Is 0.346 closer to 0.34 or 0.35?
0.35
What is the formula for gradient? How do we calculate gradient?
"rise over run" (change in y divided by change in x)
Give an example of a method of collecting data
Surveys, taking measurements/ counting

11, 8, 4, 22, 6, 9, 3
9
If you rolled a dice 24 times, how many 5s would you expect to get?
