Suppоse I wish tо determine the distаnce tо Sаturn. From Los Angeles, I meаsure the separation of Saturn from 12 Aquilae (a star in constellation Aquila) to be 20o 53' 38". You are at the equator (same longitude), and at the same time measure the separation between Saturn and 12 Aquilae to be 20o 53' 31". The distance between Los Angeles and the equator is 3732.95 km. According to these numbers, how far away is Saturn?

An оriginаl mаcаrоni and cheese recipe calls fоr 2½ cups grated cheddar cheese. Marcus decides to make the recipe healthier by using 1½ cups grated cheese and 1 cup fat-free Greek yogurt; he is curious if the modified recipe will result in a dish of macaroni and cheese that looks, smells, and tastes as good as a serving from the original recipe. Marcus completes a batch of each recipe on Tuesday and his test panel arrives at 1:30 (about 30 minutes after both dishes were pulled from the oven). The panel is made up of three friends who know nothing about the experiment other than they will be tasting a food product. Marcus gave panel members no instructions other than to show up at his place at 1:30. When the doorbell rings, one friend take the last bites from a bag of chips and asks Marcus if he can toss the empty bag in his kitchen trash can. Marcus takes the bag so the friend will not see any of the ingredients used to make the mac and cheese dishes. Marcus sits the friends around his dining room table and asks them not to discuss the food samples or use any sounds or body language to express their like or dislike of the products. He then gives them a score card, asks each of them to eat a 1-cup serving of each recipe, and complete the survey card where they respond to questions about the look, smell and taste of each recipe. When the friends are done, Marcus thanks them, gives them each of bottle of water and they leave. Address the following:a. What is the purpose of the study?b. Clearly identify the independent and dependent variables. c. Discuss any extraneous variables that may influence the results.d. How could the experiment be improved?e. What would be a good title for this experiment?
