Which statement best compares the variability of the number of snacks grabbed for Class A and Class B?
1 answer:
*see attachment below for the dot plots
Answer:
A. The number of snacks grabbed for Class A has less variability than the number of snacks grabbed for Class B.
Step-by-step explanation:
The extent of variability of the data represented on a dot plot can be determined by the range value.
Range is the difference between maximum value of the data set and the minimum value of the data set.
The larger the range, the more the data has more variability, while the smaller the range, the less the variability of the data.
Range for Class A = 37 - 15 = 22
Range for Class B = 45 - 12 = 33
Therefore, class B has more variability in the number of snacks grabbed compared to Class A.
Correct statement is: "The number of snacks grabbed for Class A has less variability than the number of snacks grabbed for Class B."

Answer: D
Given :
Distance travelled , d = 180 miles.
Time taken , t = 4 hours.
To Find :
Speed in feet per minutes.
Solution :
Distance in feet is , d = 180×5280 = 950400 feet.
Time taken , t = 4×60 = 240 minutes.
Speed is given by ,
Hence, this is the required solution.
