Capacitance values between Class Frequency (µF) 94-95.9 7 96-97.9 19 98-99.9 35 100-101.9 31 102-103.9 23 104-105.9 5 b) The company automatically manufacture its control boards. The quality inspector has determined that in each package, 89% of the control boards are within the correct tolerance values with respect to their functionality, the remainder were out of tolerance. If a random sample of 6 boards are drawn from the package determine the probabilities that: i) ii) ii) 3 of the sample boards are out of tolerance More than 3 of the sample boards are out of tolerance Less than three of the sample boards are out of tolerance. c) A batch of 2450 transformers from the production line have a mean output voltage of 215.3 V and the Standard deviation of the output voltage is 2.8 V. If the voltages of the transformers in the box are assumed to be normally distributed, determine the following: i) ii) iii) The number of Transformers with output voltages greater than 216.9 V. The number of Transformers with output voltages less than 213.1 V, The number of Transformers with output voltages between 214 V and 216 V. For this problem you should use the table of z-values shown in Figure 1. All the calculations must be clearly explained with suitable diagrams where appropriate to aid understanding to a non-technical audience. d) A batch of transformers produced by a different production line in a factory have a mean output voltages of 225 V and a standard deviation of 2.4 V. The production manager suspects that the Production line is producing too many out of voltage components and should be stopped and serviced. If the quality inspector takes a random sample of 35 transformers from the batch and finds that the mean output voltage of the sample is 225.6 V. Using a level of confidence of 0.05, determine
Family of Curves
A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These families appear commonly in the solution of differential equations. When a constant of integration is added, it is normally modified algebraically until it no longer replicates a plain linear transformation. The order of a differential equation depends on how many uncertain variables appear in the corresponding curve. The order of the differential equation acquired is two if two unknown variables exist in an equation belonging to this family.
XZ Plane
In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are real numbers and a is the horizontal coordinate and b is the vertical coordinate. This type of plane is called two-dimensional and it contains two perpendicular axes, the horizontal axis, and the vertical axis.
Euclidean Geometry
Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) geometry was introduced by the Greek mathematician Euclid, and that is why it is called Euclidean geometry. Euclid explained this in his book named 'elements'. Euclid's method in Euclidean geometry involves handling a small group of innately captivate axioms and incorporating many of these other propositions. The elements written by Euclid are the fundamentals for the study of geometry from a modern mathematical perspective. Elements comprise Euclidean theories, postulates, axioms, construction, and mathematical proofs of propositions.
Lines and Angles
In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
