Or a set of time series data, the following measures of forecast accuracy
were found using the naive method as the forecast for the next period.
MAE = 5.00
MSE = 25.40
MAPE = 34.93%
For the same time series data, the following measures of forecast accuracy were found using the average of all the historical data as the forecast for the next period.
MAE = 3.11
MSE = 11.21
MAPE = 22.43%
Which method, the naive method or using the average of all the historical data,
appears to provide the more accurate forecasts for the historical data? Explain
A. Using the naive method appears to provide more accurate forecasts, because
MAE, MSE, and MAPE using that method are all lower than MAE, MSE, and
MAPE using the average of all the historical data.
B. Using the average of all the historical data appears to provide more accurate
forecasts, because MAE, MSE, and MAPE using that method are all lower than
MAE, MSE, and MAPE using the naive method.
C. Using the average of all the historical data appears to provide more accurate
forecasts, because MAE, MSE, and MAPE using that method are all higher than
MAE, MSE, and MAPE using the naive method.
D. Using the naive method appears to provide more accurate forecasts, because
MAE, MSE, and MAPE using that method are all higher than MAE, MSE, and
MAPE using the average of all the historical data.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

no he doesnt because "-16' is negatiive

step-by-step explanation:

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
