Question

The number of internet users in the United States(in millions), y, at x years since 1995 is given by y = 19.7917 + 20.7167xa)

Answer 1

Answer:

19.8 ; 61.2 ; 227.0

Step-by-step explanation:

Given the regression model :

y = 19.7917 + 20.7167x

Number of internet users in 1995, x = 0

Put x = 0 in the equation :

y = 19.7917 + 20.7167(0)

y = 19.7917 + 0

y = 19.7917

y = 19.8

b.)

1997, x = 2

Put x = 2

y = 19.7917 + 20.7167(2)

y = 61.2251

y = 61.2

c.)

2005, x = 10

y = 19.7917 + 20.7167(10)

y = 226.9587

y = 227.0
