Price of book in 1938 = $ 0.10
Price of book in 2011 = $ 2,161,000
Number of years over 1938-2011 = 2011 - 1938 = 73
Annual increase in the price = 
⇒ Annual increase in the price = 
⇒ Annual increase in the price = (1.260302283 - 1 ) × 100
⇒ Annual increase in the price = 0.260302283 × 100
⇒ Annual increase in the price = 26.0302283 %
⇒ Annual increase in the price = 26%
Hence, the comic book price increased by 26% annually
Answer:
For the shape you must do 3*3*3 + 2*2*2 + 1 unit cubed, or 36 units^3
For Jessy's jewelry box, you must multiply the side lengths, 3*10*3, or 90 inches^3
The answer to your question is 9
Answer: (3.46, 3.62)
Step-by-step explanation:
The formula to find the confidence interval for population mean is given :-
, where n = sample size.
= Two-tailed t-value for significance level of
and degree of freedom df= n-1.
= sample standard deviation.
As per given , we have
mm
s= 0.20 mm
n= 25
Significance level 
Since population standard deviation is not given , it means the given problem has t- distribution.
Two-tailed t-value for significance level of
and degree of freedom df= 24:

95% Confidence interval for population mean:
Hence, the 95% two-sided confidence interval for the mean glass thickness = (3.46, 3.62)
