Answer:
21.09 ft/s
Step-by-step explanation:
The first step is to create the ratio of speed/time.
Next we must simplify
Next we must convert 14 miles in to feet. There are 5280 feet in a mile.
14 * 5280ft = <u>75,920 feet</u>
Now for hours into seconds.
1 hour = 60 min, 60 min = 3600 seconds
Our new ratio is \frac{75920ft}{3600sec}
simplify.
75920ft / 3600sec = 21.09ft/s
Solution :
Here we can use the Binomial distribution, as there are only two possible outcomes.
The given data:
n = 150
q = 98%
= 0.98
p = probability of not finding relief = 1 - 0.98
= 0.02
A). The number of the individuals who do not find any relief from sinusitis is :
E(x) = np
= 150 x 0.02
= 3
B). The uncertainty of my estimate is =
= 1.716
