Answer:
P(X = 4) = 0.1876
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this question:
We want P(X = 4). So
Answer:
Step-by-step explanation:
(2n+ 2)(6n+ 1)
2n+6n=8n
1+2=3
=8n+3
Answer:
V>-8
Step-by-step explanation:
The given inequality is :
4-V>12
Subtracting 4 from both sides.
4-V-4 > 12-4
-V>8
or
V>-8
So, the value of V is more than -8.
Answer:
C. (3,-3)
Step-by-step explanation:
5x + 3y = 6
5(3) + 3(-3) = 6
15 + (-9) = 6
therefore point lies on the line
