Graphs can graph most mathematical functions, showing them visually. A linear equation, such as "y = 2x + 3", appears on the graph as a straight line. A second-degree equation, such as "y = 3x ^ 2 + 2x + 3, " appears as a parabola. Circles in the graphs also have equations , which combine multiple quadratic expressions..
When an object is placed in a liquid, the liquid exerts pressure on all sides of the object . The pressure from below exerts a force on the object that pushes it up, so we can define the force of thrust as the force that occurs when an object is submerged in water. If the object is less dense than the liquid, it will float..
The points in a scatter plot relate different quantities to determine the relationship between them . Sometimes, the points will not have a pattern, which indicates a correlation. But when the points show a correlation, a line of best fit is shown in the extent of the connection. The sharper the slope of the line that passes through the points, the greater the correlation between the points..

Using percentages to determine the probability allows you to determine the possibilities on the outcome of an event..
Probability is a statistical measure that shows the probability of something happening . You can hear examples of probability on a daily basis, such as a meteorologist describing a 75 percent chance of rain, or a news anchor citing one at 10 million odds of winning the lottery. The probability of an event occurring is a fraction or a percentage between 0 and 1 ..
There are two methods by which you can calculate the number of days between two dates . The first is simply to count the days in a calendar. The second method uses addition and subtraction to make the calculation. For this method, it is important to know how many days you have each month.
