Using Trend Lines Quick Check unit 5 lesson 7
1 - The slope means that, for every phone assembled, you receive $1.50. The y -intercept means that you receive $20 a day regardless of the number of phones produced.
2 - For every year since 1900, the population grew by approximately 650. In 1900, the population was 20,000.
3 - In 2030, the population of the state will be 54.9 million people
4 - The average final grade is 27% if a student spent 10 hours on social media.
5 - After 60 seconds of skiing, you will be 4,200 feet high.
1 - The slope means that, for every phone assembled, you receive $1.50. The y-intercept means that you receive $20 a day regardless of the number of phones produced.
This statement accurately describes the meaning of slope and y-intercept in the context of a trend line. The slope represents the rate of change, which in this case is $1.50 for every phone assembled. The y-intercept represents the starting point or fixed value, which in this case is $20 a day regardless of the number of phones produced.
2 - For every year since 1900, the population grew by approximately 650. In 1900, the population was 20,000.
This statement accurately describes the trend line for population growth. The slope represents the rate of growth, which is approximately 650 people per year since 1900. The starting point or y-intercept is given as 20,000, which represents the population in the year 1900.
3 - In 2030, the population of the state will be 54.9 million people.
This statement accurately predicts the population in the year 2030 based on the trend line. It suggests that the population will be 54.9 million people in that year. However, without further information about the trend line equation or data, we cannot confirm the accuracy of this prediction.
4 - The average final grade is 27% if a student spent 10 hours on social media.
This statement does not align with the concept of a trend line. A trend line usually represents a relationship between two variables, and the statement only provides information about one variable (hours spent on social media). Additionally, without more data or information, we cannot determine the accuracy of this statement.
5 - After 60 seconds of skiing, you will be 4,200 feet high.
This statement does not align with the concept of a trend line. A trend line typically represents a relationship between variables over a period or range. The statement only provides information about a single point in time (60 seconds) and height (4,200 feet). Additionally, without more context or data, we cannot determine the accuracy of this statement.
