The Number of text messages sent in a month is 1.68 × 
Step-by-step explanation:
Step 1 :
Total number of teenagers in United States = 21 million
Average text messages sent per month = 800
We need to find the number of text messages sent each month
Step 2 :
The number of text messages in a month can be computed by taking the product of the total number of teenagers and average messages sent per month
Therefore
Number of text messages that is sent in a month = 21 million × 800
= 21 × 
× 800
= 168 × = 1.68 ×
Step 3 :
Answer :
The Number of text messages that is sent in a month is 1.68 ×
360 - because a right angle is 90° and there are 4 right angles in a circle , 90 x 4 = 360
There isn't any piece of data during Taylor's experiment which can be taken as qualitative. Thus, correct choice is: Option D: None are qualitative.
<h3>What is qualitative data?</h3>
Qualitative data tells about the quality or characteristic. It is tough to express it numerically or not at all expressible numerically. They are usually catagorical.
In contrast, there is quantitative data which can be expressed numerically.
The problem is missing its option, which are:
- mass of the cars
- degree of the ramp incline
- time in seconds
- none are qualitative
Mass can be measured (in kgs, grams etc), degree of inclination can be measured (in radians, degree etc), time can be measured (in seconds, minutes etc).
Thus, there isn't any piece of data during Taylor's experiment which can be taken as qualitative. Thus, correct choice is: Option D: None are qualitative.
