Answer to Problem 8PPS
The equation in slope-intercept form is
Explanation of Solution
Given: The given points are
Calculation: The slope for the line of fit using the points
Now, the equation for the line of fit using the slope
The prediction for the milk production in the year 2015.
Answer to Problem 8PPS
The estimated milk production in the year 2015 is 16.875 gallons.
Explanation of Solution
Given: The given points are
Calculation: The prediction for the milk production in the year 2015 can be evaluated by plugging
The year in which the consumption of milk will be 10 gallons.
Answer to Problem 8PPS
The equation for the line of fit is
Explanation of Solution
Given: The given points are
Calculation: For, the consumption of milk to be 10 gallons, plugging
Hence, adding 33 to the base year 2000, the year we get is 2033. Therefore, in the year 2033 the consumption of milk will be 10 gallons.
Can the equation of line of fit give the reasonable estimate for any year to find the consumption of milk? Explain.
Answer to Problem 8PPS
Yes, the equation for the line of fitgives reasonable estimate for any year to find the consumption of milk.
Explanation of Solution
Given: The given points are
Calculation: Yes,the equation for the line of fit gives reasonable estimate for any year to find the consumption of milk because the equation for the line of fit represents the close approximation trend between the given two variables.
