Suppose the number of corn kernels on an ear of corn is normally distributed. For a random sample of ears of corn, the confidence interval (858.50, 885.50) is generated. Find the error bound.

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.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
