Answer:

MAPE = 2.33%

Step-by-step explanation:

The mean absolute percentage error (MAPE) can be determined by:

MAPE = \frac{100}{n} ∑|\frac{(Actual - Forecast)}{Actual} |

Given that:

                periods are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

              forecast are 25, 32, 42, 53, 64, 70, 81, 88, 95, 102

                  actual are 26, 31, 45, 50, 70, 72, 78, 90, 100, 110

Thus, n = 10 and;

∑|\frac{(Actual - Forecast)}{Actual} | = |\frac{(26 - 25)}{26} + \frac{(31 - 32)}{31} + \frac{(45 - 42)}{45} + \frac{(50 - 53)}{50} + \frac{(70 - 64)}{70} + \frac{(72 - 70)}{72} + \frac{(78-81)}{78} + \frac{(90-88)}{90} + \frac{(100-95)}{100} + \frac{(110-102)}{110}|

       = |0.0385 + (-0.0323) + 0.0667 + (-0.06) + 0.0857 + 0.0278 + (-0.0385) + 0.0222 + 0.05 + 0.07273|

      = 0.23283

Therefore;

MAPE = \frac{100}{10} x 0.23283

          = 10 x 0.23283

          = 2.3283%

          = 2.33%

The mean absolute percentage error = 2.33%

DanielleElmas [232]

Answer:

48 and 32 6 hours clearing tables and 2 hours tutoring

Step-by-step explanation:

we can rewrite this as a fraction. we will use 1/10s because 80 can be divided by 8 which is in the problem. we then have to find out what two numbers add up to 8 but one is 3 times the other. 6 and 2 fit into this problem so we plug it into the equation and we write it as this 6x+4x=80 where x is 8. we get 48 and 32.
