Here are the answers to the questions based on the provided information:
### Question 1
**What type of association does the graph show between x and y?**
- Given the ordered pairs (1, 1), (2, 2), ..., (10, 10), the association is a perfect straight line with a positive slope. Thus, the correct choice is:
- **Linear positive association**
### Question 2
**Which point on the scatter plot is an outlier?**
- In the given points, (9, 50) appears to be significantly higher than the others. The likely outlier is:
- **Point P (9, 50)**
### Question 3
**What type of association will the scatter plot for this data represent?**
- The given data for bakers and cakes baked suggests a positive trend, although not perfectly linear. The best option is:
- **Positive linear association**
### Question 4
**What is most likely the line of best fit for this scatter plot?**
- Without visual access to the graph, a general recommendation would be to choose the line that best approximates the trend of the data, which is typically the one that balances the distance from all points. The correct line based on a description would be:
- **Line C** (if it best fits the trend from (0, 1) to (14, 14); otherwise, select the one showing the best fit).
### Question 5
**Which graph best represents the line of best fit for this scatter plot?**
- Again, without visual accompanying graphs, based on the description, the one that seems the most reasonable should fit through most of the points shown without ignoring existing data. I would suggest:
- **A graph that joins points close to the trend visible from the data set. Choose accordingly.**
### Question 6
**Which statement is most likely correct about the line?**
- Generally, the line of best fit doesn’t have to pass through every point, it only needs to represent the trend accurately. This would lead to:
- **It can be a line of best fit because it is closest to most data points.**
### Question 7
**What is the slope of the equation?**
- From the equation y = 7x - 9, the slope is clearly indicated as:
- **7**
### Question 8
**What is the approximate equation of this line of best fit?**
- Given the description, it seems reasonable to assess the slope from provided point coordinates. The appropriate answer would likely be:
- **y = 5/7x + 1** (If this fits the most accurately with the information provided.)
### Question 9
**What will most likely be Jamie's approximate science score if he does science homework for 7 hours a week?**
- Given the trend from the previous data, one should extrapolate the score from the equation or previous score line. An approach could yield:
- **83 points** (If we follow the linear trend).
### Question 10
**What is the missing number in the table?**
- To complete the two-way table, it’s essential to calculate the values based on those given. Without specific details about the logic for deriving the missing numbers, but given familiarity with the distributions:
- **10** (might fit based on total calculations).
### Question 11
**How many more students like baseball than tennis?**
- The totals for baseball (40) and tennis (40) indicate neither exceeds the other. Hence, the evaluation yields:
- **0** (assuming equality, but since that’s not an option, the calculations would require reevaluation).
### Question 12
**If a student does not like pink, what is the probability that student also does not like black?**
- This probability can be computed directly from the table data:
- Total who do not like pink = 32; those who don’t like both colors = 9. Therefore:
- **Probability = 9/32 = 28.1%**
Feel free to ask if you want further details or clarifications on specific answers!
