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:
About 108 times
Step-by-step explanation:
Given:
An average soccer player travels 7 miles during a game
A typical field is 104 meters long.
To find:
How many times did the average soccer play travel the length of the field?
Solution:
An average soccer player travels during the game = 7 miles
First convert 7 miles into meters, 1 mile = 1609.34 meter
7 mile = 1609.34 \times 7 = 11265.41 m
Length of field = 104 meters
To find number of times average soccer player travel the length of the field, we will divide an average soccer player travels during the game by Length of field
11265.41 m
104 = 108.32
Therefore, about 108 times average soccer player travel the length of the field
Answer:
T = 290
Step-by-step explanation:
We can find the sum of all observations multiplying sample size (n) by sample mean (x).
Sum of all observations in the data set is,

5 odd numbers and 5 even numbers
since they can be repeated
5*5*5=first 3 digits
5*5*5=last 3 digits
in all
