What are u asking, the difference?
D -9 because it has a -3 and its going to be the same - sign
Step-by-step explanation:
mean = sum of all data points / number of data points
(22+16+18+14+16+34+20)/7 = 140/7 = 20
median is the number, where half of the data points are smaller, and the other half are larger.
first we need to sort the data points
14, 16, 16, 18, 20, 22, 34
median = 18
mode is the data point occurring most often.
mode = 16 (occurring 2 times, while the others occur only once).
range is the difference between the largest and the smallest data point.
range = 34 - 14 = 20
Answer:
w=20
Step-by-step explanation:
Solve for w by cross multiplying.
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
