Answer:

Option A, 70

Step-by-step explanation:

Step 1: Find the Science grade

(95 + 85 + 90 + 80 + x) / 5 = 84

Step 2: Multiply both sides by 5

(95 + 85 + 90 + 80 + x) / 5 * 5 = 84 * 5

95 + 85 + 90 + 80 + x = 420

Step 3: Combine all of the numbers

95 + 85 + 90 + 80 + x = 420

350 + x = 420

Step 4: Subtract 350 from both sides

350 + x - 350 = 420 - 350

x = 70

What is 1 standard deviation on a

PilotLPTM [1.2K]

Answer:

D. The distance from the mean to an inflection point

Step-by-step explanation:

We rarely encounter the actual formula for the normal PDF. It is ...

$p(x)=\dfrac{1}{\sqrt{2\pi}}e^{-\dfrac{x^2}{2}}$

In fact, the inflection points are at x = ±1, where the curve changes from being concave downward to concave upward.

So, one standard deviation is the distance from the mean to an inflection point.
