Show that ¬P → (Q → R) and Q→(P∨R) are logically equivalent.
What is the axis of symmetry for the graph of y=2x2-4x+2
A real function f defined on an interval [a,b] with a<c<b where c is a point of the interval, is said to be differentiable at the point x=c if
Applying Cauchy’s mean value theorem to the function f and g defined as f(x)=x2 and g(x)=x for all x∈[a,b], gives
Verify that this [P(x)] is a probability distribution
Consider a population consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Suppose samples of size 2 are drawn from this
population without repetition. Describe the sampling distribution of the sample means. What is the mean and
variance of the sampling distribution of the sample means? Compare these values to the mean and variance of
the population.
In a case of 24 plates, 3 of the plates have defects. The first plate taken from the case is defective and not returned to the case. What is the probability that the next plate sold is not defective?
two cars each moving at constant speed on a straight road pass a certain point on the road at the same time if car A is moving at 23 m/s and car B is moving at 14 m/s how far apart will they be after five minutes if they contains at the same speed?
A tortoise moves at 0.5 m/s and hare moves at 6m/s if they decided to have a race over a straight 500m course how far be lined the hare will the tortoise be when the hare crosses the finish line?
