Task 3: A sequence of transformations was applied to triangle ABC to result in A"B"C". First, ABC was rotated 90 counterclockwise around the
origin to get A'B'C'. Then a translation resulted in A"B"C".
1. What are the coordinates of A'B'C' after the rotation?
(Hint: you need to do the rotation)
A’ ( , )
B'( , )
C'( , )

2. What is the algebraic description of the translation in
this sequence? (Hint: A'B'C' is the preimage: A”B”C” is the image.)
(x, y) → (X —————, y ————-)
(Include both the sign and the number)

The graph shows the prices of different numbers of bushels of corn at a store in the current year. the table shows the prices of different numbers of bushels of corn at the same store in the previous year. previous year number of bushels price of corn (dollars) 2 10 4 20 6 30 8 40 part a: describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value. part b: how many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? show your work.

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 25, a standard deviation of 2.5, and margin of error of 5%
