The peak temperature t, in degrees fahrenheit, on a july day in antarctica is a gaussian rv with a variance of 256. t exceeds 15°f with the probability of ½. a. plot the pdf for t, �7(�), using the matlab. (see provided in hw4) b. what is p[t > 32], the probability the temperature is above freezing? c. what is p[t < 0]? d. what is p[t > 50]?

Ineed to know the answer right now! !

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3
