Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
![### Probability Calculation for Normally Distributed Data
**Question:**
Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading less than -0.749°C.
**Solution:**
\[ P(Z < -0.749) = \]
**Instructions:**
1. Convert the thermometer reading to a Z-score using the formula for a standard normal distribution.
2. Use the standard normal distribution table or a calculator to find the probability corresponding to the Z-score.
**Interactive Element:**

#### Explanation:
- **Mean (µ):** 0°C
- **Standard deviation (σ):** 1.00°C
- **Desired reading (X):** less than -0.749°C
Use the Z-score formula:
\[ Z = \frac{X - \mu}{σ} \]
\[ Z = \frac{-0.749 - 0}{1.00} \]
\[ Z = -0.749 \]
Now, look up the Z-score of -0.749 in the standard normal distribution table or use a calculator to find the probability \( P(Z < -0.749) \).
Once you find the probability, input the value in the provided box and submit your answer.
**Tools/Resources:**
- Z-score table
- Online normal distribution calculator
**Conclusion:**
This statistical problem involves understanding and using concepts of normal distribution, mean, and standard deviation to find the probability for a given reading.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3e82b789-902b-4bed-91c7-23ced64abede%2Fd9b9bd42-e1ba-49ab-a4d0-2cd6916832a9%2F5xnab9_processed.jpeg&w=3840&q=75)
