Answer: t = - 5 ∈ = ( -∞ , -4 )
Step-by-step explanation:
The standard form of O.D.E is written as :
+
Equation given :
+
=
,
The first thing to do is to write the O.D.E in standard form , that is we will divide through by , so we have
With this , we can see that and
are both continuous in the same domain. Therefore , the intervals are :
= ( -∞ , -4 )
= ( - 4 , 4 )
= ( 4 , -∞ )
recall that y(−5) = 1 , then t = -5
This means that :
t = - 5 ∈ = ( -∞ , -4 )
Answer:
B. the trials must be dependent
Step-by-step explanation:
The image for the question is attached.
The missing options are;
A. The probability of a success remains the same in all trials.
B. The trials must be dependent.
C. Each trial must have all outcomes classified into two categories.
D. The procedure has a fixed number of trials.
For a binomial distribution probability, the event must be repeated for a number of time (n) and the probability of success (q) must be the same during each trial.
Binomial distribution probability has two possible outcome: success (p) or failure (q). The event are also independent of each other.
The formula for a binomial distribution probability is given as:
P(X=x) = nCx (p ^ x) (q ^ (n-x))
From the above, we can see that the answer is:
B. the trials must be dependent
