The NFL needs to buy a new batch of official coins for the pre-game coin flip. They get 3 sample coins from a manufacturer based in Sweden, and tell their intern to flip all 3 coins simultaneously multiple times and count the number of heads each time. The intern gets: 0 heads 5 times; 1 head 10 times; 2 heads 9 times; and 3 heads 6 times. Should the NFL buy coins from that manufacturer, i. e., are the coins fair or not

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

multiple all that

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.
