Answer:
r = 1
Step-by-step explanation:
Solve for r
by simplifying both sides of the equation, then isolating the variable.
45 times the numerator plus the denominator is most likely going to equal the same amount as if it were doubled.
<u>Answer</u>:
3003 number of 5-member chess teams can be chosen from 15 interested players.
<u>Step-by-step explanation:</u>
Given:
Number of the interested players = 15
To Find:
Number of 5-member chess teams that can be chosen = ?
Solution:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula
where
n represents the total number of items,
r represents the number of items being chosen at a time.
Now we have n = 15 and r = 5
Substituting the values,







The probability would be 2/6 or 1/3
Answer:
k = -3
Step-by-step explanation:
1) Simplify
5+20k+7k=28k+8
2) Combine the k's
5+27k=28k+8
3) Subtract 27k on both sides
5=k+8
4) Subtract 8 on both sides
-3=k or k= -3
