600000 = 6*10^5
80000 = 8*10^4
10 =10
the number together is:680010
= 6.8 *10 ^5
Answer:
The 90% confidence interval for population mean length of eastern rods is (23.73, 24.07).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean when the population standard deviation is not known is:
The information provided is:
Compute the 90% confidence interval for population mean length of eastern rods as follows:
Thus, the 90% confidence interval for population mean length of eastern rods is (23.73, 24.07).
(32.75+39.88) =72.63= cost of both meal. 14% of this total cost would be 10.1682. then add that to the cost of the meal to get the total cost. 72.63+10.1682=$82.80 (rounded to nearest cent)
0.004, because the decimal place moves left by one spot when dividing by ten.
Answer:
vol = 148.9 cm³
Step-by-step explanation:
Vol of a cylinder = π r² h
where r = 3.4 cm
h = 4.1 cm
vol = π * 3.4² * 4.1
vol = 148.9 cm³
