Bob is standing 25 feet from a lamppost that is to his left and 30 feet from a lamppost that is to his right. the distance between the two lampposts is 20 feet. what is the measure of the angle formed from the line from each lamppost to bob? approximate to the nearest degree. 1. 202 = 252 + 302 ? 2(25)(30)cos(a) 2. 400 = 625 + 900 ? (1500)cos(a) 3. 400 = 1525 ? (1500)cos(a) 4. ? 1125 = ? (1500)cos(a) degrees

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
