If the total for this month's credit purchases is $550 at 24% annual interest, what is the total balance for the month after one
umka2103 [35]

Answer:

The total balance for the month after one month of interest accrues is $561 .

Step-by-step explanation:

Given as :

The principal credit in account = p = $550

The rate of interest = 24% annual

The time period = 1 month = \dfrac{1}{12} year

Let The Amount after one month of interest = $A

<u>Now, From Simple Interest method</u>

Simple Interest = \dfrac{\textrm principal \times \textrm rate\times \textrm time}{100}

Or, s.i = \dfrac{\textrm p \times \textrm r\times \textrm t}{100}

Or, s.i = \dfrac{550\times 24\times \frac{1}{12}}{100}

Or, s.i = \dfrac{13200}{1200}

Or, s.i = 11

∵ Amount = Principal + interest

So, A = s.i + p

Or, A = $11 + $550

∴  A = $561

So, The amount after one month on interest = A = $561

Hence, The total balance for the month after one month of interest accrues = A = $561 . Answer

During the semester, all the students in a statistics class kept track of the number of mailings they received from a predatory
Verdich [7]

Answer:

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21

We have a sample size of n =9

And in order to find the 75th percentile we need to find the position for this percentile with this formula:

n_{75} = 0.75* 9= 6.75\approx 7

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:

x_{75} = 18

Step-by-step explanation:

For this case we have the following data:

16 17 11 21 15 14 17 18 19

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21

We have a sample size of n =9

And in order to find the 75th percentile we need to find the position for this percentile with this formula:

n_{75} = 0.75* 9= 6.75\approx 7

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:
