Answer:
a) The symbol for sample standard deviation is S
b) The symbol for population standard deviation is б (sigma)
c) The symbol for sample variance 
d)The symbol for population variance is 
Step-by-step explanation:
Step 1:-
Population:- Population consists of the total of the observations with which we are concerned.
Parameters:- The statistical constants of the population namely mean , variance
and standard deviation 'б '
Sample:- A sample is a subset of a Population
statistics:-
he statistical constants of the sample namely mean , variance
and standard deviation 'S '
step2:-
a) The symbol for sample standard deviation is S
b) The symbol for population standard deviation is б (sigma)
c) The symbol for sample variance 
d)The symbol for population variance is 
Answer:
60
Step-by-step explanation:
All the angles in that triangle are the same due to the type of triangle.
The first circle is approximately 44 times greater than the second cirle
Radius = 110 mm
110² = 10,000 mm² = Area
Radius = 15 mm
15² = 225 mm² = Area
