.
The <em>b</em> value in this case is <em>c</em>, and it will always equal the square of half of the <em>b</em> value.
- Perfect square trinomial:

- or

<h2>Solving the Question</h2>
We're given:
In a trinomial, we're given the
and
values. <em>a</em> in this case is 1 and <em>b</em> in this case is 4. To find the third value by dividing 4 by 2 and squaring the quotient:
Therefore, the term that we can add is + 4.

To write this as the square of a bracketed expression, we can follow the rule
:

<h2>Answer</h2>


Answer:
The distribution of all values of <em>X</em> is the sampling distribution of <em>X</em>.
Step-by-step explanation:
The sampling distribution of a statistic is the probability distribution computed through a large number of samples taken from a specific population.
For example, the sampling distribution of mean is the probability distribution of sample mean, were the sample means are computed from various samples taken from a specific population.
In this case a class of 35 students is divided into samples of 7.
Each sample is considered and the heights of the 7 students are noted.
The random variable <em>X</em> is defined as the tallest height.
The distribution of all values of <em>X</em> is the sampling distribution of <em>X</em>.
