Which dot plot has more than one mode?

The dot plot representing the calico crayfish has more than one mode.

Step-by-step explanation:

We know that mode of the data is the value corresponding to the highest frequencies.

or we may say the mode of a data set is the number that occurs most frequently.

Clearly from the dot plot we could see that the data representing the calico crayfish have two quantities with four dots ( one is when number of calico crayfish are 5 and the other when number of calico crayfish are 8)

Also by making a frequency table we may check it as:

Number of calico crayfish         frequency

      1                                                    1

      2                                                   0

      3                                                    1

      4                                                    3          

     5                                                    4

      6                                                     1    

      7                                                     2

      8                                                     4  

      9                                                     0  

     10                                                     2

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12
