horrorfan [7]

Answer:

The correct options are:

Four families said they ate out twice the previous week.

One family said they ate out 5 times the previous week.

The median best represents the data set.

Step-by-step explanation:

We are given a data set as:

4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1

On arranging this data set in the frequency table we get:

Number of times they went for dinner Number of families

0 2

1 3

2 4

3 1

4 2

5 1

6 1

Hence, the range of the number line is between 0 to 6.

Also there are 4 dots above 2.

Hence, Four families said they ate out twice the previous week.

Also there is one dot above 5.

Hence, One family said they ate out 5 times the previous week.

The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.

Hence, the data set is not symmetrical.

Also we know that the median of the data is the central tendency of the data and always best represents the data.

Hence, The median best represents the data set.

Answers:

a) See the table below

b) The equation is $y = 32000(1.01125)^x$

c) $40,024.02

d) See the graph below

=========================================================

Explanations:

Start with part (b) where I detail how to get the equation.

Once the equation is found, plug in x = 0 to get

$y = 32000(1.01125)^x\\\\y = 32000(1.01125)^0\\\\y = 32000\\\\$

Repeat for x = 1

$y = 32000(1.01125)^x\\\\y = 32000(1.01125)^1\\\\y = 32360\\\\$

Repeat for x = 2, x = 3, x = 4 and x = 20 to get the table shown below.

-----------------------

The template for any exponential equation is $y = a(b)^x$

a = starting amount = 32000

b = growth factor

The annual interest rate is 4.5%

We compound quarterly, so the quarterly rate is (4.5%)/4 = 1.125% which converts to the decimal form 0.01125; adding one to this leads to the growth factor of b = 1.01125

We go from $y = a(b)^x$ to $y = 32000(1.01125)^x$

-----------------------

Plug in x = 20 to represent 20 quarters have elapsed (aka 20/4 = 5 years)

$y = 32000(1.01125)^x\\\\y = 32000(1.01125)^{20}\\\\y \approx 32000(1.25075052084381)\\\\y \approx 40024.016667002\\\\y \approx 40024.02\\\\$

The investment would be worth $40,024.02 after five years, aka twenty quarters.

-----------------------

See below for the graph. I'm using GeoGebra to make the graph. Another option is Desmos. It's preferable to use technology than to graph by hand. If you wanted to graph by hand, then you'd plot each of the points found in the table. Then draw a curve through all those points.
