Answer:
S(t) = 600*0.9^t
Step-by-step explanation:
At the beginning (t = 0) the sample has 600 grams. After 1 millennium from today (t = 1) the mass will be: 600 - 600*0.1 = 600*0.9. After 2 millennium from today (t = 2) the mass will be the 90% of the mass in the previous millenium, that is: 600*0.9*0.9 = 600*0.9^2. Analogously, at time = 3, sample's mass will be: 600*0.9^2*0.9 = 600*0.9^3. In a table format, that is
t m
0 600
1 600 - 600*0.1 = 600*0.9
2 600*0.9*0.9 = 600*0.9^2
3 600*0.9^2*0.9 = 600*0.9^3
Therefore, sample's mass in grams, S(t), where t refers to millennia from today is computed as follows: S(t) = 600*0.9^t
Answer: Fatigue level
Step-by-step explanation: Dependent variable refers to the measured or observed variable in an experimental study. The dependent variable is the variable observed or studied in other to make assessment of effects which occurs by varying the independent variable. In the study described above, the self reported fatigue level is measured or recorded while subjecting the participant to varying conditions of noise; white noise and normal noise level, which are the independent variables. The dependent variable, fatigue level is the variable being measured in the experiment by subjecting the participants to the two different traet ment conditions which are the independent variables.
No it depends on the sum of the two numbers
Answer:
$108
Step-by-step explanation:
The computation of the total profit is shown below:
Given that
1 box = $12
18 boxes = 12×18 = $216
So
Total = 18×65 = 1170 pens
Now Cost price, Cp = $216
Also,
3 = $1
So,
= 378 ÷ 3
= $126
Now
= 1170-378
= 792 pens remaining
4 = $1
So,
792
= 792 ÷ 4
= $198
Now
Total selling price, sp = 126+198 = $324
So finally
Profit = Sp - Cp
= $324 - $216
= $108
Answer:
Option B: 1/4(n - 64)
Step-by-step explanation:
As given that:
= 1/4n - 16
By taking 1/4 common: 4 will get multiplied by 16
As 16*4 = 64 so,
The expression would become:
=1/4(n -64)
