22 = 10 + 10 + 1 + 1 so it is XXII
The perimeter is: 1+10+1+10 = 22 cm
There is not a single mode, as no number appears more than any other, but three numbers appear more than once and the same amount of times, so 22, 18 and 6 can all be said to be the mode.
The mean is 21 and 1/3 The median is 22 The mode is 24

No, it is in general not true - for example for uniform distribution on [0,1] every number in the interval is a mode, but the mean is 1/2. The correct answer would be that a symmetric unimodal distribution has one mode equal to the mean (but may have modes elsewhere).
1 million = 10⁶ = 1,000,000 22 million = 22 × 1 million = 22 × 10⁶ = 22 × 1,000,000 = 22,000,000 = 2.2 × 10⁷
22 = 10 + 10 + 1 + 1 so it is XXII
10+1+10+1=22
The perimeter is: 1+10+1+10 = 22 cm
yes it can. Imagine the set 1,1,1,1,1,1,1,1,1,1 well, the mode is obviously 1. there are ten 1s and 10*1/10=1 so the mean is one the median would be (1+1)/2=1 so the data has the same mean, medain and mode.
There is not a single mode, as no number appears more than any other, but three numbers appear more than once and the same amount of times, so 22, 18 and 6 can all be said to be the mode.
