The probability that the major of one student that is selected at random is engineering can be calculated by the total number of engineering major divided by the total number of students
p = engineering / total students
p = 300 / ( 300 + 700 + 500)
p = 0.2 is the probability of the major of one student is engineering
11. 50*17 answer divided by $356
12.$21*3 then get the answer
13. Do $20*15
14.$2.20*10
15.5*15 then get the answer
Hope I helped
Since w is 22, you substitute w with 22. 30(22) + 70 equals 730 calories
Neither ! X= -9/4 and Y=9
Sometimes true, depends on d. ex: -8 + -8 is negative, but -8 + 9 is positive
