We have been given an expression $(8.5\times 10^3)(2\times 10^5)$ . We are asked to find the solution to our given expression expressed as scientific notation.

Let us simplify our given expression.

Using exponent property $a^m\cdot a^n=a^{m+n}$ , we will get:

$8.5\times 2\times 10^3\times 10^5$

$17\times 10^{3+5}$

$17\times 10^{8}$

Now to write our answer in scientific notation, we need our 1st multiple between 1 and 10. So we will rewrite our expression as:

$1.7\times 10\times 10^{8}$

$1.7\times 10^{1+8}$

$1.7\times 10^{9}$

Therefore, our required solution would be $1.7\times 10^{9}$ .

Craig examines the effect of different genres of music, such as jazz, rock, rap, on task performance. Which type of measurement

ryzh [129]

Answer:

Nominal

Step-by-step explanation:

Data can be divided into 2 types:

Qualitative Data
Quantitative Data

Qualitative data represent some attribute or characteristic and cannot be measured or calculated. This type of data uses Nominal or Ordinal level of measurement.

Quantitative data is the data which can be measure or calculated. This type of data is expressed in Ratio or Interval scale.

Different genres of music represent an attribute, hence the data is Qualitative. Qualitative data which can put into some order is at Ordinal scale of measurement, while if the data simply represent the name or attributes it would be at Nominal Level.

Different genres of music cannot be put into some order and are just names, hence the measurement scale would be Nominal.
