Josephine owns a diner that is open every day for breakfast, lunch, and dinner. She offers a regular menu and a menu with daily specials. She wanted to estimate the percentage of her customers who order specials. She selected a random sample of 50 customers who had lunch at her diner during a three-month period. She determined that 28% of these customers ordered from the menu with specials.
Which statement about Josephine's sample is true?

A. The sample is the percentage of customers who ordered daily specials.

B. The sample might not be representative of the population because it only included lunch customers.

C. The sample shows that exactly 28% of Josephine's customers ordered daily specials.

D. No generalizations can be made from this sample, because the sample size of 50 is too small.

B. The sample might not be representative of the population because it only included lunch customers.

The coordinates of a quadrilateral are shown:

point J (−4.5, 3)
point K (−1.2, 3)
point L (−1.2, 8.7)
point M (−4.5, 8.7)

Brenda claims that quadrilateral JKLM is a square.

Show or explain why Brenda is not correct.

Sample Student Response:

In a square, the lengths of all four sides are the same. If quadrilateral JKLM is a square, all four of its side lengths would be the same. Since the y-coordinates are the same in points J and K, the side length of JK is the positive difference between the x-coordinates of each point. So, JK = |−4.5 − (−1.2)| = |−4.5 + 1.2| =|−3.3| = 3.3 units. Similarly, the side length of KL is the positive difference between the y-coordinates of each point. So, KL = |3 − 8.7| = |−5.7| = 5.7 units.

The lengths of two sides of the quadrilateral are not equal, so quadrilateral JKLM is not a square.
