The rule T1, -4 CompositionRO, 180°(x, y) is applied to rectangle KLMN.
On a coordinate plane, 5 rectangles are shown. Rectangle K L M N has points (3, negative 4), (3, negative 1), (5, negative 1), (5, negative 4). Rectangle 1 has points (negative 4, 6), (negative 4, 4), (negative 1, 4), (negative 1, 6). Rectangle 2 has points (0, 0), (negative 2, 0), (negative 2, 3), (0, 3). Rectangle 3 has points (negative 2, 0), (negative 4, 0), (negative 2, negative 3), (negative (4, negative 3). Rectangle 4 has points (1, 0), (4, 0), (1, 2), (4, 2).
Which rectangle shows the final image?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3
