Is it true that using two methods answer will varies? Use Bernoulli in the first method. Show the complete solution

How would i solve this problem for linear alge

A meteorologist claims that the average high temperature for the month of August in Chicago, Illinois is 83 degrees. If the residents of Chicago do not believe this to be true. what hypothesis should they test? Let mu be the average high temperature for the month of August in Chicago. Group of answer choices H0: mu = 83 versus Ha: mu < 83 H0: mu = 83 versus Ha: mu > 83 H0: mu = 83 versus Ha: mu is not equal to 83

can you please reply quicklyIn which option is the solution of LGS with Gaussian elimination method given correctly?(First photo is LDS elimination, second photo is options)

In North America, between 100 million and 1 billion birds die each year by crashing into windows on buildings, more than any other human-related cause. This figure represents up to 5% of all birds in the area. One possible solution is to construct windows angled downward slightly so that they reflect the ground rather than an image of the sky to a flying bird. An experiment by Klem et al. (2004) compared the number of birds that died as a result of vertical windows, windows angled 20 degrees off vertical, and windows angled 40 degrees off vertical. The angles were randomly assigned with equal probability to six windows and changed daily; assume for this exercise that windows and window locations were identical in every respect except angle. Over the course of the experiment, 30 birds were killed by windows in the vertical orientation, 15 were killed by windows set at 20 degrees off vertical, and 8 were killed by windows set at 40 degrees off vertical.  a. Clearly state an appropriate…

In an optical fibre, the power drops by a factor of 10 approximately every 30 km. If the transmit power is 0.35 W, how far will a signal be transmitted before the power is attenuated to 350 μW? As part of your answer, include a table showing the signal power (in W) vs. distance in 30 km intervals (like Table 1.2 in Section 1.4.4). If a high-quality coaxial cable (LDF5-50A) operating at 200 Mbps is used instead of an optical fibre, how would you expect the calculated distance value to change? Briefly explain your answer (see Section 1.4.4). You are not required to include another table.

What does Euler’s Method allow you to do?

A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degrees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored.  What is a strong counterarguement?  A. Even 0.08 degrees is a lot and thus should be considered. B. The margin of error is just extra information and thus can be ignored. C. The difference with any previous decade is much greater than the margin of error. D. 0.15 - 0.08 is 0.07, which is still an increase and thus should be considered.
