Solution :
It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :
1. 
2. 
Now consider,
⇒ 
⇒ 
⇒ 
⇒ 
= 0.2
Therefore, the value of T is 0.2
Thus, option (c) is correct.
Answer:
359.94 = 59.99 * X
Step-by-step explanation:
The situation is determined by the following equation:
T = M * X
Being M the monthly value, that is to say 59.99
T the total value, that is 359.94
And X would be the number of months, and at the same time the variable.
In this case it would be like this:
359.94 = 59.99 * X
If we solve for X, we are left with:
X = 359.94 / 59.99
X = 6
That is to say that Megan went to the gym for 6 months of the year

The equation of the least-squared regression line is: In(Element) = 2.305 - 0.101(Time).
<h3>What is a regression line?</h3>
A regression line displays the connection between scattered data points in any set. It shows the relation between the dependent y variable and independent x variables when there is a linear pattern.
According to the given problem,
From the table we can see,
ln(Element) is the dependent variable and Time is the independent variable.
The constant = 2.305,
Time = -0.101
Hence, we can conclude, our least squared regression line will be
In (Element) = 2.305 - 0.101 (Time).
