We already know how the trigonometric ratios are related to the opposite, adjacent, and hypotenuse sides of a triangle. And now we know how the opposite, adjacent, and hypotenuse sides are related to x,y, and r. So we can tie it all together:TextbooksLeaderboardsCampaignsLearner opportunitiesPricingSupportKutlwano TemaNOTE: In the diagram above, the point (x;y) does not have to be in Quadrant I. It will move around the circle depending on the value of θ. When the point rotates around the circle, the triangle will change shape and the values of x and y will change. But the relationships above stay the same.The definition of the cosine ratio on the Cartesian plane is rx.NotificationsSubmit your answer as: □□Log out Get tutor helpSarah and David agree to a friendly game of darts. Sarah has some skill as a carpenter and makes a fancy dartboard, as show below:Each of the green and yellow squares is 4 cm×4 cm. The pink, dark blue, and light blue circles are exactly in the centre of the dartboard and have radii of 1 cm,3 cm and 5 cm respectively. When you include the grey teardrops in each corner, the whole dartboard is 32 cm across.As inquisitive mathematicians, they are of course interested in the probabilities of certain outcomes, ie what is her chance of landing the dart in a yellow section, etc. They haven't had much practice with playing darts, and 10% of the time they don't hit the dartboard at all (ie they only hit it 90% of the time). Of the shots that land on the dartboard, they are randomly distributed except that 70% land within the region containing the red square and the centre circles, and 40% land within the region containing the centre circles.In deciding on a fair scoring system for this dartboard, they agree that the points awarded for hitting a certain colour should be inversely proportional to the chance of hitting that colour (ie: something twice as rare should be worth twice as much). As a starting point, they decide that striking yellow should be worth 8 points.Your task is to find the probability distribution of hitting each colour, and thus determine how many points each colour is worth. The game is not played with half-points, so if the correct proportional answer is not a whole number, round it to the nearest whole number.For full marks your answers must include:- an introductory explanation of your overall strategy- full details including brief explanations of all calculations used- tables where appropriate to summarise your results (these may include relevant calculations) Get tutor helpwww-awu.aleks.com/alekscgi/x/IsL.exe/10_u-IgNsIkr7j8P3jH-lv-HqvUw8xPuAcyASWGH_ApjAQHcF25VHHv5gUefcCS Web ApplicationsFree email account.Snow LeopardsClever | PortalEpic Games Store|-.NetfixMotion SongsData Analysis and ProbablitlyProbability Involving one dle or choosing from n distinct objectsA box contains ten cards labeled Q,R,S,T,U,V,W,X,Y, and Z.
