Answer:

y is 4

Step-by-step explanation:

so the equation is y = kx ( k is the constant)

We've been given x as 5 & y as 10 so we can use these values to find the constant .

10 = k(5)

k = 2

so now , we can find y

y = 2 × 2

y = 4

if the linear model applies the function f(x) = 1.3x + 9.2, what is the predicted value and residual when the tree is 5 years ol

garri49 [273]

Answer:

predicted: 15.7

residual: 1.3

Step-by-step explanation:

In x-axis, age of the tree is represented, and in y-axis, height of the tree is represented. When the tree is 5 years, x = 5, and the predicted value is:

f(5) = 1.3(5) + 9.2 = 15.7

Residual value is computed as follows:

residual = observed - predicted

residual = 17 - 15.7 = 1.3
