D. Mean: 16 Median: 15 Mode: 9 Range: 18

Respuesta :

Answer is A.

To find the mean, you add, 9+10+15+18+18 and you get 70. You then divide them by 5 because that’s how many numbers you have and you get 14.

To find median, you rearrange the numbers from largest to smallest, (9,10,15,18,18) and the number in the middle is 15. That is your median.

The mode is 18 because you have more than one of it.

And the range, 18-9=9. You subtract the smallest number from the biggest and you get 9.
The answer is A hope this help xD
