There are 225 women in the race.
Step-by-step explanation:
Total people in the race = 234
Let,
x represents the number of women in race.
y represents the number of men in race.
According to given statement;
x+y=234 Eqn 1
x=25y Eqn 2
Putting x=25y in Eqn 1
Dividing both sides by 26
Putting y=9 in Eqn 2
There are 225 women in the race.

The number of ways to choose r objects out of n objects is:
C(n,r) = (n!)/(r! * (n-r)!)
The number of ways to choose 2 numbers out of a list of 9 numbers is:
C(9,2) = 9! / (2! * 7!)
= 9*8 / 2!
= 9*8/2
= 36

Step-by-step explanation:
<span>y - 7 = 3(3x - 11)
y - 7 = 9x - 33
y = 9x - 26
</span>answer
slope intercept form: y = 9x - 26
Consecutive angles of a parallelogram are supplementary, so:
This means and that .
Since opposite angles of a parallelogram are congruent,
