The standard deviatiion is the square root of the variance.
Let's assume initial population is in 1999
so, production of passenger cars in Japan is 3.94 million in 1999
so, P=3.94 million
and the production of passenger cars in Japan is 6.74 million in 2009
so, A=6.74 million in t=2009-1999=10 years
now, we can use formula

here , r is interest rate
so, we can plug values

now, we can solve for


so,
the geometric mean annual percent increase is 5.516%............Answer
Radius= 1/2 diameter
Radius= 1/2(30)
Radius= 30/2
Radius= 15 feet
Circumference= 2πr
C= 2(3.14)(15)
C= (6.28)(15)
C= 94.2 feet
ANSWER: Radius is 15 feet; Circumference is 94.2 feet
Hope this helps! :)
Answer:
A. 13
Step-by-step explanation:
2(x - 3) + 3y
2(5 - 3) + 3×3
2× 2 + 3×3
4 + 9
13
360/18=20
So, your answer is 20 unit rate.
Hope this will help you!
