For the vector of daily temperatures [T1 ··· T31] and average temperature Y modeled in Quiz 5.8, we wish to estimate the probability of the event.
To form an estimate of A, generate 10,000 independent samples of the vector T and calculate the relative frequency of A in those trials.
Quiz 5.8
The daily noon temperature in New Jersey in July can be modeled as a Gaussian random vector T = [T1··· T31] where Ti is the temperature on the ith day of the month. Suppose that E[Ti] = 80 for all i, and that Ti and Tj have covariance
Define the daily average temperature as
Based on this model, write a program p=julytemps(T) that calculates P[Y ≥ T ], the probability that the daily average temperature is at least T degrees.

A 230-V DC shunt motor, with an armature resistance of 0.4 Ω and a ?eld resistance of 200 Ω, absorbs 2.5 A in no-load operation. In another loading condition, the same motor runs at 300 rpm while absorbing 30 A. Calculate the no-load speed.
