krok68 [10]

Answer:

a = 73.84, b = -23.64, c = 83.97, d = 21.73

Step-by-step explanation:

1880:

The predicted value is:

f(80) = 1.363\cdot (80) - 35.2

f(80) = 73.84

The residual value is:

\Delta f = 50.2 - 73.84

\Delta f = -23.64

1920:

The predicted value is:

f(120) = 7.8 \cdot 1.02^{120}

f(120) = 83.97

The residual value is:

\Delta f = 105.7 - 83.97

\Delta f = 21.73
