deviation of 4 inches.
We have to determine the standard error of the estimate of the average height in the city.
Standard error is the error which is predicted before research to happen in research. It is calculated by dividing the standard deviation of the sample by the square root of the sample size.
n=256
μ=mean
s = sample standard deviation
Standard error=s/![\sqrt{n}](https://tex.z-dn.net/?f=%5Csqrt%7Bn%7D)
=4/![\sqrt{256}](https://tex.z-dn.net/?f=%5Csqrt%7B256%7D)
=4/16
=0.25
Hence the standard error of the estimate of the average height is 0.25.
