b.
Answer to Problem 39PPS
The conjection is every year participants increase by 0.2(millions) from the table.
The conjection is every year participants increase by 0.12(millions) from the graph.
Explanation of Solution
Given information:
Year | Number of participants(millions) |
2000 | 1.9 |
2002 | 2.1 |
2004 | 2.4 |
2006 | 2.6 |
Formula used:
Formula of slope is,
Calculation:
From the table, every year the number of participants increase by 0.2 (millions) from the number of participants from the previous number of participants.
Hence, the conjection is every year participants increase by 0.2(millions)
From graph, substituting the values in slope formula,
So,
On solving,
Hence, the conjection is every year participants increase by 0.12(millions) from the graph.
