Answer:
Natural experiment
Explanation:
Natural experiment is the study of empirical, which comprise of the individuals who are exposed to the control as well as the conditions of the experimental , which are determined or evaluated by the nature or through other kinds of factors that are outside the person control.
The procedure of governing the exposures resemble the random experiment. This experiment are not controllable and are the observational studies. So, the event is naturally occurring, then it is an example of the natural experiment.
Answer:
The volume of water needed=0.86 liters
Explanation:
Step 1: Form an equation
The equation can be expressed as follows;
(Ac×Va)+(Wc+Vw)=Fc(Va+Vw)
where;
Ac=initial concentration of antifreeze
Va=volume of antifreeze in liters
Wc=concentration of water
Vw=volume of the water in liters
Fc=final concentration of the antifreeze
This expression can be written as;
(concentration of antifreeze×volume of antifreeze in liters)+(concentration of water×volume of the water)=final concentration of the antifreeze(volume of antifreeze in liters+volume of the water in liters)
In our case;
Ac=45%=45/100=0.45
Va=3 liters
Wc=0
Vw=unknown
Fc=35%=35/100=0.35
Replacing;
(0.45×3)+(0×Vw)=0.35(3+Vw)
1.35=1.05+0.35 Vw
0.35 Vw=1.35-1.05
0.35 Vw=0.30
Vw=0.3/0.35=0.86
Vw=0.86 liters
The volume of water needed=0.86 liters
Answer:
Therefore after 16.26 unit of time, both accounts have same balance.
The both account have $8,834.43.
Explanation:
Formula for continuous compounding :
P(t)= value after t time
= Initial principal
r= rate of interest annually
t=length of time.
Given that, someone invested $5,000 at an interest 3.5% and another one invested $5,250 at an interest 3.2% .
Let after t year the both accounts have same balance.
For the first case,
P= $5,000, r=3.5%=0.035
For the second case,
P= $5,250, r=3.5%=0.032
According to the problem,
Taking ln both sides
Therefore after 16.26 unit of time, both accounts have same balance.
The account balance on that time is
=$8,834.43
The both account have $8,834.43.
