Write a quadratic variation equation if g(x) varies directly with x2, and g(x) = 108 when x = 6.
dlinn [17]
G(x) = k * x^2

108 = k * 6^2
108 = k * 36
Divide both sides by 36
3 = k

g(x) = 3x^2

mihalych1998 [28]

45000 \: m \times  \frac{1 \: km}{1000 \: m}

45 km in the 2nd hour

7500000 \: cm \times  \frac{1 \: m}{100 \: cm}  \times  \frac{1 \: km}{1000 \: m }

75 km in the 3rd hour

\frac{(75 - 30)}{(3 - 1)}

22.5 km/h

Answer:

301.189

Step-by-step explanation:

Given the table :

Source of Variation - - SS - - - df - - - MS - - - - F

Regression - - - - - -3177.17 - - -2 - - 1588.6

Residual - - - - - - - - ______ --17 - - -17.717

Total - - - - - - - - - - 3478.36 - - 19

Calculate the SSR, Sum of Square residual

The Sum of Square RESIDUAL (SSR), Mean Square Residual (MSR) and Degree of Freedom RESIDUAL (DFR) are related by the formular :

MSR = SSR / DFR

Hence,

SSR = MSR × DFR

Fr the table ;

MSR = 17.717 ; DFR = 17

SSR = (17.717 × 17)

SSR = 301.189
