Answer:
The probability is 3/5
Step-by-step explanation:
Given,
Sample space, S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10},
⇒ n(S) = 10,
Odd numbers less than 7 = 1, 2, 3, 4, 5 and 6
i.e. E = {1, 2, 3, 4, 5, 6}
⇒ n(E) = 6,
So, the probability of the event E,
Answer:
Every hour, the medicine concentration decays by a factor of 4%.
Step-by-step explanation:
The relationship between the elapsed time, <em>t</em>, in minutes, since the medicine was ingested, and its concentration in the bloodstream, <em>C</em> (<em>t</em>), is:
The decay function is:
Here,
<em>y</em> = final amount
<em>a </em>= initial amount
<em>r</em> = decay rate
<em>t</em> = time
From the provided expression the decay rate is:
Thus, every hour, the medicine concentration decays by a factor of 4%.
