Use R to answer the following questions: This problem will use R to find all possible orderings of 7 objects and probabilities associated with them. Consider your vector of possible values to be: values = as.character(1:7) (a) Use the function sample to draw from values 7 times (without replacement), and return this vector. Notice it is a vector, with 7 values. Display your particular draw. (b) Repeat (a) 100000 times using an sapply. Notice the result has 7 rows, and...

Consider the following (true) statement: “All birds have wings but some birds cannot fly.” Part 1 Write this statement symbolically as a conjunction of two sub-statements, one of which is a conditional and the other is the negation of a conditional. Use three components (p, q, and r) and explicitly state what these components correspond to in the original statement. Hint: Any statement in the form "some X cannot Y" can be rewritten equivalently as “not all X can Y,”...

Two charged objects 1 and 2 are held at a distance r apart. Object 1 has mass m and charge +3q, and object 2 has mass 2m and charge +q. The objects are released from rest. Assume that the only force exerted on either object is the electric force exerted by the other object. Part B When the objects are at a distance 4r apart, what is the speed of object 1? Part C When the objects are at a...

The writing on the passenger-side mirror of your car says "Warning! Objects in mirror are closer than they appear" (Figure 1). There is no such warning on the driver's mirror. Consider a typical convex passenger-side mirror with a focal length of -80 cm. A 1.6-m-tall cyclist on a bicycle is 25 m from the mirror. You are 1.0 m from the mirror, and suppose, for simplicity, that the mirror, you, and the cyclist all lie along a line.Part A How...
