2. This week, we studied the test score Y versus number of hours, X, spent on test preparation, of a student in a French class of 10 students with the collected results shown below Number of hours studied Test score 31 10 14 73 37 12 60 91 21 84 17 (a) Use linear normal regression analysis method or the least-squares approximation method to predict the average test score of a student who studied 12 hours for the test (b)...
Consider the following problem: Section II Con n a truth function f, find a statement S, only intolring the connecti e, ^,V and whose trva function is j. (a) Exhibit an algorithm that solves this problem. (b) Applied the exhibited algorithm to the truth function, 1 given by: TITIT (c) Suppose that the truth function f has n arguments represented by the variables i Consider the first algorithm studied in class to solve the problem of item (a). Let 01,92,.......
3. This problem is to prove the following in the precise fashion described in class: Let o sR be open and let f :o, R have continuous partial derivatives of order three. If (o, 3o) ▽f(zo. ) = (0,0),Jar( , ) < 0, and fzz(z ,m)f (zo,yo) -(fe (a ,yo)) a local maximum value at (zo, yo) (that is, there exists r 0 such that B,(zo, yo) S O and f(a, y) 3 f(zo, yo) for all (x, y) e...
This problem is from topology class.
Thank you for the help!

Problem! 3. I et X be a randoln variable with the prnf /'s and Y = g X be another randoln variable Recall that Ely] is defined to be Σ6b/h(b), where /y is the prnf of Y . In this question we will verify this intitive statement: E[Y] = Σ"g(a) PX (a) i.e. we dont need to compute the pf of Y to compute EY (a) First consider the example where X is uniformly distributed in -5, -4... 4,5) (i)...

3. This problem is to prove the foll owing in the precise fashion described in class: Let O R2 eopen and let/ : O → R have continuous partial derivatives of order three. If (zo,to) e o, )(0,0), fxr(ro, vo) < 0, and frr(ro, o)(ro, o)- ay(ro, Vo) 0, then f achieves a local maximum value at (zo. 5o) (that is, there exists 0 such that Br(o, vo) S O and (x, y) S f(xo, so) for all (x, y)...
PLEASE PLEASE PLEASE ANSWER THIS! ONLY THIS INFORMATION

Problem 7. A test contains n = 3 true or false questions. Any given student answers each question correctly with a certain probability called the "success rate"), independently acorss questions. In the class, 80% of the students know the materials quite well and have a success rate of p1 = 0.9, so the number of correct answers they get follows Bn, Pı). The rest of the students do not know...
Let ????(?, ?, ?) be a predicate that
represents the statement “? makes a fool of ? on day ?.” Thus, for
example, ∃?: ∀?: ????(?, ???, ?) means that there is someone who
fools Lem every day.
Problem 4. (5 points) Using the definition above, determine if there a difference between the following statements. If so, explain the difference in one or two sentences. VxVy: Fool(Sam, x, y) vs. VyVx: Fool(Sam, x, y) b. 3x3y: Fool(Sam, x,y) vs. 3y3x:...
