In the following multiple regression equation, what is value of x1x1 when x2x2 = 16 and ˆyy^ is estimated to be 72.5? ˆy=142+19x1−18x2y^=142+19x1-18x2 x1x1 =

The cost to manufacture x items in one hour can be modeled by C(x)=2.32e^0.018x dollars. How many items can be produced in one hour if the manufacturing budget is $8,447? Round to the nearest integer.

House price y is estimated as a function of the square footage of a house x and a dummy variable d that equals 1 if the house has ocean views. The estimated house price, measured in $1,000s, is given by yˆy^ = 119.60 + 0.14x + 54.80d.   a-1. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 1,600. (Do not round intermediate calculations. Round your final answer to 2 decimal places.) predicted price=    a-2. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 3,200. (Do not round intermediate calculations. Round your final answer to 2 decimal places.) predicted price=
