Answer:

It will take approximately 7 days to receive a package that is 224 miles away and weighs 2.2 pounds.

Step-by-step explanation:

Given : \widehat{y} =0.5 + 0.02x_1 + 0.85x_2

To Find : Use this equation to predict the how long it will take to receive a package that is 224 miles away and weighs 2.2 pounds.

Solution:

\widehat{y} =0.5 + 0.02x_1 + 0.85x_2

y denotes time

x_1 denotes distance to travel

x_2 denotes weight of package

Now x_1 =224

x_2=2.2

Substitute the values in the equation

\widehat{y} =0.5 + 0.02(224) + 0.85(2.2)

\widehat{y} =6.85

So, Time = 6.85 days

Hence  it will take approximately 7 days to receive a package that is 224 miles away and weighs 2.2 pounds.
