What is the sequence of transformations that maps ∆ ABC to ∆ A'B'C step one options:
- translate 3 units up
- reflect across the x-axis
- reflect across the y-axis
- rotate 90 degrees counterclockwise about the origin

step two options:
- translate 4 units left
- reflect across the y-axis
- rotate 90 degrees clockwise about the origin
- rotate 90 degrees counterclockwise about the origin

To describe a sequence of transformations that maps triangle abc onto triangle a"b"c", a student starts with a reflection over the x-axis.how should the student complete the sequence of transformations to map triangle abc onto triangle a"b"c"? plz

7. if the value of x varies directly with the value of y, and x = 3 when y = 21. what is the valu y, and x = 3 when y = 21. what is the value of x when y = 105?

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.
