Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, co

ruslelena [56]

Answer:

<u>Quantitative.</u>
<u>Discrete.</u>
<u>Interval Scale.</u>

Step-by-step explanation:

The IQ scores are measured numerically. This makes it quantitative data. Quantitative data provide numerical measures which can be used to perform arithmetric operations such as addition, subtraction, multiplication and division. Results from these kind of data can be used to provide meaningful and explanatory results to certain phenomena.
IQ scores are discrete because they are always expressed as integers. that is in whole numbers and not in fractions e.g 100, 120, 60.
The level of measurement is on an interval scale because the difference between values have meanings. Larger values mean higher IQ. for example, the difference in IQ numbers between two people for represents something real.

Ray is buying some ginger roots to brew some fresh ginger ale. The price of the ginger root is g, and Ray has a coupon for 10% o

kondaur [170]

Step-by-step explanation:

Comparision: Let say you buy chocolate that cost $1. And there was luckily a coupon, for 10% off.

That means after applying the coupon, you will only pay 90% of the original price. Which is

$0.9(1) = 0.9$

which equals 90 cents.

So let go back to this problem and apply similar thinking.

The price of the original root is g, so for the original price column, check the 3rd cell, g.

Use our comparision problem, by applying the coupon to the chocolate, you will save

$1 - 0.9 = 0.1$

which is 1/10 of the original price.

In this equation, we can represent this as 0.1g.

So for the second column, shade in 5th cell, 0.1g.

The price would be

$(0.9)1 = 0.9$

So our equation for this equation will be

0.9g.

So for third column, shade in 1st cell, 0.9g.
