Answer:
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.
Step-by-step explanation:
An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system
This means that in 2 hours time
400- 201.6= 198.4 mg was used up.
We need only 25 mg in the system
so 400- 25= 375 mg time is needed
time mg
2 hour 198.4
x 375
Using the cross product rule
x= 375*2/198.4
x= 3.780 hrs
Which means 3 hours and (0.78* 60)= 46.8 minutes.
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.

Answer:
The test statistic is and the observed value 1.68
Step-by-step explanation:
We have a large sample size n = 100, the point estimate for the true proportion of overfilled bags p is given by . The test statistic is given by which is distributed as a standard normal variable approximately because we have a large sample. The observed value for the test statistic in this case is
Answer:
Circumference of a circle A =
Area of a circle A = 12081.1 square inches
Step-by-step explanation:
Let denotes radius of circle B.
Circle A has a radius that is five more than twice as long as the radius of circle B.
So,
Radius of circle A =
Diameter of circle = 2 (radius of circle)
So,
Diameter of circle B = 2r
Diameter of circle A =
Sum of the diameters of the circles A and B =
As sum of the diameters of the circles is 88 inches,
inches
Radius of a circle A =
inches
Let R denotes radius of a circle A.
R = 62 inches
Circumference of a circle
Area of a circle square inches
