Answer:
4
Step-by-step explanation:
The greatest common factor (GCF) is the highest factor of two numbers...
4 (4) = 16
3 (4) = 12
4 is a factor of both 12 and 16. It is also the greatest factor of the two numbers. For example, 2 is also a factor of 12 and 16. However, it is not the greatest number... 4 is.

Step-by-step explanation:
Answer:
B
Step-by-step explanation:
• A line sloping upwards from left to right has a positive slope
• A line sloping downwards from left to right has a negative slope
The line shown here slopes downwards from left to right, hence has a negative slope → B
Put the numbers in order
5, 8, 10, 20, 25, 30, 35, 40, 45
Q1 = (8 + 10) / 2 = 18/2 = 9
Q2 -- median = 25
Q3 = (35 + 40)/2 = 75/2 = 37.5
the upper quartile (Q3) = 37.5
