Answer:
Measurement error.
Step-by-step explanation:
Measurement Error are the error when there is difference found in true value of data and measured quantity of data. This difference could be found if we are missing some data in the sample.
The error could be reduced by carefully designing the process of data collection and it´s measurement.
Measurement error are classified into two type of error:
- Random error.
- Systematic error.
We have to determine the conversion factor used to convert inches to yards. Yard and inch are US and British customary length units. We know that 1 yard = 3 feet = 36 inches. So we just have to divide 1 by 36. 1 : 36 = 0.027777.... ( more accurate with more decimal digits ). For example: 54 yards = 54 * 0.0277777 = 1.4999958 ( approx. 1.5 ).

Answer: The value of k for which one root of the quadratic equation kx2 - 14x + 8 = 0 is six times the other is k = 3.
Let's look into the solution step by step.
Explanation:
Given: A quadratic equation, kx2 - 14x + 8 = 0
Let the two zeros of the equation be α and β.
According to the given question, if one of the roots is α the other root will be 6α.
Thus, β = 6α
Hence, the two zeros are α and 6α.
We know that for a given quadratic equation ax2 + bx + c = 0
The sum of the zeros is expressed as,
α + β = - b / a
The product of the zeros is expressed as,
αβ = c / a
For the given quadratic equation kx2 - 14x + 8 = 0,
a = k, b = -14, c = 8
The sum of the zeros is:
α + 6α = 14 / k [Since the two zeros are α and 6α]
⇒ 7α = 14 / k
⇒ α = 2 / k --------------- (1)
The product of the zeros is:
⇒ α × 6α = 8 / k [Since the two zeros are α and 6α]
⇒ 6α 2 = 8 / k
⇒ 6 (2 / k)2 = 8 / k [From (1)]
⇒ 6 × (4 / k) = 8
⇒ k = 24 / 8
⇒ k = 3
