Answer:
The impedance of the circuit = 12500 Ω
Explanation:
<em>Impedance:</em> This is the overall opposition to the flow of current in an a.c circuit by any two or all of the three circuit elements.(R, L, C) is called <em>impedance.</em>
<em>The S.I unit of Impedance is Ohms. (Ω), It can be represented mathematically as</em>
Z = √(Xc² + R²).................... Equation 1
Where Z = impedance, Xc = reactance of the capacitor, R = resistance of the resistor.
<em>Given: Xc = 7500 Ω, R = 10000 Ω</em>
<em>Substituting these values into equation 1,</em>
<em>Z = √(7500² + 10000²)</em>
<em>Z = √(56250000 + 100000000)</em>
<em>Z = √(156250000)</em>
Z =12500 Ω
Therefore, The impedance of the circuit = 12500 Ω

Explanation:
measurement of a set, accuracy is closeness of the measurements to a specific value, while precision is the closeness of the measurements to each other.
Accuracy has two definitions:
More commonly, it is a description of systematic errors, a measure of statistical bias; low accuracy causes a difference between a result and a "true" value. ISO calls this trueness.
Alternatively, ISO defines[1] accuracy as describing a combination of both types of observational error above (random and systematic), so high accuracy requires both high precision and high trueness.
Precision is a description of random errors, a measure of statistical variability.
In simpler terms, given a set of data points from repeated measurements of the same quantity, the set can be said to be accurate if their average is close to the true value of the quantity being measured, while the set can be said to be precise if the values are close to each other. In the first, more common definition of "accuracy" above, the two concepts are independent of each other, so a particular set of data can be said to be either accurate, or precise, or both, or neither.
Answer: The speed limit is 15 mph when you come within 100 feet of a railroad crossing and you cannot see the tracks for 400 feet in both directions. You may go faster than 15 mph if the crossing is controlled by gates, a warning signal, or a flagman.
