Use the predicate specifications(x, y): x beats yF (x): x is an (American) football teamQ(x, y): x is quarterback of yL(x,y): x
attashe74 [19]

Answer:

a) ∀y∃x(Q(x, y))

b) (B(Jayhawks, W ildcats)→¬∀y(L(Jayhawks, y)))

c) ∃x(B(Wildcats, x) ∧ B(x, Jayhawks))

Explanation:

a) The statement can be rewritten as "For all football teams, there exists a quarterback" which is written in logical symbols.

b) The statement is an implication and thus have a premise and a conclusion. The premise states "Jayhawks beat the Wildcats" which is translated using B(x, y). The conclusion can be rewritten as "It is not the case that Jayhawks lose to all football teams".

c) The statement is a simple conjunction which can be written as "There exists a team x such that the Wildcats beats x and x beats Jayhawks"

When a process is in a state of statistical control, all of the points on a control chart should fall within the control limits.
Mars2501 [29]

it is undesirable that all of the points should fall extremely near, or exactly on, the centerline of the control chart Because:

  • It can make it difficult  to interpret patterns and draw conclusions in a run chart.
  • It can lead hinder the process, and make it unstable.
<h3>When a data point falls outside the control limits of a run chart ?</h3>

If a data point falls is said to outside the control limits, we can say that the process is said to be out of one's control and it is good that an investigation is done to ascertain and remove the cause or causes.

So, it is undesirable that all of the points should fall extremely near, or exactly on, the centerline of the control chart Because:

  • It can make it difficult  to interpret patterns and draw conclusions in a run chart.
  • It can lead hinder the process, and make it unstable.

What does a peak flow meter allow you to assess?
Alex Ar [27]

Answer:

  peak flow and any engineering considerations related thereto

Explanation:

It should be no surprise that a peak flow meter will report peak flow, sometimes with important maximum-value, time-constant, or bandwidth limitations. There are many engineering issues related to flow rates. A peak flow meter can allow you to assess those issues with respect to the flows actually encountered.

Peak flow can allow you to assess adequacy of flow and whether there may be blockages or impediments to flow that reduce peak levels below expected values. An appropriate peak flow meter can help you assess the length of time that peak flow can be maintained, and whether that delivers sufficient volume.

It can also allow you to assess whether appropriate accommodation is made for unexpectedly high flow rates. (Are buffers or overflow tanks of sufficient size? Is there adequate protection against possible erosion? Is there adequate support where flow changes direction?)

The temperature at which all molecular motion stops is known as: a) Absolute temperature b) molecular temperature c) absolute ze
Naya [18.7K]

Answer:

c) absolute zero

Explanation:

The fourth principle of thermodynamics posed by the Romanian economist Nicholas Georgescu-Roegen, explains the presence of absolute zero is said that at this temperature the internal molecular movement becomes zero making the internal energy (U) zero, absolute zero is equivalent to -273.15C or 0Kelvin
