1. Adjacent, complementary, vertical, or supplementary
Nat2105 [25]
1) ABF & EBD ARE SUPPLEMENTARY ANFLES (ABF + EBD =180)
2) FED=?. Note that FED=GEC=(16x-8).
Now in Triangle FED, the relation is (16x-8) + 35 + (2x+9) =180

The five-number summary for the number of teams in each of Brad's fantasy football leagues is shown in the following table.
Westkost [7]

Answer:

The correct option is (C) 10.

Step-by-step explanation:

The five-number summary for the number of teams in each of Brad's fantasy football leagues is as follows:

Minimum: 4

<em>Q</em>₁: 7

Median: 10

<em>Q</em>₃: 14

Maximum: 18

The minimum value is the smallest value in the data set.

The first quartile (<em>Q</em>₁) is the value that is less than 75% of the observations.

The median is the middle most value of the data set. It is the value that is less than 50% of the observations.

The third quartile (<em>Q</em>₃) is the value that is less than 25% of the observations.

And the maximum value is the largest value in the data set.

So, the five-number summary suggests that about 50% of Brad's fantasy football leagues have fewer than 10 teams.

Thus, the correct option is (C).
