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?
A projectile launched at initial speed of 75 m/s at an angle of 30 degrees travels a horizontal distance of 421.2 m. How long did the projectile travel before hitting ground? Calculate the maximum height this projectile can reach.
A mortar is fired from ground level at an angle of 75 degrees with respect to the horizontal. If the projectile leaves the mortar barrel at a velocity of 280 m/s, what is the horizontal distance between the mortar and the point of impact
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?
Why do you think measuring the variability of a data set is important? Describe what a standard deviation is conceptually. How would you use it in your daily life or in your job now? Please provide short examples.
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.
