Answer:
Group b most likely has a lower mean age of salsa students
Step-by-step explanation:
Arithmetic Mean of the data is the average of a set of numerical values, calculated by adding them together and dividing by the number of terms in the set.
Here we are given with two groups that are Group A and Group B
both having total number of students = 20
Here the mean age of the data is addition of the all ages of different students divided by total number of students.
For group a
total age of the group = 3 × 5 + 4 × 10 + 6 × 17 + 4 × 24 + 3 × 29
= 15 + 40 + 102 + 96 + 87
=340
The mean age of salsa students= 340 ÷ 20 = 17
For group b
total age of the group = 6 × 7 + 3 × 10 + 4 × 14 + 5 × 16 + 2 × 21
= 42 + 30 + 56 + 80 + 42
=250
The mean age of salsa students= 250 ÷ 20 = 12.5
So the group b most likely has a lower mean age of salsa students

Given:
Total length of tape in roll = 16.8 meters
Length of each piece = 1.125 meters
Number of pieces = 8
To find:
The remaining tape.
Solution:
We have,
Length of 1 piece = 1.125 meters
Length of 8 piece = 8 × 1.125 meters
= 9 meters
Total length of tape in roll = 16.8 meters
Remaining tape = Total length of tape in roll - Length of 8 piece
= 16.8 - 9 meters
= 7.8 meters
Therefore, the length of remaining tape is 7.8 meters.
