What is clustering? A. a data point that does not fit the general pattern in the data
B. a group of data points around a value
C. a relationship between two variables
D. a graph showing the relationship between two sets of data

B. a group of data points around a value

Step-by-step explanation:

A cluster in math is when data is clustered or assembled around one particular value.

the upper bound for the length 370 mm is alos 370 mm because there is no other number that can be rounded down to 370 that also has 2 significant figure. b. area = 370 x 19.4 = 7178.0 so the lower bound is 7177.5

Hope this helps
