=3(3z)2-3
=3(9z2)-3
=27z^2-3
=3(9z^2-1)
=3(3z+1)(3z-1)
Answer:
The quantitative variables in this case are:
A. Speed
D. GForce
E. Height
G. Duration
H. Numinversions
J. Length
Step-by-step explanation:
One criteria to differentiate qualitative variables from quantitative variables is to determine if mathematical calculations over these variables makes sense.
If it makes sense, it is a quantitative variable.
For example, binary variables, although they can be represented by 0 and 1, would be a qualitative variable.
The quantitative variables in this case are:
A. Speed
D. GForce
E. Height
G. Duration
H. Numinversions
J. Length
They all will be represented by numbers for which mathematical operations make sense.
Answer:
7%
11%
5%
14%
Step-by-step explanation:
To find a numbers percentage of another number you simply divide the smaller number by the bigger number then move the decimal point to the right 2 places.
Percentage of workers who prefer chicken soup who are part-time: 35÷500 = 0.07 move the decimal 2 to the right to get 7%.
Percentage of full-time workers who prefer mushroom soup: 55÷500 = 0.11 move the decimal 2 to the right to get 11%.
Percentage of workers who prefer lintel soup who are full-time: 25÷500 = 0.05 move the decimal 2 to the right to get 5%.
Percentage of part-time workers who prefer tomato soup: 70÷500 = 0.14 move the decimal 2 to the right to get 14%.
Hope this helps! :)

Answer:
25, 26, 27. Just divide 78 by 3. And then go one lower integer and one higher integer to make the numbers consecutive.
