Intercept ⇒ when f(x) = 0
f(x) = 3x² - 12x - 1
3x² - 12x - 1 = 0
Answer: The two x-intercepts are (4.08, 0) and (-0.08, 0)
First, we calculate for the variance by dividing the given sum of the squared deviations by the number of data.
variance = (316) / 9 = 316/9
Then, get the square root of the answer to calculate for the standard deviation.
sd = sqrt (316/9) = 5.93
Thus, the standard deviation is approximately 5.93.
Okay.
620 would be rounded estimate to 600
