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

Answer:
Step-by-step explanation:
Answer:
discount= $94.5
Proceeds=$2605.5
Step-by-step explanation:
amount Dawin has to pay= $2700
in 6 months time
at a discount rate of 7%
here future value = $2700
D= discount before m months is given by
m= 6 months, r= 7% and FV= 2700
putting values
solving we get
D= $94.5
now present value = future value - discount
=2700-94.5= $ 2605.5
here PV(present valve )= Proceeds= $2605.5
It would be 544,000
hope this helps you
Hello!
First you have to find BO
BC = 27
AO = CO
CO = 24
BO = 27 + 24
BO = 51
Now we use the Pythagorean Theorem
24^2 + b^2 = 51^2
Square the numbers
576 + b^2 = 2601
Subtract 576 from both sides
b^2 = 2025
Take the square root
b = 45
The answer is A) 45
Hope this helps!
