Answer:
the one the has the points of (4,5) and (-1,1)
Step-by-step explanation:
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:
Francine run 5.495 miles
Step-by-step explanation:
Given :
Francine ran laps around the circular track in the school gym.
The track has a diameter of 1/2 miles.
To Find : About how far does Francine run?
Solution :
First we need to calculate the perimeter of circular track :
Perimeter of circle :
Since we are given the diameter = 1/2 miles = 0.5 miles
So, Radius will be (Diameter/2) = 0.5/2 = 0.25 miles
So, The perimeter will be:
Since
⇒
⇒
Thus the circular track is of 1.57 miles .
Since she ran = 7/2=3.5 laps
1 lap = 1.57 miles
So, 3.5 laps = 1.57*3.5 =5.495 miles .
Hence , Francine run 5.495 miles

Factor the polynomial:
4u² – 20u + 25
Rewrite – 20u as – 10u – 10u, and then factor it by grouping:
= 4u² – 10u – 10u + 25
= 2u * (2u – 5) – 5 * (2u – 5)
= (2u – 5) * (2u – 5)
= (2u – 5)² <––– this is the answer.
I hope this helps. =)
