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
The correlation that is obtained when the pearson correlation is computed for data that have been converted to ranks is option A) The Spearman correlation.
<h3>What is Spearman correlation used for?</h3>
Spearman's correlation is known to be one that tends to look into or measures the strength and way of monotonic relationship between two variables.
It is one that is a nonparametric measure that is often known to be rank correlation and it tends to examine how well the association between two variables can be said to using a monotonic function.
Hence, The correlation that is obtained when the pearson correlation is computed for data that have been converted to ranks is option A) The Spearman correlation.

Answer:
A unique identifier for a mobile phone
Explanation:
There are different codes and tracking number assigned to different devices such as laptop, mobiles and other devices. The purpose of this task is to make sure the security of device in all aspects. The tracking number that is used to track mobile phone is named as IMEI that stands for International Mobile Equipment Identity.
IMEI is the the unique identity of mobile phone device that consists of 15 digits. It is the unique number that is assigned to phones.
Answer : The center lane is designated for left turns
Explanation: This lane is used so that drivers would pull into in order to turn left when a clear merge is available. Its main purpose is not to cause traffic jam while waiting for the chance to turn left. It is illegal to use this lane for any other purposes
