The angles of elevation to a balloon in the air from two points on level ground are 27 degrees and 45 degrees. If the points are 9 miles apart and the balloon is between the 2 points, in the same vertical plane, approximate, to the nearest tenth of a mile, the height of the balloon above ground.

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

16x^2-16x=5 solve the equation by completing the square

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
