Gcamera measurement. the measurement from a camera can be expressed as y = ax + z, where x is the object position with mean µ and variance σ 2 x, a is the occlusion indicator function and is equal to 1 (if the camera can see the object) with probability p, and 0 (if the camera cannot see the object) with probability (1 − p), and z is the measurement error with mean 0 and variance σ 2 z . assume that x, a, and z are independent. find the best linear mse estimate of x given the camera measurement y . your answer should be in terms of only µ, σ 2 x, σ 2 z , and p.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
