15 624/1000 is it supposed to be sipplified?
Answer:
True.
Step-by-step explanation:
C(4, 3) means the number of combinations from 4 items taking 3 at a time. We are selecting 3 distinct items and it doesn't say anything about the order in which they are selected , so we use a combination formula not a permutation ( where order does matter).
C(4, 3) = 4! / 3! 1!
= 4*3*2*1 / 3*2*1*1
= 4.
There are 4 ways to select 3 items from 4.
Factors of 10: 1, 2, 5, and 10.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.
The greatest factor they have in common is 2.
You forgot the 1/2 Inches in that,
but the answer is 45 feet.
Its either 1.14 or 0.87 Hope this helps!
