Chapter 3: 13. What type of geometric tolerance has no datum features? 14. A theoretically exact dimension is called a 15. The feature symbol specifies that a group of two or more interrupted features of size are to be considered one single feature of size. 16. For an individual regular feature of size, no element of the feature shall extend beyond the maximum material condition boundary (envelope) of perfect form. This statement is the essence of 17. What is the name of the symbol used to identify physical features of a part as a datum feature and must not be applied to centerlines, center planes, or axes? 18. The is the condition in which a feature of size contains the maximum amount of material within the stated limits of size. 19. The total positional tolerance equals the sum of the tolerance and the tolerance.

Part 1: Suppose that our company performs DNA analysis for a law enforcement agency. We currently have 1 machine that are essential to performing the analysis. When an analysis is performed, the machine is in use for half of the day. Thus, each machine of this type can perform at most two DNA analyses per day. Based on past experience, the distribution of analyses needing to be performed on any given day are as follows: (Fill in the table)   Part2: We are considering purchasing a second machine. For each analysis that the machine is in use, we profit 1400$. What is the YEARLY expected value of this new machine ( ASSUME 365 days per year - no weekends or holidays

Can I get some help on this question please, thank you very much.

Your professor has recruited you to work in her lab to help her win the Nobel Prize. It is critical that your work be as accurate as possible. Rather than using the stated volumes of glassware in the lab, you decide to calibrate each piece. An empty 10-mL volumetric flask weighed 10.263 4 g. When filled to the mark with distilled water at 208C, it weighed 20.214 4 g. What is the true volume of the flask?

1. Since experimentations are always subject to errors, what techniques are employed to neutralize the effects of these errors in the accuracy and validity of the experiment? 2. Why is the "factorial experiment" better in any way than a "one-factor-at-a-time" approach? 3. True or False: As soon as the experimental data (measurements) are obtained, the experimenter can already proceed with the usual significance testing. Explain. 4. What is "hypothesis testing"? How is it performed? 5.What makes ANOVA a powerful tool in hypothesis testing? What happens if you use a 2k full Factorial design to explore a set of variables which is known to have a non-linear response? 6. When is the addition of center points to a 2k full factorial design beneficial? Give a particular case that warrants its use. 7. In practical terms, explain how a LOW p-value connote SIGNIFICANCE (Recall that the smaller the p-value is, the more significant the factor becomes)?

(d) Based on the situation below, give one type of error faced by Ali's and give the suggestion how Ali's can make the reading become accurate and precise. Ali uses a vernier caliper to measure the diameter of 3 tubes. Then, the readings are compared to the actual values of the tubes as shown in Table 1: Tubes number Actual value Reading measurement 0.05 mm No tube Tube 1 5.05 mm 5 mm Tube 2 10.05 mm 10 mm Tube 3 12.05 mm 12 mm Table 1

Newton's Law of cooling states that the rate at which heat is lost by a heated body is proportional to the difference in temperature between the body and the surrounding medium. Match the following statements/phrases with the corresponding item in the drop down box. Choices in the box 1. In accordance with the stated law obove, we have the equation? 2. If a thermometer is taken outdoors where the temperoture is 5 deg C, from a room in which the temperature is 20 deg C and the reading drops 10 deg C in one minute, the working equation is? 3. In the obove problem, separoting the variables and integrating will result to? 4. In the obove problem, how long, in minutes, after its removal from the room will the reading be 6 deg C? 5.

A. A customer asked you to explain your choice of a temperature sensor that you used for his PCB. Initially, there were two sensor options. To compare between them, you decided to test their accuracy and precision. Accuracy of a sensor is a measure of how near its reading is to the real value, the nearer the measured value to the real value the better. While precision is a measure of how widely spread the readings of a sensor are [relative to each other] when measuring the same variable, the narrower the spread the better. So, you tested the two sensors by measuring the same temperature, which was 100 C of boiling water, and you recorder the following 10 measurements of each sensor. Which Sensor has higher accuracy, and which one has higher precision. Sensor Sensor readings when measuring 100 C 99.65 100.05 103 102 99.3 s1 100.1 99.1 100.5 99 98.8 98.78 96.9 101.4 98.88 99 S2 99.12 98.9 99 98.69 99.2

Select all true statements. O To obtain a mining lease, the holder of a mining claim must absolutely acquire surface rights. | Mechanized stripping is used to expose the bedrock linearly to test the geological unit of interest on its full width, perpendicular to its contact with the surrounding units. The apparent length of a mineralized zone of interest is always shorter than its true width. Upon reaching commercial production, the purchaser of a mineral exploration property can pay a certain amount to the seller in exchange for a reduction of the percentage of the Net Smelter Return (NSR) retained by the seller.

We wish to measure a characteristic of a machined part whose nominal size is 50 mm at 20 °C. For this, two different instruments are used; an analog micrometer and a digital vernier caliper, both recently calibrated and with the same resolution (0.01 mm). The calibration certificate data of the analog micrometer and the digital vernier are shown in tables 5 and 6 respectively. In both cases the calibration uncertainty does not include the contribution of resolution uncertainty. Additionally, there are drift studies for both instruments and it is established that the drift of the micrometer is ± 0.002 mm while the drift of the vernier is ± 0.02 mm.   The same number of measurements were performed with both instruments to avoid repeatability biases under controlled environmental conditions. Table 7 shows the results of the measurements of both instruments. The temperature of the piece was monitored with a digital thermometer whose calibration uncertainty is 0.1 °C, which already includes…
