Answer:
7
Step-by-step explanation:
x + 3 : x + 8 : : 2 : 3
(x + 3) \times 3 = (x + 8) \times 2 \\ 3x + 9 = 2x + 16 \\ 3x - 2x = 16 - 9 \\ x = 7 \\ x + 3 = 7 + 3 = 10 \\ x + 8 = 7 + 8 = 15 \\
10 : 15
2 : 3
Answer:
The mean will change. The range will change.
Step-by-step explanation:
The outlier is 4, it's the one number in the data that isn't close to the other numbers.
The data without the outlier will be 7, 9, 9, 10.
Mode: The mode will still be 9. It is still the number that appears the most in the data.
Median: The median WON'T change. The data is now one value shorter, but the median will still be 9. Before it was 9, and now it's still 9 ((9+9)/2).
Mean: The mean will change because we're excluding one value. Before, the mean was 7.8 (4+7+9+9+10=39, 39/5 = 7.8). NOW it is 8.75 (7+9+9+10=35, 35 / 4 = 8.75).
Range: The range will change. Before it was 10-4, now it is 10-7. The range was originally 6 and now it's 3.
