Answer:
The true statement is " The spread is from 1 to 6."
Explanation:
Consider the provide information.
First we will draw the dot plot as shown in the figure.
Now consider the options.
The data is not symmetric as for the symmetry the dots over 1 should be equal to the dots over 6. i.e 4.
Now find the center of the data by calculation the median of the data.
There are 16 dots in total which is an even number.
So, now we will find the average of the two middle values.
This will be the 8th and 9th value average for the given data set of 16 values.
Count from left to right the 8th and 9th values are both 4.
Hence, the center of the data is 4.
The second statement is false.
The peak of the data is at 6.
The third statement is false.
The spread is from 1 to 6 as we can see in the figure shown below.
Therefore, the true statement is " The spread is from 1 to 6."
Answer:
The correct answer is A. $18,276
Explanation:
First you have to calculate how much you'd end up having at the end of the 25 years period in your savings account.
You calculate the total amount saved for each year, using the formula:
Where
is the total amount in the savings account for this period.
is the total amount in the savings account from the previous period.
is the interest rate.
are the annual deposits being made into the savings account.
Therefore for the first year you'd do:
For the second year:
And so on. You can help yourself calculate the value of this series using programs like Excel.
I have attached an Excel file that has a table with the savings values for each of the 25 years.
So, the 25th year you’ll have $365,529.70 in your savings account. Now you simply divide this number by 20 (that will be the number of years you’ll be withdrawing the same dollar amount from your savings account):
In conclusion, you’d be able to withdraw $18,276.485 each year for the following 20 years after the 25th deposit, if all withdrawals are the same dollar amount.
