The answer is z score of 2.00 is most desirable because it is 2.00 standard deviations beyond the mean and would agree to the highest of the five diverse likely test scores. In addition, the number of standard deviations that a given value x is above or below the mean is the z score or as called as standardized value. The negative z score agrees to an x value less than the mean while a positive z score agrees to an x value larger than the mean. The more negative the z score the more the x value is under the mean and the further positive the z score the more the x value is below the mean.
All the possible values of z can be found using (D) (5z)² = (5 + z)².

What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
- A mathematical statement made up of two expressions joined by an equal sign is known as an equation.
- 3x - 5 = 16 is an example of an equation.
- We get the value of the variable x as x = 7 after solving this equation.
To find the following equations could be used to find all possible values of z:
- The product of z and 5 = 5z
- Sum of z and 5 = (5 + z)
- Squaring the product of z and 5 gives the same result as squaring the sum of z and 5.
- We can express the above statement as:
- Squaring 5z gives squaring (5 + z)
- So, (5z)² = (5 + z)²
Therefore, all the possible values of z can be found using (D) (5z)² = (5 + z)².
