Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit. (1 point)

Group of answer choices

No, the equation is not a good fit because the sum of the residuals is a large number.

No, the equation is not a good fit because the residuals are all far from zero.

Yes, the equation is a good fit because the residuals are not all far from zero.

Yes, the equation is a good fit because the sum of the residuals is a small number.

step-by-step explanation:

9 x 8 divided by (5-3)=36

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.
