The problem ask to explain the use if the normal curve to compare that
score to the population and the best explanation is that the normal
curve depends on a lot of assumptions. If the population score are
normally distributed, we will know its mean and standard deviation, so
can tell that our particular individual's row score falls on that
distributions.

The formula is
is over of = what the percent is over 100
Angle CP = 45 degrees, because it's bisecting a right angle (90 degrees) and half of 90 degrees is 45.
The first derivative of the function f(x) = x² - 5 is equal to f'(x) = 2 · x.
<h3>How to find the derivative of a quadratic equation by definition of derivative</h3>
In this question we have a quadratic function, in which we must make use of the definition of derivative to find the expression of its first derivative. Then, the procedure is shown below:
f(x) = x² - 5 Given
f' = [(x + h)² - 5 - x² + 5] / h Definition of derivative
(x² + 2 · x · h + h² - 5 - x² + 5) / h Perfect square trinomial
(2 · x · h + h²) / h Associative, commutative and modulative properties / Existence of additive inverse
2 · x + h Distributive, commutative and associative properties / Definition of division / Existence of multiplicative inverse
2 · x h = 0 / Result
The first derivative of the function f(x) = x² - 5 is equal to f'(x) = 2 · x.
