4) Temperature and elevation are related. The average temperature at the summit of Mount Everest in July is 19 Celsius. The average Temperature at the Khumbo Glacier Base Camp in July is –3 Celsius. Which is the dependent variable?

Temperature

Location

Elevation

Mountain

The dependent variable in this scenario is temperature. The reason for this is that temperature is being influenced or affected by the independent variable, which is either location, elevation, or mountain. In this case, the temperature is being influenced by the elevation, as the average temperature decreases as the elevation increases. Therefore, temperature is the dependent variable in this situation.

Explanation

The dependent variable in this scenario is temperature. The reason for this is that temperature is being influenced or affected by the independent variable, which is either location, elevation, or mountain. In this case, the temperature is being influenced by the elevation, as the average temperature decreases as the elevation increases. Therefore, temperature is the dependent variable in this situation.

5)

Is the relation a function? Explain.

Yes, it passes the vertical line test

No, it does not pass the vertical line test

Yes, it is a parabola

No, it has negative y-values

The explanation for the given correct answer is that if a relation passes the vertical line test, it means that for every x-value, there is only one corresponding y-value. This indicates that each input has a unique output, which is a characteristic of a function. Therefore, the relation in question is a function because it passes the vertical line test.

6)

This table shows the relation between the number of candy bars purchases and the total price
Write the relation as a set of ordered pairs.

{2, 11, 6, 5} {2.98, 16.39, 8.94, 7.45}

(2.98, 2), (16.39, 11), (8.94, 6), (7.45, 5)

{x | 2

(2, 2.98), (11, 16.39), (6, 8.94), (5, 7.45)

The correct answer is (2, 2.98), (11, 16.39), (6, 8.94), (5, 7.45). This is the correct answer because it represents the relation between the number of candy bars purchased and the total price. Each ordered pair represents one data point, with the first number in the pair representing the number of candy bars purchased and the second number representing the total price.

Explanation

The correct answer is (2, 2.98), (11, 16.39), (6, 8.94), (5, 7.45). This is the correct answer because it represents the relation between the number of candy bars purchased and the total price.

7) Which scenario represents a function

The number of chairs and the length of a conference presentation

The number of growth rings and the age of a tree

The style and manufacture dates of soccer cleats

The make/model of a vehicle and its color

The number of growth rings and the age of a tree represents a function because each age of the tree corresponds to a unique number of growth rings. In other words, there is a one-to-one relationship between the age of the tree and the number of growth rings it has.

Explanation

The number of growth rings and the age of a tree represents a function because each age of the tree corresponds to a unique number of growth rings. In other words, there is a one-to-one relationship between the age of the tree and the number of growth rings it has.

8)

What is the domain of the relation shown by the graph?

D = {x € R | x > 0}

D = {x € R }

D = {x € I | x ≠ 0}

D = {x € R | x ≠ 0}

The domain of the relation shown by the graph is D = {x € R | x ≠ 0}. This means that the relation includes all real numbers except for 0. The graph does not include the point (0, y), indicating that the relation is not defined for x = 0.

10) For which pair of related quantities would time be the independent variable?

Grade, time spent on project

Length of race, finish time

Flight time, rainfall

Distance to work, commute time

In this pair of related quantities, the time spent on a project is the independent variable. This means that the grade received on the project is dependent on the amount of time spent working on it. The more time spent on the project, the potentially higher the grade. The grade is influenced by the amount of time invested in the project, making time the independent variable.
