A group of students was given a bag with 100 marbles inside; some marbles were red and some were blue. The students were not allowed to look in the bag, so they each conducted experiments with 20 trials to try to determine the composition of the marbles in the bag. · Ms. Johnson picked a red marble 4 times · Ms. Masco picked a red marble 5 times · Ms. Armstrong picked a red marble 6 times Of the 100 marbles in the bag, how many are likely to be red?

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

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.
