The current speed limit on certain highways in the United States is 65 mph. What is the speed limit in km/s?ys in the United States is 65 mph. What is the speed limit in km/s?
A section of U.S. highway with a posted speed limit of 70.0 mph (113 kph) has a curve of radius 1,170 ft (357 m). At what angle should the curve be banked so that cars travelling at the speed limit have no tendency to skid sideways? Bank angle: ______________° What if the road were on Mars? (Martian surface gravity is 3.71 m/s².) Assume the same coefficient of friction for a dusty road on Mars as for a wet road on...
Do drivers follow the posted speed limit of 65 mph on Interstate 270? The following data give the speeds (mph), as measured by radar, of 10 randomly selected cars traveling on Interstate 270: 76 72 80 68 76 74 71 78 82 64 Assume all conditions are met for confidence intervals. Find a 99% confidence interval for the population mean speed of all drivers on I-270. [3] Find a 95% confidence interval for the population mean speed of...
1.If we changed our speed limit signs to metric, what would probably replace the following? (Enter your answers to the nearest km/h.) (a) 15 mi/h km/h (b) 80 mi/h km/h 2.A quantity of water is poured into a graduated cylinder, which then reads 154 mL. What is the mass of the water in kilograms?
The speed limit on the New York State Thruway is 65 m.p.h, exactly. Considering that 1.00 mi. = 1.61 km, what would the speed limit be in k.p.h. if the United States were to convert to the metric system. Show your work and express your answer to the proper number of significant figures.

The speed limit on the freeway is 65 mph. The chief of the police department has their radar guns tested: from repeated measurements, the errors in the readings seem to follow a normal distribution. Using the data and assuming the radar guns provide unbiased measurements of the true speeds, the chief issues a policy that officers should not stop cars unless the reading is at least 71 mph. She says this policy ensures that no more than 2.5% of cars...
if we changed our speed limit signs to metric what would probably replace 60 mi/h
2. Data was collected from a highway with a 65 mph speed limit. A speed “gun” sampled 12 random vehicles and found the mean to be 60.67 mph with a standard deviation of 4.08 mph. i. Which model would be used to construct a confidence interval for the mean 2i) speed of all vehicles on that highway? a) students-t b) least squares linear regression c) Binomial d) Normal ii. The standard deviation for this sampling distribution would be calculated using,...
1. The speed limit on some interstate highways is roughly 100 km/h. (a) What is this in meters per second? (b) How many miles per hour is this?
