Quadrilateral PQRS is located at P (β4, 1), Q (β2, 3), R (1, 1), and S (β2, β2). Russell and Jamie have both classified PQRS differently. Examine their proofs. Who is correct?
Russell Jamie
PQRS is a parallelogram because both pairs of opposite sides are parallel
Segment PQ
P (β4, 1) and Q (β2, 3)
m equals 3 minus 1 over negative 2 plus 4 equals 2 over 2 equals 1
Segment SR
S (β2, β2) and R (1, 1)
m equals 1 plus 2 over 1 plus 2 equals 3 over 3 equals 1
Segment PS
P (β4, 1) and S (β2, β2)
m equals negative 2 minus 1 over negative 2 plus 4 equals negative 3 over 2
Segment QR
Q (β2, 3) and R (1, 1)
m equals 1 minus 3 over 1 plus 2 equals negative 2 over 3
Segments PQ and SR are parallel, and segments PS and QR are parallel. PQRS is a parallelogram because both pairs of opposite sides are congruent
Segment PQ
P (β4, 1) and Q (β2, 3)
d equals the square root of the quantity negative 2 plus 4 all squared plus 3 minus 1 all squared equals the square root of the quantity 4 plus 4 equals the square root of 8 equals 2 times the square root of 2
Segment SR
S (β2, β2) and R (1, 1)
d equals the square root of the quantity 1 plus 2 all squared plus 1 plus 2 all squared equals the square root of the quantity 9 plus 9 equals the square root of 18 equals 3 times the square root of 2
Segment PS
P (β4, 1) and S (β2, β2)
d equals the square root of the quantity negative 2 plus 4 all squared plus negative 2 minus 1 all squared equals the square root of the quantity 4 plus 9 equals the square root of 13
Segment QR
Q (β2, 3) and R (1, 1)
d equals the square root of the quantity 1 plus 2 all squared plus 1 minus 3 all squared equals the square root of the quantity 9 plus 4 equals the square root of 13
Segments PQ and SR are congruent, and segments PS and QR are congruent.

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
