Answer:
Slope:
Equation:
Step-by-step explanation:
The line of the best fit passes through the points (0,8) and (4,6).
If the line passes through the points and
then the slope of the line is
Hence, the slope of the line of the best fit is
The equation of the line is
where m is the slope and b is y-intercept, so the equation of the line of the best fit is
The vertex form:
The axis of symetry is x = h.
We have
Substitute:
The standard deviation<u> </u><u>INCREASES</u>
Step-by-step explanation:
Standard deviation is used to show how the points of the data deviate from the mean. The formulae for deriving standard deviation is attached. As seen from the formulae, the greater the variance of the data from the mean, the higher the Standard Deviation.
The mean of the given data points is $103.4. $450 is way off from this mean meaning that there is a large variance in this data point.
