Covariance matrix of temperature measurements in a weather station, represented with a random vector x=[x1 x2 x3]’, is given as: it is known that rvs xi are random gaussian in nature �" = 8 14 12.1 10.8 12.1 12 11.4 10.8 11.4 11 > a. what is the variance in these three measurements? b. what are the cov[x1,x2] and cov[x3,x1]? c. are xi independent from one another?

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
