Question

If you have a lowest score of 21 and a range of 47, your highest score will be:________

Answer 1

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

Answer 2

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:
$47 = H - 21\\\text{Adding 21 on both the sides}\\\\47 + 21 = H - 21 + 21\\68 = H\\H = 68$

Thus, the highest score for this considered case is 68
