There are 10 values in the data set. Conveniently, they are sorted for you. The median (central line in the box) will be the average of the middle two numbers:
.. (20 +22)/2 = 21 . . . . . . . . matches the 2nd and 4th selections
The first quartile (the left end of the box) will be the middle number of the first group of 5, so is 9. This matches the 4th selection only.
The 4th selection is appropriate.
Answer:
The third term is 11.
The first negative term is the fifth term.
Step-by-step explanation:
If the nth term of the sequence is given by the expression 20-n^2, to find the third term, we just need to use the value of n = 3 in the expression:
20 - (3)^2 = 20 - 9 = 11.
To find which term is the first to have a negative value, we can solve the inequation 20 - n^2 < 0:
20 - n^2 < 0
n^2 > 20
n > 4.47
The first term to have a negative value is the fifth term:
20 - 5^2 = 20 - 25 = -5
It will be 1/6 because it one side out of 6 tries
