On a math test, Stephen missed 3 computation problems and 1 word problem for a total of 9 points off. Brad missed 2 computation problems and 2 word problems for a total of 10 points off. This
relationship can be represented by the system of equations below, where x stands for the point
value of computation problems missed and y stands for the point value of word problems missed.
3x + y = 9
2x + 2y = 10

Suppose m: angle a =77 degrees what is the measure of a complement of a complement of angle a, what is a conclusion you can draw about a complement of a complement of an angle

What is the equivalent fraction for the following fraction using 5 as the multiplier? 1/2

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
