Central High School keeps a database of information about each student, including the numeric variables numberOfAbsences and gradePointAverage. The expression below is used to determine whether a student is eligible to receive an academic award.

The correct answer is: numberOfAbsences = 5, gradePointAverage = 3.8.

Explanation:

Quantitative variables are those that adopt numerical values (that is, figures). In this way they differ from qualitative variables, which express qualities, attributes, categories or characteristics.

In the set of quantitative variables, we can also recognize several types of variables:

-The continuous quantitative variables can adopt any value within the framework of a certain interval. Depending on the accuracy of the instrument that performs the measurement, there may be other values in the middle of two values. The height of a person, for example, is a continuous quantitative variable (they can be values such as 1.70 meters; 1.71 meters; 1.72 meters, etc.).

-The discrete quantitative variables, on the other hand, acquire values that are separated from each other on the scale. In other words: there are no other values among the specific values that the variable acquires. The number of pets a person has is a discrete quantitative variable: a woman can have 2, 3 or 4 dogs, but never 2.5 or 3.25 dogs.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
