Please don't provide handwrittin solution..... Consider the following critical values: to.1, 35= 1.306; to.05, 35= 1.690, to.025, 35 = 2.030 inanswering this question: To assess the average survival time of our LED lights in extremecold,we randomly sample 36. They have an average survival time of 42.4 days with a samplestandard deviation of 8.8 days. Based on this sample, we conduct an appropriate 1-sidedhypothesis test to determine if the population mean survival time of our LEDs is greater than37 days. The p-value for this test is:A.B.C.D.Greater than 0.1.Between 0.05 and 0.1.Between 0.025 and 0.05.Less than 0.025.

2. Jimmy was drawing rectangles at his desk. After a while he concluded that if you increased one of the sides by 10% and decrease the other side by 10% the area won't change. Is Jimmy correct? Provide a formal mathematical argument as well as a "teacher response" to Jimmy.
i will appreciate if you help me solve this in easy way as possible
Two ecotaxis companies A and B handle different rates. Company A has a rate of $ 8.5, the cost of the flag is $ 4.6 the cost per kilometer traveled. Company B charges $ 6.75 for the flag and $ 5.2 for the cost of each kilometer traveled. Decide which two of the following statements are valid for this situation a) The cost of both companies coincides at 35/12 km b) The cost of the trip with company B is cheaper than company A regardless of the distance traveled c) With a cost of 30 pesos you can go further with company A

A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race. Preview Solve f(t) = 0 and describe what your solution represents. t = Preview…
It's true sand dunes in Colorado rival sand dunes of the Great Sahara Desert! The highest dunes at Great Sand Dunes National Monument can exceed the highest dunes in the Great - Sahara, extending over 700 feet in height. However, like all sand dunes, they tend to move around in the wind. This can cause a bit of trouble for temporary structures located near the "escaping" dunes. Roads, parking lots, campgrounds, small buildings, trees, and other vegetation are destroyed when a sand dune moves in and takes over. Such dunes are called "escape dunes" in the sense that they move out of the main body of sand dunes and, by the force of nature (prevailing winds), take over whatever space they choose to occupy. In most cases, dune movement does not occur quickly. An escape dune can take years to relocate itself. Just how fast does an escape dune move? Let x be a random variable representing movement (in feet per year) of such sand dunes (measured from the crest of the dune). Let us assume that…
That is what I got but the platform we are using says the answer is incorrect. Thank you so much though!!
