Answer:What are the equivalence classes of the equivalence relations in Exercise 3? A binary relation defined on a set S is said to be equivalence relation if it is reflexive, symmetric and transitive. An equivalence relation defined on a set S, partition the set into disjoint equivalence classes
Answer:
Mean is the measure of central tendency is most appropriate to describe the given data.
Step-by-step explanation:
We are given the following in the question:
The distribution of time in seconds is a bell shaped distribution that is a normal distribution.
Properties of a normal distribution:
- The mean, mode and median for a normal distribution are equal.
- The mean divides the data into two equal parts.
- The area under the graph is 1.
- Thus, mean is the most appropriate measure of central tendency for normally distributed data.
Thus, the correct answer is
Mean is the measure of central tendency is most appropriate to describe the given data.
When y varies inversely as x it can be expressed as follows:

If we write the general equation for this

When y=3 and x=4 we can calculate de value of A

Then the equation that describes an inverse variation between x and y is_
Answer:
AC
