Two sport utility vehicles (SUVs) are being considered by a recent engineering graduate. Using the following data evaluate which sport utility vehicle is better. Use six attributes in your a point, overall appearance, comfort, safety, reliability, and fuel mileage. Larger scores on overall appearance, comfort, safety, reliability, and fuel mileage are preferred to smaller ones. Click the icon to view the table with data you have gathered about the SUVs. Determine attribute weights and use the nondimensional scaling technique to find the resulting set of vehicle scores. Fill in the table below. (Round to two decimal places.)

-) Prof. K. took a Tesla Model S for a test drive. The car weighs 4,500 lb and can accelerate from 0 to 60 mph in 2.27 seconds. The car has a 581 kW battery pack. Help Prof. K. determine the efficiency of the vehicle [Ans. to Check 55.5%]. Note: The equation we learned in class P = F v ONLY APPLIES if velocity is constant. Use the steps below to guide your thought process. Develop a symbolic relationship for the force required to move the car forward. Compute the work done by the car (in Ib-ft). Calculate the power required to do this work (in kW). 2) After playing a game of pinball, you decide to do some calculations on the launching P Type here to search 9:09 AM 33°F Mostly sunny 3/7/2022 Esc DII PrtScn FB Home F9 End F10 PgUp PgDn Del F4 F12

A new electronic component for aircraft is tested to withstand temperatures as low as -50°F. One engineer suggests that the device cannot actually stand temperatures that low. What are the Type I and Type II errors? Type I: The device CAN NOT withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN.Type II: The device CAN withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN NOT.   Type I: The device CAN withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN NOT.Type II: The device CAN NOT withstand temperatures as low as -50F but the engineer incorrectly finds that it CAN.    Is the answer the first or second bullet point?

I submitted the below question and received the answer i copied into this question as well. Im unsure if it is correct, so looking for a checkover. i am stuck on the part tan-1 (0.05) = 0.04996 radians. Just unsure where the value for the radians came from. Just need to know how they got that answer and how it is correct before moving on to the next part. If any of the below information is wrong, please feel free to give me a new answer or an entire new explanation.   An Inclining experiment done on a ship thats 6500 t, a mass of 30t was moved 6.0 m transvesly causing a 30 cm deflection in a 6m pendulum, calculate the transverse meta centre height.    Here is the step-by-step explanation:   Given: Displacement of the ship (W) = 6500 tonnes = 6500×1000=6,500,000kg Mass moved transversely (w) = 30 tonnes=30×1000=30,000kg The transverse shift of mass (d) = 6.0 meters Pendulum length (L) = 6.0 meters Pendulum deflection (x) = 30 cm = 0.30 meters Step 1: Formula for Metacentric Height…

Solve for the indicated value, and graph the situation showing the solution point. The formula for measuring sound intensity in decibels D is defined by the equation D = 10 log (1) using the common (base 10) logarithm where I is the intensity of the sound in watts per square meter and Io = 10-12 is the lowest level of sound that the average person can hear. How many decibels are emitted from a jet plane with a sound intensity of 8.7. 102 watts per square meter? Round your answer to three decimal places. The jet plane emits Number decibels at 8.7. 102 watts per square meter.
