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.
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.
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 gas do spiders breathe?
Air
What describes the air we breathe?
It is a gas.
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 correctly describes the air we breathe?
It is a gas.
How does the air you breathe fit the definition of matter?
The air you breathe is a gas which is one of the four physical states of matter.
The air you breathe in is 78 of what gas as is 79 of the air you breathee out?
Nitrogen
How do you know the air you breathe is matter even if you can't see it?
It doesn't matter that you can't see the air you breathe. Oxygen is gas, gas is a form of matter. So, air is matter.
