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

<span>The first step in finding the surface area of a cone is to measure the radius of the circle part of the cone. The next step is to find the area of the circle, or base. The area of a circle is 3.14 times the radius squared (<span>πr2</span><span>). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius.
You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (</span>πrl<span>).
So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:</span>
<span>SA = πr2<span> + πrl</span></span><span><span>

Answer:
11314.87379 (This is still rounded).
Step-by-step explanation:
Year 1:
9300*4%=372. 9300+372=9672.
Year 2:
9672*4%=386.88. 386.88=10058.88.
Year 3:
10058.88*4%=402.3552. 402.3552+10058.88=10461.2352.
Year 4:
10461.2352*4%=418.449408. 418.449408+10461.2352=10879.68461
Year 5:
10879.68461*4%=435.1873843. 435.1873843+10879.68461=11314.87379.
