Answer: Answer: 2.1 %
Step-by-step explanation:
Decrease = initial price - final price
% decrease = [ (initial price - final price) / initial price ] *100
% decrease =[ (2.89 - 2.83) / 2.89] * 100 = 2.08, which can be rounded to 2.1
Ivan gets £112.5(0) more than Tanya
99.2 = 100 + 1/2 (99.2 - 100) / 100 = 10 - 1/2 0.8/10 = 10 - 0.04 = 9.96

Step-by-step explanation:
Mean tells us the average (in this case, total marks/ total number of students).
Standard deviation tells us the spread of a set of data from its mean (how much it deviates from the mean).
Thus, standard deviation can be used to determine the consistency of a data. <u>The smaller the standard deviation, the more consistent the data is</u>.
Since 4S has the smallest standard deviation of 1, it shows the most consistent achievement in the test.
