Answer:

Jana has to pay a total of $43.43 and receives a change of $6.57.

Step-by-step explanation:

Step 1: Add the cost of the dress and blouse

25.98+14.99=40.97

Step 2: Sales tax is adding to the cost of the blouse and dress.

40.97+2.46=43.43

So her total cost is 43.43 dollars

If she pays with a 50 dollar bill, you need to see how much more that is than the actual cost.

50-43.43=6.57.

She will receive 6.57 dollars for change

So Jana has to pay a total of $43.43 and receives a change of $6.57.

Hope this helps!

your realized income is 3167.89/month, and your fixed expenses are 954.32/every 2 weeks. if you save 50% of your discretionary m

Answer:

<em>each month, you are saving 629.625</em>

<em />

Step-by-step explanation:

Your income is 3,167.89 each month.

Every 2 weeks, your fixed expenses are 954.32.

=> Average fixed expenses for 1 week is: 954.32 / 2= 477.16

As there are 4 weeks in each month, so that your fixed expenses each month are: 477.16 x 4 = 1,908.64

Your discretionary money for each month = Your monthly income - Your monthly fixed expenses = 3,167.89 - 1,908.64 = 1,259.25

=> Your discretionary money for each month is 1,259.25

As you save 50% of discretionary money each month, so that your monthly saving can be calculated as following:

<em>Monthly saving = Monthly discretionary money x 50% </em>

<em />

<em>So that each month, you are saving 629.625</em>

Let’s work with some actual data this time. Go online to research and find a set of real-world data in two variables. The data c

slega [8]

The quadratic regression equation that best fits the data set is y = 32.86x² - 379.14x + 1369.14

<h3>The data points </h3>

The following table of values represents the data points that would be used to solve this question:

x 3 4 5 6 7 8 9

y 470 416 403 226 314 338 693

Where:

x represents years since 2000
y represents the annual revenue of a manufacturing company in thousand dollars

<h3>The function of the dataset</h3>

The table of values illustrates a quadratic function.

The function would be calculated using a graphing calculator

From the graphing calculator, we have:

a = 32.86; b = -379.14 and c = 1369.14

A quadratic regression equation is represented as:

y = ax² + bx + c

So, we have:

y = 32.86x² - 379.14x + 1369.14

Hence, the quadratic regression equation that best fits the data set is y = 32.86x² - 379.14x + 1369.14

<h3>Why the function type was chosen?</h3>

From the table of values in (a), we can see that as x increases; the value of y decreases and then increases after it reaches a minimum.

This illustrates the behavior of a quadratic regression function
