Two parallel lines are crossed by a transversal.

horizontal and parallel lines b and c are cut by transversal a. at the intersection of lines b and a, the bottom right angle is 50 degrees. at the intersection of lines c and a, the top left angle is y degrees.
what is the value of y?

y = 30
y = 50
y = 110
y = 130

State whether weight is a function of height for the six students and explain. a. yes, height is a function of weight because two students weigh 165 pounds but have different heights. b. no, height is not a function of weight because two students weigh 165 pounds but have different heights. c. yes, weight is a function of height because for each value of height there is one corresponding value of weight. d. no, weight is not a function of height because there is not enough data to determine a function.

The measure of an angle is 117°. what is the measure of a supplementary angle?

The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a mean of $235 and a standard deviation of $20. according to the standard deviation rule, how much did almost all (99.7%) of the students spend on textbooks in a semester?
