Answer:
a. MSE = 64.8
b. Forecast for month 8 is 14.
Step-by-step explanation:
where
Using the most recent value as the forecast for the next period, we have forecasts for the months as;
(1,-) , (2,25) , (3,13) , (4,21) , (5,13) , (6,20) , (7,22)
= (-, -12, 8, -8, 7, 2, -8, -)
= (-, 144, 64, 64, 49, 4, 64, -)
Therefore, MSE = 64.8 (1 decimal place).
The Forecast for month 8 is 14 since we are using the most recent value as the forecast for the next period.
Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,
3x = 2x + 3
3x - 2x = 3
x = 3
Similarly,
y =
y = 6
