Answer:
Step-by-step explanation:
Given that a random sample of records of home sales from Feb. 15 to Apr. 30, 1993, from the files maintained by the Albuquerque Board of Realtors gives the Price and Size (in square feet) of 117 homes.
A regression is done to predict Price (in thousands of dollars) from Size
Hence
a)we have size as independent variable and price as dependent variable. Units for size are square feet and price are in 1000s of dollars.
b) Slope will have unit has 1000dollar/sqft
c) Slope is positive since price is directly variant over size.
So slope will be positive.
Answer:
6x-8
Step-by-step explanation:
Subtract 8 from 4 to get −4.
13x−4+6x−13x−4
Combine 13x and 6x to get 19x.
19x−4−13x−4
Combine 19x and −13x to get 6x.
6x−4−4
Subtract 4 from −4 to get −8.
6x−8
Volume of a cylinder = πr²h
Volume of the cylinder = π (2 3/16)² (3)
Volume of the cylinder= 45.10 in³
Answer: 45.10 in³
