A meteorologist who sampled 13 randomly selected thunderstorms found that the average speed at which they traveled across a certain state was 1.7 miles per hour. The standard deviation of the sample was 1.7 mph. Find the 99% confidence interval of the mean. Do not round the t value from the table. Round the t-interval to one decimal place, example 1.2 < μ < 3.4
T value from the table for the formula:

On average, a lightning flash on Earth transfers about 30 C is transferred across 1 GV.
Suppose that, in a single lightning flash, 27.7 C of charge is transferred through a potential difference of 2.44 GV. If all this energy could be used to accelerate a car of mass 1,427 kg car from rest, what speed would the car reach, in m/s?
NOTE: 1000 m/s is 2237 miles per hour!

Java How to Program Exercise 4.11
Explain what happens when a Java program attempts to divide one
integer by another. What happens to the fractional part of the
calculation? How can you avoid that outcome?
My instructor want me to do that exercise with these details and I
am so confuse. I don't know where to start.

Hydrogen gas is a very useful reagent with many uses in the petroleum, food, and chemical industries. Most hydrogen exists in covalently bonded molecules, and atmospheric air contains less than 1 ppm of diatomic hydrogen. Therefore, hydrogen gas is produced on a large scale for these uses, where steam reforming with methane and electrolysis of water are two of the primary methods. The more economic reaction of steam reforming is the reverse of the reaction depicted in Carbon Monoxide and Hydrogen - Sample 1 in the Simulation.
Hydrogen has also been considered as an alternative fuel for vehicles designed to combust hydrogen and oxygen, which produces water as a product. However, concerns were raised because methane is typically used on a large scale to produce hydrogen gas. Assume that a gallon of gasoline contains 2400 g of carbon. If a gasoline engine achieves 30 miles per gallon, each mile consumes 80 g of carbon (about 107 g of methane contains 80 g of carbon). Alternatively, a hydrogen engine can achieve 80 miles per kilogram of hydrogen gas.
What is the mass of methane (CH4) needed to produce enough hydrogen gas (H2) to drive one mile using the theoretical hydrogen engine?

A German car will cost $45,000 and have fuel usage of
21mpg for the first 5 years, and decrease
by 1% thereafter to year 8. Repair cost will start at $1000 in year
1 and increase by 4% per year.
It will have a salvage value of $7000 at the end of year 8.
Insurance cost will be $850 the first year,
increasing by 2% per year thereafter.
The American car will cost $35,000 and have fuel usage of 20mpg for
the first 3 years, and will
decrease by 3% per year thereafter. Repair cost will be $800 in
year 1, increasing by 4% per year
thereafter. Being an American, the graduate will price the pride of
owning an American car at $0.4
for every 20 miles driven, increasing by 2% per year. Insurance
cost will be $800 per year
increasing by 2.2% per year. The car can be sold for $5500 at the
end of year 8.
If the graduate anticipates driving 150000 miles by the end of year
8 and the average interest rate
is expected to remain at 5% per year, which car is economically
affordable based on present worth
analysis? Assume fuel cost will be $3 per gallon in year 1 and
increase by an average of 2% per
year. Show all your workings.

Skysong, Inc. purchased a delivery truck for $32,400 on January 1, 2019. The truck has an expected salvage value of $2,400, and is expected to be driven 100,000 miles over its estimated useful life of 8 years. Actual miles driven were 15,700 in 2019 and 12,900 in 2020.
Compute depreciation expense for 2019 and 2020 using (1) the
straight-line method, (2) the units-of-activity method, and (3) the
double-declining-balance method. (Round depreciable
cost per unit to 2 decimal places, e.g. 0.50 and depreciation rate
to 0 decimal places, e.g. 15%. Round final answers to 0 decimal
places, e.g. 2,125.)
