7. A polygon has vertices at F(-5, 2), G(-3, 2), H(-3, 4), |(1,4), K(1, 1), L(4, 1), M(4, -2), N(6, -2), P(6, -3), and
Q(-5, -3). Graph the figure on the coordinate plane.
Then find the area and perimeter of the figure.

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?

Ametal rod needs to be 9 feet and 5.5 inches in length. the sections of the poles being used are each 1 foot and 10.5 inches long. how many 1ft 10.5in sections would be needed to complete the 9ft 5.5in metal rod? and how many inches of material will be left?

Which equation represents the function on the graph?
