A certain game involves tossing 3 fair coins, and it pays 26¢ for 3 heads, 10¢ for 2 heads, and 1¢ for 1 head. Is 10¢ a fair price to pay to play this game? That is, does the 10¢ cost to play make the game fair? The 10¢ cost to play a fair price to pay because the expected winnings are ¢. (Type an integer or a fraction. Simplify your answer.)

Exercise 10-1 (Algo) Direct Materials Variances [LO10-1] Bandar Industries manufactures sporting equipment. One of the company's products is a football helmet that requires special plastic. During the quarter ending June 30, the company manufactured 3,600 helmets, using 2,592 kilograms of plastic. The plastic cost the company $19,699. According to the standard cost card, each helmet should require 0.63 kilograms of plastic, at a cost of $8.00 per kilogram. Required: 1. What is the standard quantity of kilograms of plastic (SQ) that is allowed to make 3,600 helmets? 2. What is the standard materials cost allowed (SQ \times SP) to make 3,600 helmets? 3. What is the materials spending variance? 4. What is the materials price variance and the materials quantity variance? (For requirements 3 and 4, indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values. Do not round intermediate calculations.) 1. Standard quantity of kilograms allowed 2. Standard cost allowed for actual output 3. Materials spending variance 4. Materials price variance 4. Materials quantity variance

3. Determine the polarization of each of the plane-waves whose electric field is given by the following expressions. (The answer must be supported by the required conditions. Also, indicate right-hand or left-hand when applicable.) (a) \(\vec{E}_1 = 20(j\hat{a}_x + \hat{a}_y)e^{-j30z} \) V/m, (b) \(\vec{E}_2 = 10(3\hat{a}_x + j2\hat{a}_y)e^{-j20z} \) V/m, (c) \(\vec{E}_3 = 30[(1-j)\hat{a}_x + (1+j)\hat{a}_y]e^{-j10z} \) V/m.

The image below shows the average altitude of the International Space Station in 2020. Posigrade burns are done to avoid orbital debris and as a result of orbit decay (decay rate varies with solar cycle), or to accommodate vehicle docking phase angle requirements. Retrograde burns may also be done to accommodate the phase angle requirement for docking vehicles - may have been the case for the April and early July orbit adjustments - or when the orbit is too high. A lower orbit is better for crew radiation protection and for better orbital debris protection (debris in lower orbits encounter more drag and decays faster to burn up in the atmosphere). The max altitudes in this table are all less than the upper limit of 460 km altitude. Referencing the diagram, consider the burn in mid-April to transition from the initial higher orbit to the lower orbit. Assume the initial orbit is circular and estimate altitude from the image. Assume the lower orbit is elliptical after a single burn, with the initial altitude as it's apogee. Estimate the final average orbit from the image. Calculate the required delta V. Include a sketch with the intial and final orbits; identify and label the burn location.
