Answer: A. 21</h3>
=======================================
C(n, r) = (n!)/(r!*(n-r)!) is the combination formula
C(7, 5) = (7!)/(5!*(7-5)!)
C(7, 5) = (7!)/(5!*2!)
C(7, 5) = (7*6*5!)/(5!*2!)
C(7, 5) = (7*6)/(2!) ..... note the "5!" terms divided and canceled
C(7, 5) = (7*6)/(2*1)
C(7, 5) = 42/2
C(7, 5) = 21
Answer:
Step-by-step explanation:
3/4 of total = 45
therefore, 1/4 took bananas
the ones taking bananas are 3 times less than those who took apples.
so we get 45/3 = 15 people picking bananas
The mixed number is 4 5/12.
I just took the test. The answer is y=250(4^x)
