Answer:
B.12.32
Step-by-step explanation:
- Let y be the widht of this triangle and x the length of it
From the first information we can write :
3y-x=2
from the second one :
2y+2x= 92
so our equation are :
Multiply the first one by 2 then add it to the second one to get rid of x :
- 6y-2x= 4
- 2y+2x+6y-2x= 92+4
- 8y = 96
- y= 12
- replace y by 12 to calculate the value of x
- x= 34
I’ll be honest, I have no idea what you are trying to say.
We apply the following property:
(x^n)^m = x^(n • m)
Let m = 2
(P^1/2)^2 = P^(1/2 • 2) = P
For this case we have the following function:
We must find the value of the function when x = -10
So, replacing we have:
Thus, the value of the function is 204 when x = -10
Answer:
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.
