8) In 1963, the number of cars in the U.S. was about 1.7 million. By 1988, it had increased to about 2.9 million. Write an exponential function in the form y= ab* that could be used to model the number of cars y in millions for 1963 to 1988. Write the equation in terms of x, the number of years since 1963. Round the value of b to the nearest thousandth. 9) Suppose the number of cars continued to grow at that rate. Estimate the number in 2005.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
