between x and y?
Regression 1)
y = ax + b
a = -15.5
b=3
r= -1.0333
Regression 2)
y = ax + b
a = -7.5
b = -4.3
r = -0.997
Regression 3)
y = ax + b
a = -17.8
b = 12
r = -0.7279
Regression 4)
y = ax + b

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.
