<u>Options:</u>
- A. 8/x + 1, correct
- B. 8x + 1, incorrect
- C. 8 - x + 1, incorrect
- D. 8 / (x - 1), incorrect
Answer:
C and B.
Step-by-step explanation:
f(x) = 4 - x^2.
The degree of f(x) is 2, which means it is a quadratic graph. The coefficient of x^2 is negative, which means the curve is pointing downwards. The only curve that satisfies this is Graph C.
f(x) = 2^x + 5.
Notice that 2^x is positive for all real values of x. Therefore the answer is Graph B.
Answer:
The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side.
Answer:
3=47x86= and 4838x7694
Step-by-step explanation:
Answer:
The random variables in this case are discrete since they have a Multinomial distribution.
The probability mass function for a discrete random variable X is given by:
Where are 
are possible values of X.
The joint probability mass function of two discrete random variables X and Y is defined as
P(x,y) =P(X=x,Y=y).
It follows that, The joint probability mass function of 
is :
