Answer:
e. m = 16.2; s = 1.27
Step-by-step explanation:
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we can assume that the distribution for X is given by:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Normal approximation
We need to check the condition in order to use the normal approximation.
So we see that we satisfy the condition and then we can apply the approximation.
If we appply the approximation the new mean and standard deviation are:
The best answer would be:
e. m = 16.2; s = 1.27
Answer:
The balance of your account after 5 years without more deposits or withdrawals will be $950.15.
Step-by-step explanation:
The compound interest formula is given by:

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.
In this problem, we have that:

So



The balance of your account after 5 years without more deposits or withdrawals will be $950.15.
Hey! I’m really struggling with this same class. Is there any way I can get in contact with you and we can share answers?
Hello!
To find our answer ,we will plug in each number of our domain and see what the outputs are. This will be our rangle.
-4(3.2)= -12.8
-2(3.2)= -6.4
0(3.2)=0
2(3.2)= -6.4
4(4.2)= 12.8
Now we order our numbers from least to to greatest.
-12.8,-6.4,0,6.4,12.8
Therefore, our answer is A.
I hope this helps!
