Describe how you would construct an angle measuring 75 degrees.
The proper angle for a ladder is about 75 degrees from the ground. Suppose you have a 6 foot ladder. How far from the house should you place the base of the ladder? Round to the hundredths. (2 decimal places) feet
How do you find the angle of the ramp you use in measuring the frictional coefficient?
5. Describe in detail how you would construct a 95% confidence interval for a set of 30 data (4 points) points whose mean is 20 and population standard deviation is 3. Be sure to show that you know the formula and how to plug into it. Also, clearly state the margin of error 6. If the margin of error in an estimate for the mean weight of a shipment is + or -2 pounds at a (4 points) confidence level...
Using the concept of of "Matched Pairs t Procedures" , describe how you would construct a comparison between two Automotive Repair facilities to see if there was a better alternative, in general. This means you need to determine sample size, how the the design would be implemented, and what the hypotheses are. This is similar to Round Robin testing in a laboratory or a "pretest/post test" study at the university. This discussion should be more than a single paragraph and...
Describe how you could calculate the mass of metal plated onto an object, besides measuring the difference in masses (include reactions and equations).
You can determine the index of refraction of a substance by measuring its critical angle for total internal reflection. Randomized VariablesΘc,w = 63.8° a) What is the index of refraction of a substance that has a critical angle of 63.8° when submerged in water (with index of refraction 1.333)? b) What would the critical angle be for this substance in air?
When measuring the speed of blood from the sternum to the finger tip, how would you explain the difference in speed from a condition of arm relaxed to a condition of arm up? 1 i. B II ! ! % 3 c <> Explain what the two graphs below represent. Briefly describe the experiment and explain what caused the change in the amplitude and frequency of each event in the two graphs.
You throw a baseball at an angle of 60 degrees with respect to the horizontal with a speed of 20 m/s as it leaves your hand. a. Making reasonable simplifying assumptions, how far from you is the ball when it lands. b. It is possible to throw a second baseball from the same location and with the same initial speed (20 m/s) but at an angle of 30 degrees with respect to the horizon, and this second ball can land...
The refractive index of a transparent material can be determined by measuring the critical angle when the solid is in air. If Oc= 40.4º what is the index of refraction of the material? 1.54 You are correct. Previous Tries A light ray strikes this material (from air) at an angle of 37.2° with respect to the normal of the surface. Calculate the angle of the reflected ray (in degrees). 23.07 Submit Answer Incorrect. Tries 3/20 Previous Tries Calculate the angle...
2. Describe how you would construct a purely seasonal model for the following monthly series. In partic- ular, what dummy variable() would you use to capture the relevant effects? (a) A sporting goods store finds that detrended monthly sales are roughly the same for each month in a given 3-month season. For example, sales are similar in the winter months of January, February, and March, in the spring months of April, May, and June, and so on. (b) A campus...
