Divide both sides by :
If , then
and more generally, for any integer ,
Answer:
20
Step-by-step explanation:
The question states that the sample size is 16 and standard deviation of sampling distribution of sample mean also known as standard error is 5. This information can be written as
σxbar=standard error=5 ,n=sample size=16.
We have to find population standard deviation σ.
We know that
<em>Population standard deviation=</em>σ=4*5=20
The answer is: [C]: 61.38 cm .

300 = (3.14) * r² ;

Divide each side by "3.14" ;
r² = 300/3.14 ;
r² = 95.5414012738853503 ;
√r² = √(95.5414012738853503) ;
r = 9.7745281867661188048
Circumference, "C" =
* d ; (d = diameter = 2*r);
C = 2**r ;
C = 2*(3.14)*(9.7745281867661188048)
C = 61.384037012891226094144 ; which rounds to answer choice:
[C]: 61.38 cm .
