Please I really need help

1. The inside of a large industrial container has a height of 3 metres, measured

correct to the nearest 10 cm.

It is used to hold a single stack of flat metal plates.

Each metal plate has a thickness of 4 centimetres, measured correct to the

nearest millimetre.

(a) Find the greatest possible number of these plates that could be stacked in the

container.

[3]

(b) Damian states that it may not be possible to stack 73 of these plates in the

container.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

i need points

step-by-step explanation:
