Consider an MNC that is exposed to the Taiwan dollar (TWD) and the Egyptian pound (EGP). 25% of the MNC's funds are Taiwan dollars and 75% are pounds. The standard deviation of exchange movements is 7% for Taiwan dollars and 5% for pounds. The correlation coefficient between movements in the value of the Taiwan dollar and the pound is .7. Based on this information, the standard deviation of this two-currency portfolio is approximately: Group of answer choices 2.63% 5.12% 11.50% 4.33%

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

Drag each expression to the correct location on the solution. not all expressions will be used. consider the polynomial 8x + 2x2 - 20x - 5. factor by grouping to write the polynomial in factored form.
