x = -2, 5.
Step-by-step explanation:
|2x - 3| = 7

x = -2.
Answer:
Both the mean and median will decrease, but the mean will decrease more than the median.
Step-by-step explanation:
Removing the wheel of cheese will decrease the median a little bit, because the median shifts from between two data points to the lower of the two data points:
With the wheel of cheese, the median is the middle number, but there's no middle number in this data set! So, to find the median we take the mean of the two middle numbers, $4.79 and $5.19 which is $4.99.
Without the wheel of cheese,
Removing the wheel of cheese will decrease the mean significantly, because the total cost will decrease by $39.99, and the number of items decreases by only 1.
Arranging them in ascending order :
21 , 21 , 30 , 44, 49, 52
Median = (30 + 44) ÷ 2
Median = 37 mins
