Answer:
6.5 * 10 ^ -9
Step-by-step explanation:
0.0000000065
Scientific notation means a* 10 ^b
where a is number between 1 and less than 10
Move the decimal 9 places to the right which means the power of 10 is negative since we moved the decimal to the right
6.5
The power of 10 is -9
6.5 * 10 ^ -9
Answer:
a. Types of computer software used in a database management system. =Qualitative
b. Life-lengths of laser printers =Quantitative
c. Brands of calculators used by 100 engineering students on campus =Qualitative
d. Mileage attained by 12 automobiles powered by alcohol= Quantitative
Step-by-step explanation:
Data is described as quantitative when it deals with numeric values whereas qualitative data is categorical in nature. Quantitative data tells us how much, how many, or the frequency of occurrence of certain variables. Qualitative data provides answers to the what, why, which, and where questions.
1. Types of computer software are not numeric variables as they answer the 'what' question.
2. Length deals with numbers, so the life-lengths of laser printers is a quantitative variable.
3. Brands of calculators are categorical data and are thus qualitative.
4. Mileage is a numerical variable and is thus quantitative.

Answer:
The ordered pair make both inequalities true
Step-by-step explanation:
we have
------> inequality A
------> inequality B
we know that
If a ordered pair satisfy both inequalities
then
the ordered pair is a solution of both inequalities
we're going to verify every case
<u>case A)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is not true
therefore
The ordered pair does not make both inequalities true
It's not necessary to verify the B inequality
<u>case B)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is true
<u>Inequality B</u>
------> is true
therefore
The ordered pair make both inequalities true
<u>case C)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is not true
therefore
The ordered pair does not make both inequalities true
It's not necessary to verify the B inequality
<u>case D)</u> point
Substitute the values of x and y in both inequalities
<u>Inequality A</u>
------> is not true
therefore
The ordered pair does not make both inequalities true
It's not necessary to verify the B inequality
