Suppose in Problem 3 that we wished to design a test so that if the pH were really equal to 8.20 this conclusion will be reached with probability equal to 0.95. On the other hand, if the pH differs from 8.20 by 0.03 (in either direction), we want the probability of picking up such a difference to exceed 0.95. What is the test procedure that should be used and what is the required sample size

The lengths of all sides of a triangle are integers when measured in decimeters. one of the sides has length of 1 dm and another of 3 dm. find the perimeter of the triangle.'

1. find the area of the unshaded square 2. find the area of the large square 3. what is the area of the frame represented by the shaded region show

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
