Why did you post this then?
The problem is actually already factored for you. They are asking you to just set the equation to zero. Find the zeros.
Step-by-step explanation:
Given points (-1 , -2) and (3 ,10)
First calculating slope
Slope(m) = (y2 -y1) / (x2 - x1)
= ( 10+ 2)/ ( 3 + 1)
= 12 / 4
= 3
Now The equation of line is
y - y1 = m ( x - x1)
y +2 = 3 ( x +1)
y+2 = 3x + 3
y = 3x + 3 -2
y = 3x + 1
A. -5 x 3. This is because a negative times a positive equals a negative, aka the LOSS of 15 yards.
Answer: $5656.85
Step-by-step explanation:
The standard error of the mean measures the dispersion of sample means about the population mean .
It is also known as the standard deviation of its sampling distribution.
Formula :
, where
= population standard deviation.
n= sample size.
As per given , we have
sample size : n= 50
Then, the standard error of the mean will be :-

Hence, the standard error of the mean= $5656.85
