gabriel has three number cards. The minimum of her three cards is 21, the range is 38 and the median is 43 what is the mean of gabriels cards?



Answer :

41

======================

We need to first identify the three cards.

The minimum value is 21.

The range is 38, meaning the difference between the highest and lowest card is 38. Therefore, the highest card is:

  • 21 + 38 = 59

Since there are only three cards, the median value, which is the middle card, is given as 43.

So, the three cards are 21, 43, and 59.

Now we can calculate the mean:

  • Mean = (21 + 43 + 59) / 3 = 123 / 3 = 41
