To determine the height of a tree, Maria places a mirror flat on the ground 25 feet from the base. After backing 3.25 feet, she can just see the top of the tree in the mirror. Maria
knows that her eyes are exactly 5 feet above ground level and that the angle between her
eyes, the mirror, and the ground is the same as the angle between the tree-top, the mirror,
and the ground. Which is closest to the height of the tree?

What expression is equivalent to (2x-1)(x-3)?

Match the equivalent expressions. x - 3y + 12 12 - 3y - 2x + x + 2x 3x + 2y - 2x + y + 12 3y + 12 3x + y - 12 4y + 3y + 3x - 6y - 10 - 2 x + 3y + 2x - 3x + 7 + 5 x + 3y + 12 5 + 2y + 7x - 4x + 3y - 17

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
