Answer:
c = 169
Step-by-step explanation:
Given
m² - 26m
To complete the square
add ( half the coefficient of the m- term)² to m² - 26m
m² + 2(- 13)m + (- 13)²
= m² - 26m + 169 ( with c = 169 )
= (m - 13)² ← perfect square

Step-by-step explanation:
Let <em>X</em> denote the score.
It is provided that X follows a normal distribution with mean 110 and standard deviation 15.
A students score, <em>x</em> = 95.
Compute the probability of scores that should fall between the student's score and the mean as follows:
Thus, 34% of scores should fall between your score and the mean.
