Answer:

Step-by-step explanation:

A half rest is 2 beats, a quarter rest is 1 beat, so the rests on the left total 3 beats.

The half note on the right is normally 2 beats, but the dot adds half-again that amount, so 1 more beat. The dotted half note on the right is 3 beats.

Both represent 3 beats, so their beat counts are "equal."

Serial numbers for a product are to be made using 3 letters followed by 3 digits. The letters are to be taken from the first 5 l

Bezzdna [24]

Answer:

43,200 serial numbers can be generated

Step-by-step explanation:

The ordering for the letters and the digits are important. For example, 012 constitutes a different serial number than 210. So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

How many serial numbers can be generated

3 letters, from the first five of the alphabet

3 digits, from a set of 10

$T = P_{5,3}*P_{10,3} = \frac{5!}{(5-3)!}*\frac{10!}{(10-3)!} = 43200$

43,200 serial numbers can be generated
