Answer:
Step-by-step explanation:
<u>The standard form is:</u>
<u>Convert the given into standard form:</u>
Answer:
x = 5
Step-by-step explanation:
vertical angles are equal so we can write this equation:
2x-4 = x+1
x - 4 = 1
x = 5
Answer:
undefined
The problem:
Find the slope for the line going through (3,4) and (3,-4).
Step-by-step explanation:
Line up points vertically and subtract.
Then put 2nd difference over 1st.
( 3 , 4)
-(3 , -4)
------------
0 8
So the slope would have been 8/0 but this is undefined.
So the slope is undefined.
Also notice the x's are the same and the y's are difference so this is a vertical line. There is only rise in a vertical line and no run. Recall, slope is rise/run. You cannot divide by 0 so this is why we say the slope is undefined when the x's are always the same no matter the y.
Answer: Standard error.
Step-by-step explanation:
If the population is normally distributed , then the standard deviation of a sampling distribution of the sample mean ![[tex]\overline{x}](https://tex.z-dn.net/?f=%5Btex%5D%5Coverline%7Bx%7D)
[/tex] is known as standard error which depends on population standard deviation 
and the sample size (n).
It measure the variability in the sample statistics that happens by chance.
Thus, the standard deviation of a sampling distribution is called the <u>standard error</u>.
