The average gas mileage of a certain model car is 28 miles per gallon If the gas mileages are normally distributed with a standard deviation of 1.7 find the probability that a car has a gas mileage?
That's on page 126 in your statistics textbook...... DO YOUR OWN HOMEWORK!!! K i obv needed help with how to do it, ass. I didn't want just the answer.
Does the average gas bill vary according to the number of people in the household?
Yes it does, depending on what sort of heating you have in the house. If you have gas hot water it will vary quite a lot as it will be on for longer with an extra person or two.
Is it true that every breath of air contains at least 1 atom that every human ever born has breathed?
Yes. There are 6.02 x 10e23 molecules in a mole. 2 atoms of oxygen in a molecule of oxygen. Nitrogen molecule also 2 atoms. A mole of gas is ~22.4 liters. A normal resting breath of air for an adult is ~500mL Roughly 99% of air is either oxygen molecules or nitrogen molecules. [(0.5 liters/breath) divided by (22.4 liters/mole)] times (6.02 x 10e23) equals ~ 1,340,000,000,000,000,000,000 molecules in every breath Given that O2 and N2 have 2 atoms/molecule, there would be twice as many atoms ~2,700,000,000,000,000,000,000/breath you'd probably have millions, if not billions of atoms that had been breathed by any person who'd ever lived.
What is the difference between quantitative and qualitative observations?
Qualitative refers to what a sample is, while quantitative refers to how much of that material is present. For example, the "squeaky pop test," which involves taking a burning splint and immersing it in a test tube, is a qualitative test. If the gas in the test tube pops, you know you have hydrogen production. In this case, no numbers are being taken - it is only to identify the gas in the test tube. Say you capture the gas released by whatever reaction takes place in the test tube. Measuring the volume of the gas would be the quantitative observation.
What technique may be used to test for T-2 mycotoxins in enviromental and clinical samples?
gas liquid chromatography-mass spectrometry technique
What percentage of gas is in the air you breathe out?
men
The gas that makes up the largest percentage of the air?
Nitrogen is the gas that makes up the largest percentage of the Earth's atmosphere, composing about 78% of the air we breathe.
What is the name of the gas that you breathe in from the air?
The gas you breathe in from the air is called oxygen.
What is the richest source of nitrogen on a mass percentage?
The richest source of nitrogen on a mass percentage is the atmosphere, where it makes up about 78% of the air we breathe. Nitrogen gas (N2) is abundant in the atmosphere but not readily available for use by most organisms in that form.
Which gas is 20 percent of the air you breathe?
Oxygen is approximately 21% of the air we breathe.
What type of gas makes up the highest percentage of air?
Nitrogen makes up about 78% of Earth's atmosphere.
Is nitrogen the gas with the highest percentage by volume in dry air?
Yes. Nitrogen makes up about 78.08% of the air in Earth's atmosphere by volume.
What gas do spiders breathe?
Spiders breathe in oxygen like humans do. They have small breathing holes called spiracles located on the underside of their abdomen that allow them to take in oxygen from the air.
What describes the air we breathe?
It is a gas.
The air that you breathe is an example of a?
Gas
How much nitrogen do you breathe in?
Approximately 78% of the air we breathe is nitrogen. Nitrogen makes up the largest percentage of our atmosphere compared to any other gas.
Percentage of argon in the air you breathe?
Argon makes up about 0.93% of Earth's atmosphere. This inert gas is non-toxic and does not react with other elements, so it is safe to breathe.
