The distribution of passenger vehicle speeds traveling on the Interstate 5 Freeway (I-5) in California is nearly normal with a mean of 72.6 miles/hour and a standard deviation of 4.78 miles/hour (A) Slower than 128 km/hour? (1 km = 0.62 mile) (B)The speed limit on this stretch of the I-5 is 65 miles/hour. What percentage of the passenger vehicles travel above the speed limit on this stretch of the I-5? Are you surprised at the result? In other words, Is this probability unusual? Note: If probability is < 0.05 then it is unusual. (C) What speed interval should the authorities expect to find the middle 70% of passenger vehicle to travel? (D) What is the IQR of the passenger vehicle speed in Interstate 5 Freeway in California? In other words, find the cutoff value for the middle 50%. (E) How slow do the slowest 10% of the passenger vehicles travel?

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
