I got the right answer just by guessing. Please explain how to do it! i will...
Please only answer 5,6,7 ASAP i will rate thumbs up? 3. (26 pts.) The damping ratio (y) of a polymer material is measured at various temperatures (*) as shown in the table below. Temperature (°C), x Damping ratio (%), y, 10 8 2010 30 15 0 10 20 30 40 (1) (14 pts.) Determine the regression equation of y on x in the form, y = a +bx. (So, you need to determine a and b.) (2) (2 pts.) Determine...
Hi can someone please show how this is solved, I have the answer as = 497.9 +/- 0.73 ngL-1 but would just like to know how the answer was reached. Especially to the +/- 0.73 ngL-1 Thank you. 4. The calibration data for the determination of lead levels in fruit juices by a differential pulse polarography method is shown below. 40 10 30 20 50 Current /HA0.0000.1180.2400.5070.7130.9811.183 When these data were plotted using linear regression a correlation coefficient, R2, of...
Hi, I need help with this question. Please explain in details how you got the answer with steps shown for each part so I can understand it thank you. The mean x and standard deviation s measure center and variability but are not a complete description of a distribution. Data sets with different shapes can have the same mean and standard deviation. (Data set may be found here. Round your answers to two decimal places.) Data A: 9.14 8.14 8.74...
ignore my answers i was just guessing The manager of a travel agency has been using a seasonally adjusted forecast to predict demand for packaged tours. The actual and predicted values are as follows: Period Demand 140 Predicted 120 200 150 AWN- 194 169 100 80 136 128 O V 95 124 101 150 149 105 94 85 84 140 128 134 The following data were collected during a study of consumer buying patterns: Observation Observation AWN b. Obtain a...
can someone help me with this prelab? and explain the answers you got? thank you in advance! 1. Draw a graph of the equation: y 4.9 m/s2 t2 with horizontal axis (t) spanning from O to 2 seconds and vertical axis (v) spanning from 0 to 5 meters. (Note: This is different from last week's pre-lab ir which you graphed y vs. t2, here we are asking for you to graph y vs. t). 2. In generating a best fit...
Simplify the following circuit (x, y, z) = ∑m(2, 3, 4, 5) The answer I got was F=YZ' + Y'Z please dont give me the answer just tell me if I got the right answer or not thank you.
My last question has gone hours without being answered, so I am submitting these again. Anyone who could help with these 10 questions would be MASSIVELY appreciated. Thank you!! 11.

How do I find the expiremental resistance? 3 QUESTIONS&CALCULATIONS Using your graph and equation of best fit determine the experimental resistance of each resistor. (Hint: consider how the slope of the graph is related to the resistance.) 1. experimental resistance #1 experimental resistance #2 |-)- 2. Calculate the percent error for each resistor by comparing them to the known value found using the ohmmeter. Show your work for the error calculations. Use exact values from earlier calculations to find the...
