Ineed plz i’ve been up for 2 days on this guys worth 10 !

17%

There are 30 students total. Out of those, there are 5 seniors. As a fraction: the probability is 5/30 or 1/6.

To convert to a percentage, you divide 5 by 30:

5/30=0.1666666667 which rounds to 0.17

To convert to a percentage, you must multiply the decimal by 100:

0.17*100=17

There is a 17% chance that the selected student will be a senior.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

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.
