Answer:

(a) MAE = 5.20

(b) MSE = 10

(c) MAPE = 38.60%

(d) Forecast for week 7 = 14

Step-by-step explanation:

Note: See the attached excel for the calculations of the Error, Error^2, and Error %.

(a) mean absolute error

MAE = Total of absolute value of error / Number of observations considered = |Error| / 5 = 26 / 5 = 5.20

(b) mean squared error

MSE = Total of Error^2 / Number of observations considered = Error^2 / 5 = 150 / 5 = 10

(c) mean absolute percentage error (Round your answer to two decimal places.)

MAPE = Total of Error % / Number of observations considered = Error % / 5 = 193.02 / 5 = 38.60%

(d) What is the forecast for week 7?

Since the forecast is based on the naive method (most recent value), the forecast for week 7 is value for week 6. Therefore, we have:

Forecast for week 7 = 14

melomori [17]

Answer:

Chantal and Trisha will have both traveled 105 miles in 20 minutes.

Step-by-step explanation:

$y$ is distance in miles, $x$ is time in hours.

The two equations are:

$y = \frac{20}{x} + 45$

$y = \frac{35}{x}$

Set them equal to each other and solve for x:

$\frac{35}{x} = \frac{20}{x} + 45$

$\frac{35}{x} - \frac{20}{x} = 45$

$\frac{35-20}{x} = 45$

$\frac{15}{x} = 45$

$x = \frac{15}{45} = \frac{1}{3} hours = 20 minutes$

Plug that back into the equations to confirm this $x$ gives the same $y$ :

$y = \frac{20}{1/3} + 45 = 105 miles$

$y = \frac{35}{1/3} = 105 miles$

first you find 60% of 357.50 which is $214.50. Next you would add $357.50+214.50=572

so the awnser is
