Answer:
False
Step-by-step explanation:
The given statement is:
The coefficient of x^ky^n-k in the expression of (x+y)^n equals (n-k/k)
This is a false statement
Reason:
When we do expansion of (x+y)^n by binomial theorem we get the following solution:
(x+y)^n = nCk x^k y^n-k
This shows that the coefficient of x^ky^n-k is nCk which is equivalent to n!/(n-k)! k!
Therefore it is a false statement....

Answer:
330,000
Step-by-step explanation:
if the underlined digit is 9, then the six rounds the 9 up to a 10, making the rounded number amount to 330,000.
7 hours 00 minutes minus 46 minutes=6 hours 14 minutes or 7:00-00:46=6:14 am
