A real estate magazine reported the results of a regression analysis designed to predict the price (y), measured in dollars, of residential properties recently sold in a northern Virginia subdivision. One independent variable used to predict sale price is GLA, gross living area (x), measured in square feet. Data for 157 properties were used to fit the model, = [Math Processing Error]

The results of the simple linear regression are provided below. = [Math Processing Error]
Interpret the estimate of [Math Processing Error], the y-intercept of the line.

let take the method  ^y = 22.5x +96,600  

Step-by-step explanation:

All residential properties in Virginia will sell for at least $96,600.

For each 1-sq ft rise in GLA, a property's sale price is expected  to go above $96,600.

Sale prices as observed would fall within$96,600 of the least squares line., as about 95% is discovered.

 There is no value given, since a gross area of zero a not a constant value

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
