Answer: 68
Step-by-step explanation:
range=47 lowest score = 21 let highest score =x
Range=highest score - lowest score
47 = x - 21
x = 47 + 21
x = 68
Therefore the highest score is 68
Range is the difference of highest and lowest value. The highest score for this considered case is 68
How to find the range of a data set?
To find the range of a data set, we need the maximum and minimum value of the data set.
Then, we get:
Range = Maximum value - Minimum value.
For this case, we have:
- Range of the scores = 47
- Lowest score = 21
- Highest score = 'H' (say)
Then, by the definition of range, we get:
[tex]47 = H - 21\\\text{Adding 21 on both the sides}\\\\47 + 21 = H - 21 + 21\\68 = H\\H = 68[/tex]
Thus, the highest score for this considered case is 68
