Answer:
The above given statement is a fact.
Explanation:
A fact is nothing but a real statement which can never be false or imaginary or told in a future perspective. Let us analyze other options
Option 2: Opinion => An opinion can be anything and it can differ. A opinion is the way one people understand or perceive and give a statement according to that. An opinion always differs.
Option 3: Graphic => This is computer generated file, which can be true or false or imaginary. So this option is invalid
Option 4: Text => A text is nothing but words written together to convey a meaning. Though we feel like it suits the question, since the question speaks about the place, then it must definitely be fact and not just text.
Currency is the correct answer
Answer:
C. 14.4 kwhr.
Explanation:
To calculate the energy used by appliance first calculate the power. The formulae for calculating power(<em>P</em>) is 
, where V stands for voltage and I stands for current.
In the given problem, V = 240 volts and I = 15 amp. Therefore,
Now, formulae for calculating energy used i.e. work(W) is 
, where <em>t</em> is the time.
In the given question time is 4 hr. Therefore energy used will be,
Energy used (W) = 
.
Answer:
Option (B) Nominal is the correct option.
Explanation:
Nominal data set is the set of the heights of data measurement for the particular tax filing status. It also used for the labeling of the variables without allowing them to the quantitative data type. So, that's why the following option is correct.
Other options are wrong because the following statement is related to the Nominal data set.
Answer: 83.17
Explanation:
By definition, the dB is an adimensional unit, used to simplify calculations when numbers are either too big or too small, specially in telecommunications.
It applies specifically to power, and it is defined as follows:
P (dB) = 10 log₁₀ P₁ / P₂
Usually P₂ is a reference, for instance, if P₂ = 1 mW, dB is called as dBm (dB referred to 1 mW), but it is always adimensional.
In our question, we know that we have a numerical ratio, that is expressed in dB as 19.2 dB.
Applying the dB definition, we can write the following:
10 log₁₀ X = 19.2 ⇒ log₁₀ X = 19.2 / 10 = 1.92
Solving the logarithmic equation, we can compute X as follows:
X = 10^1.92 = 83.17
X = 83.17
