Question 20 of 25 What is the quadratic regression equation that fits these data?

Number of seconds Height (in feet)
x. y
0. 11
1. 13
2. 13
3. 12
4. 9
5. 1

A. y = -3.07x^2 +0.41x + 15.65

B. y=19.61(0.69^2)

c. y= -2.34x^2 + 2.19x + 16.25

D. y = -1.11x^2 + 3.74x + 10.64

1) is right

step-by-step explanation:

da freeck kinda math is this just drop out

step-by-step explanation:

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.
