Answer:
a. 104
b. 102, 104, and 105
Step-by-step explanation:
a. There are 13 data points plotted on the dot line. The median lies between the 6th and 7th data point.
Thus, on the dot line, the 6th and 7th data points both fall on 104.
Therefore, median = 104
b. The dot plot shows the high temperatures that occurred more than one day are:
102, 104, and 105
When you lose 3 points for 8 questions in a row, you have lost:
8 x 3 points = 24 points lost
The simplified expression is 6+3i
