Over the past few years the percentage of students who leave lakeland college at the end of the first year has increased. last year lakeland started a voluntary one-week orientation program to first-year students adjust to campus life. if lakeland is able to show that the orientation program has a positive effect on retention, they will consider making the program a requirement for all first- year students. lakeland’s administration also suspects that students with lower gpas have a higher probability of leaving lakeland at the end of the first year. in order to investigate the relation of these variables to retention, lakeland selected a random sample of 100 students from last year’s entering class. the data are contained in the data set named lakeland; a portion of the data follows.

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.
