Answer:
The standard deviation reduces when sample size (n) increases
Step-by-step explanation:
From the above information given, we have that mean = 75.5
Standard deviation = 3.5
But Standard deviation = √summation (x-u)/n
This simply implies that when sample (n) is increased there would be a reduction in the standard deviate.
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
as it shows, its a 90 degree angle, when having 40 degrees on one side, then you must have to have 50 degrees on the other side to equate to 90.
Formula for circumference = πD (where D is the Diameter)
Since diameter = 2 x radius, we can also write the formula as :
Formula for circumference = 2πr (where r is the radius)
5x11=55
55/2=27.5
Area: 27.5 in
