For this case we have that the expression in its exact form is the same, that is:
If it is expressed in decimal form we have:
If we want equivalent expressions, we must first mention the following property of powers and roots:
Then, we can rewrite the expression as:
Answer:
Yes, I would say the answer is Small Sample.
In order to make an accurate study, you would want to have more than 3 samples. I would say at least 500-1000 depending on what the subject is about and where it takes place.
Let me know if this helps :) Have a nice day!
Answer:
y=2x-4
Step-by-step explanation: this looks alot like an equation for slope is it?
Answer is I’m so freakin grateful for my ex
Answer: (-2,1)
Step-by-step explanation:
y=x+3
y=2x+5 substitute the y value in the first equation into the second equation
x+3 = 2x+5 now solve for x
-3 -3
x = 2x +2 subtract 2x from both sides
-2x -2x
-1x = 2 Divide both sides by -1
x= -2
The value of x is -2 to plot it into one of the equations to solve for y.
y= -2 + 3
y = 1
(-2,1)
