Answer:
The correct answare would be 3.54 x 10^22 N
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%.
Neither because neither the cube root or square root of 240 is just one number
Odd numbers are represented as 2n+1 where 2 is a natural number ( negative and possitive whole numbers)
consecutive odd numbers are 2 away from each other so 3 consecutive odd numbers would be
(2n+1),(2n+1+2),(2n+1+2+2)
the all add to -15 so they must all be negative
2n+1+2n+1+2+2n+1+2+2=-15
add like terms
6n+9=-15
subtract 9 from both sides
6n=-24
divide both sides by 6
n=-4
subsitute
first number=2n+1=2(-4)+1=-8+1=-7
second number=2n+1+2=2(-4)+3=-8+3=-5
third number=2n+1+2+2=-8+5=-3
the numbers are -7,-5, -3
the answe ris B
There were 4 number of treatment conditions compared in this experiment for the given degree of freedom.
We have,
df = 3, 36
Now,
We know that,
Degree of freedom (df) = Number of treatments (t) - 1
i.e.
df = t - 1
So,
We have,
df = 3
Now,
Substituting the values,
We get,
3 = t - 1,
i.e.
t = 4
So, number of treatments conditions = 4
Hence we can say that there were 4 number of treatment conditions compared in this experiment for the given degree of freedom.
