7 The table shows the weights of some chickens. Weight, w kg Frequency
1.5 ≤ w < 2 7
2 ≤ w < 2.5 12
2.5 ≤ w < 3 6
3 ≤ w < 3.5 14

(3 marks)
b Find the class that contains the median.

c Find the modal class.

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

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.

answer: that means that there is to perpendicular
