500 in 2:3 is saying that there are five different parts (2 + 3)
This means that 500 needs to be split into five, which is 100.
After that all you need to do is put 2 'sections' on one side and 3 on the other.
For example, 2 : 3 = 2( x 100) : 3( x 100)
= 200 : 300
To find the standard error, divide the standard deviation by the square root of the sample size
standard deviation = 7.5
sample size = 25......sqrt 25 = 5
standard error = 7.5 / 5 = 1.5 <==
Eduardo is packing 12 pairs of mismatched socks for his trip.
Answer: 
Step-by-step explanation:
There is a double root at x=5 and a single root at x=-2, so we know f(x) is of the form 
for some constant a.
To find a, we can substitute the coordinates of the y-intercept, (0, -50).
So,
