Answer:
Step-by-step explanation:
principal amount by women for savings = $ 580
duration = 1 year and rate of interest on it = 6 .1/2 % = 13/200
now amount of interest she'll be earning = $580 x 1 x 13 /200 = $37.7
thats 37 dollar 70 cents
Answer:
Evidence of an increased risk of lung cancer associated with cigarette smoking was sought by Doll and Hill. In one study, 649 lung cancer cases were matched by age, and gender to 649 controls; 647 of the cases and 622 of the control had a history of smoking cigarettes.a.Name the type of study. Case control studyb.Create the appropriate 2X2 table for the study. (2 points)Lung CancerControlsSmokers647622Nonsmokers227Total649649c.Calculate the appropriate measure of association for the study. (4 points)The odds ratio: Cases = 647 / 2 = 323.5The odds ratio: Control = 622 / 27 = 23.03The odds ratio = 23.03 / 323.5 = 14.04 d.Interpret the results. (2 points)Smokers are 14 times more likely to develop lung cancer than non-smokers.

Answer:
Option C. exponential decay function
Step-by-step explanation:
In this problem we have a exponential function of the form

where
y ---> is the money that is in the bank
x ----> number of days
a ---> is the initial value or y-intercept
b is the base of the exponential function
r ---> is the rate of change
b=(1+r)
In this problem we have that
Each day 1/2 of the money that is in bank value is removed
so
---> is negative because is a decreasing function
The value of b is equal to


The value of b is less than 1
b<1
That means -----> Is a exponential decay function

Step-by-step explanation:
Ok first you have to convert 100 miles to feet.
A mile is 5,280 feet
100x5,280
528,000
Thats how much feet per hour. Now we need to find feet per second. So lets divide 528,000 by 60
528,000/60
8,800
Now we know 8,800 is how much feet per minute now we divide it once more by 60 to find feet per second.
8,800/60
146 2/3
So your answer is 146 2/3ft/sec
