The lifetime, in years, of a certain type of pump is a random variable with probability density function what is the probability that a pump lasts more than two years? what is the probability that a pump lasts between two and four years? find the mean lifetime. find the variance of the lifetimes. find the cumulative distribution function of the lifetime. find the median lifetime. find the 60th percentile of the lifetimes.

d. is the correct answer

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
