Step 1
(i)
Let,
p:Karen is studying computing.
q:Ketsi is studying mathematics.
q:Ketsi is now studying mathematics.
Then,(p!q)q:Either Karen is studying computing and Ketsi is not mathematics, or Ketsi is studying mathematics.
Here, principal connective is "vv"(i.e."or").
Step 2
(ii)
Let,
p: It is sunny.
q: I will carry an umberella.
Then, !(pq): It is not the case that if it is sunny then i will carry an umbrella.
Here, principal connective is ""(i.e."not").

Young’s modulus is a quantitative measure of stiffness of an elastic material. Suppose that for aluminum alloy sheets of a particular type, its mean value and standard deviation are 70 GPa and 1.6 GPa, respectively (values given in the article “Influence of Material Properties Variability on Springback and Thinning in Sheet Stamping Processes: A Stochastic Analysis” (Intl. J. of Advanced Manuf. Tech., 2010: 117–134)). If X¯ is the sample mean Young’s modulus for a random sample of n = 16 sheets, where is the sampling distribution of X¯ centered, and what is the standard deviation of the X¯ distribution?

Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma. Over a period of months, an adult male patient has taken eight blood tests for uric acid. The mean concentration was x¯=5.35mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal with σ=1.85mg/dlσ=1.85mg/dl. What conditions are necessary for your calculations?

A car travels at 108 kph from A to B for t seconds, applies the brakes for 4 seconds between B and C to give the car a constant deceleration and a speed of 72 kph at C, and finally travels at this speed from C to D, also for t seconds. If the total horizontal distance from A to D is 3100 m, determine the distance between A and B.
