(3 marks) (ii) Less than 40? (3 marks) (b) In a sample of 100 students, how many would you expect to have a score between 50 and 65? (4 marks) Parallelograms and ProofsQuestion 7 of 10Which of the following are necessary when proving that the opposite anglesof a parallelogram are congruent? Check all that apply.A. Opposite sides are perpendicular.B. Opposite sides are congruent.C. Corresponding parts of similar triangles are similar.D.

In order to find the optimum detection threshold equation (5.80) is dderived with respect to y, set to zero and solved for y. Using Leibniz's differentiation rule and some algebra it can be shown that on Po $1 + $0 = Yopt log + (5.81) - $180 P1 2 When is profit maximized for a firm that has a monopoly? a. Where total cost is minimum. b. Where the difference between total revenue and total cost is maximum. c. At break-even output. which type of decision is deciding whether to introduce a new product line? according to economists, an efficient tax is one that . 3x2y + (1 - 4xy) dy =0 2. 1 + xy +y + xy = 0 3. (x+y)y - y = x 4. (x+44) dy = xy aux 5. y' + 2y = xy. Which utility do you use to set up loopback policies?
