The answer is 20 because if you divide 15:20 by 5, you get 3:4. hope this helps!
The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r
Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.
π*diameter=15*π
We can divide π from both sides.
diameter=15
Hope this helped!
Answer:
The error bound is of 13.5 corn kernels.
Step-by-step explanation:
Any confidence interval has a lower bound and an upper bound. The error bound is the difference between the values of those two bounds, divided by 2.
In this problem, we have that:
Lower bound: 858.50
Upper bound: 885.50
Error bound: (885.50-858.50)/2 = 13.5
The error bound is of 13.5 corn kernels.
