Answer:
The correct option is;
False
Step-by-step explanation:
The coefficient of x^k·y^(n-k) is nk, False
The kth coefficient of the binomial expansion, (x + y)ⁿ is 
Where;
k = r - 1
r = The term in the series
For an example the expansion of (x + y)⁵, we have;
(x + y)⁵ = x⁵ + 5·x⁴·y + 10·x³·y² + 10·x²·y³ + 5·x·y⁴ + y⁵
The third term, (k = 3) coefficient is 10 while n×k = 3×5 = 15
Therefore, the coefficient of x^k·y^(n-k) for the expansion (x + y)ⁿ =
not nk
Answer:
18
Step-by-step explanation:
Every number is a result of adding 7 to the previous number.
Answer:
y=2
Step-by-step explanation:
Given the function y = 2-x ^ 2, we have that the horizontal asymptote is y = 2 since for x = 0 y = 2, that is, it is a line parallel to the axis = 0X where y has a value k, in this case y = 2
Answer: Increases in X tend to be accompanied by increases in Y
Step-by-step explanation:
The option given that indicates a positive value for a correlation is that an increases in X tend to be accompanied by increases in Y.
When two variables are said to be positively correlated, it simply means that the variables move along the same direction. As one variable increase, the other variable too will slow increase and vice versa.
Answer:
Add all the average amounts of items in each bag and you should get 23. Then, divide it by 3 since you are working with 3 numbers.
