Answer:
Step-by-step explanation:
(a) The type of study described in the question is referred to as an experimental study.
(b) The treatment group is the group that exercises 2 times a week, whereas the control group is the group that does not exercise.
(c) Yes, the study under consideration makes use of blocking.
The blocking variables are 18-30-year-olds, 31-40-year-olds, and 41-55year olds.
(d) No, the study under consideration did not make use of blinding because the patients know if they are in the group that exercises or the one that doesn’t.
Answer:
After 10 years the cost will be $ 97.52.
Step-by-step explanation:
This problem requires us to calculate the cost of graphing after 10 years if inflation rate is two percent. This can easily be calculated by compounding present value of current cost at the rate of 2%. Detail calculation is given below.
FV= 80 (1+2%)^10
FV = $ 97.52
Answer:
727.5
Step-by-step explanation:
If Jarrod made 3 percent in commissions then y have to find what 97 percent of 750 is
The equation set up would be .97 times 750
750 times .97= 727.5
Answer:
{r|r>0}
Step-by-step explanation:
Pressure is the amount of force exerted on a surface per unit area, P=F/A.
The pressure, in atmospheres (atms), of a liquid on the circular base of a bucket is represented by the composite function PoA(r), where P(A) = 375 / A and A (r) = pi r²
We know that the domain is the set of input values.
Pressure, 
At r = 0, it becomes not defined.
It means that r can be any value that is greater than 0. Hence, the correct option is (c). i.e. {r|r>0}
