How many of the 3271 subjects used at least one prescription medication? Round to the nearest integer asneeded.)
Answer:
2902
Step-by-step explanation:
Let the total number of adults within the mentioned age bracket be n=3271
The proportion of adults who used at least one prescription medication be p=88.7%=0.887
The point estimate of population is given by
where x is number of individuals in the sample with the specified characteristics and n is the sample size.
Let x be the adults who used at least one prescription medication
![0.887=\frac {x}{3271}](https://tex.z-dn.net/?f=0.887%3D%5Cfrac%20%7Bx%7D%7B3271%7D)
![x=3271*0.887=2901.377\approx 2902](https://tex.z-dn.net/?f=x%3D3271%2A0.887%3D2901.377%5Capprox%202902)
Slope formula: y2-y1/x2-x1
Part one:
-7-4/-7-(-7)
-11/0
Since the denominator is 0, the slope is undefined.
Part two:
-9-(-9)/2-(-5)
0/7
Since the numerator is 0, the slope is 0.
Best of Luck!
Answer:
27π
Step-by-step explanation:
area of circle = πr^2
= π × 6^2
= 36π
36/4
= 9
36 - 9
= 27π units squared
Answer: 31.5
Step-by-step explanation:
9 is 100% so if you times that by 3 you get 27 and 50% of 9 is 4.5 if you add that to 27 you get 31.5
