A sketch of the normal distribution is shown in the figure below.
The mean is μ, and the curve is symmetric about the mean.
The total area under the curve is 1.
The standard deviation is σ.
The interval (μ-σ, μ+σ) contains approximately 68% of the total area.
The interval (μ-2σ, μ+2σ) contains approximately 95% of the total area.
Answer: 95%

Answer:
m∠OPQ + (2x+16)° = 180°
Step-by-step explanation:
You need to know a couple of things about quadrilaterals.
- The sum of the internal angles is 360°
- Opposite angles of an inscribed quadrilateral total 180°.
An inscribed quadrilateral is one that has its vertices on a circle, as in the given figure.

To actually solve the figure (find the measures of the angles), a two-step process is involved. First, you must find the value of x. You do that by making use of the fact that angles O and Q total 180°.
After you know the value of x, you can figure the measure of angle R, and make use of the fact that angles R and P total 180°.
__
Here, you're not asked to solve the figure. Instead, you're asked how you might find angle P. You do that as described in the previous paragraph:
m∠OPQ + m∠ORQ = 180° . . . . . . . angles R and P total 180°
m∠OPQ + (2x+16)° = 180° . . . . . . . substitute (2x+16)° for m∠ORQ
This matches the first answer choice.
