Which is an example of a survey involving quantitative data?
a. the favorite food of each person
b. the number of cavities each person has had
c. the color of the walls in each person’s bedroom
d. the type of car that each person owns

B. The number of cavities each person has.

Step-by-step explanation:

We are required to find the survey consisting of quantitative data.

'Quantitative data are measures of values and are expressed in numbers'.

Thus, the survey having the data in the form of numbers will be an example of an quantitative data.

From the options, we see that,

'The number of cavities each person has' will give the result in the form of numbers.

All others would not provide numbers as the data.

Hence, the correct example of an quantitative data is,

B. The number of cavities each person has.

B. the number of cavities each person has had

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
