## Ratios and Probability

Suppose the probability that a basketball player makes a basket from the free throw line is 0.75. Since the decimal 0.75 means seventy-five
hundredths, the probability can also be expressed as the ratio
.
This means that the player makes a free throw 75 out of 100 times. In
this lab, you will explore ratios and probability. Continue reading “Ratios and Probability”

## Exploring Ratio, Proportion, and Percent

In this chapter, students learn to express ratios and rates
as fractions and to solve proportions by using cross
products. Then, using their knowledge of ratios, students
find actual lengths from scale drawings. Students explore
the relationship among fractions, decimals, and percents
as well as find the percent of a number. Students also
learn to solve problems by drawing a diagram. Continue reading “Exploring Ratio, Proportion, and Percent”

## Exponential Functions

There are two types of exponential functions: .exponential growth and exponential decay The base of an exponential growth function is
a number greater than one. The base of an exponential decay function is a number between 0 and 1.

Exponential functions are frequently used to model the growth or decay of a
population. You can use the y-intercept and one other point on the graph to write the equation of an exponential function. Continue reading “Exponential Functions”
