It might be composite or prime
eg 21 is composite and 23 is prime.
"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.
If 4 students are competing, then the race has
4! = 4 • 3 • 2 • 1 = 24
possible outcomes.
Answer:
the line is horizontal
Step-by-step explanation:
Note the y- coordinates of the 2 points the line passes through are equal.
This indicates that the line is horizontal and parallel to the x- axis
The equation of a horizontal line is y = c
where c is the value of the y- coordinates the line passes through.
Here the y- coordinates are 30, hence
Equation of horizontal line is y = 30
88 is 22 percent of 400. :-)
