First you must know that is i∧2= -1
x∧3-4x∧2+4x-16 = x∧2 (x-4) + 4 (x-4) = (x-4) (x∧2+4) = (x-4) (x∧2-(-4)) =
= (x-4) (x∧2-(-1) *4) = (x-4) (x∧2- i∧2*2∧2) = (x-4) (x∧2-(2i)∧2) = (x-4) (x-2i) (x+2i)
Good luck!!!
Answer:
352x^2
Step-by-step explanation:
40\times 1.25x\times 2.20x\times 3.2040×1.25x×2.20x×3.20
(40)1.25x2.20x3.20
+ − . ln > <
× ÷ / log ≥ ≤
( ) logx = %
1 Take out the constants.
(40\times 1.25\times 2.20\times 3.20)xx(40×1.25×2.20×3.20)xx
2 Simplify 40\times 1.2540×1.25 to 5050.
(50\times 2.20\times 3.20)xx(50×2.20×3.20)xx
3 Simplify 50\times 2.2050×2.20 to 110110.
(110\times 3.20)xx(110×3.20)xx
4 Simplify 110\times 3.20110×3.20 to 352352.
352xx352xx
5 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

Answer: c. Nominal
Step-by-step explanation:
Level of measurement determines the nature of description .
The four levels of measurements scales are
1. Nominal scale
- Categorize the data on the basis of the quality such as Gender, color, etc.
2. Ordinal scale
- Order attributes according to their ranks. For example : 1 < 2 < 3 .
3. Interval scale
- Describe the feature of the difference between any two categories. For example : Fahrenheit scale to measure temperature.
4. Ratio scale
- Consist of the features of nominal, ordinal, and interval measures but in includes a "true zero" point.
For example : Age.
∴ A<u> nominal</u> variable is a qualitative variable such that there is no meaningful ordering or ranking of the categories.
Hence, the correct answer is c. Nominal .
