Answer:
Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is
Step-by-step explanation:
Evaluate:
When a=-4, b=2, c=-3, and d =4
Solution:
Substitute, a=-4, b=2, c=-3, and d =4 in above expression we get
Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is
I would go with b. the mean age of all students in her middle school is likely to be close to 11.6.
Because she used a simple random sample, the outcome is likely to be an accurate representation of the entire middle school. It might not be exact, but likely close to 11.6.
