The equation used to predict how long it will take to receive a package through the mail is ŷ=0.5 + 0.02x1 + 0.85x2 days, where x1 is the distance to travel and x2 is the weight of the package. 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.

Answer :

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 : [tex]\widehat{y} =0.5 + 0.02x_1 + 0.85x_2[/tex]

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:

[tex]\widehat{y} =0.5 + 0.02x_1 + 0.85x_2[/tex]

y denotes time

[tex]x_1[/tex] denotes distance to travel

[tex]x_2[/tex] denotes weight of package

Now [tex]x_1 =224[/tex]

[tex]x_2=2.2[/tex]

Substitute the values in the equation

[tex]\widehat{y} =0.5 + 0.02(224) + 0.85(2.2)[/tex]

[tex]\widehat{y} =6.85[/tex]

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.
