Answer:
B. Choose a random sample of people from the local area and random times throughout the day and measure their blood sugar using both the wristband and standard blood test.
Step-by-step explanation:
This is because here we are using a sample that is not limited to one time(like lunch time as option 1), the blood reading are of the same person(unlike option 3) and is not biased due to selective sample collection(like patients in a hospital who normally will show a greater range of results)
Answer:
between which 2 times is the ball higher than 48 meters
Step-by-step explanation:
If the diameter of the smaller circle is 3.5cm, that means the radius is 1.75cm.
The area of the smaller circle is π × 1.75², which is ≈ 9.62112750162.
The diameter of the larger circle is 12.5 cm, so the radius would be half that, which is 6.25cm. The area of the larger circle would be π × 6.25², which is ≈ 122.718463031.
So now that we know the area of the larger circle and the smaller circle, we can find the area of the shaded region by subtracting the area of the smaller circle from the area of the larger circle, which is basically just 122.718463031 - 9.62112750162, which is = 113.097336. The closest answer here is 113.04, hence the answer is 113.04cm².
