Answer:
D
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.
Answer:
The directions followed for each intersection in order are North, 3 times East, 2 times South
and 3 times East.
Step-by-step explanation:
For the word NASSA in their algorithm we know the direction they take in the first intersection is North (N).
The second letter is A = EEE, which means in the 3 next intersections they follow the East.
The two Ss indicate they follow South in the next 2 intersections.
And finally, they follow the East in the last 3 intersections.
Their direction choices can be summarized in North-East-East-East-South-South-East-East-East.
