Answer:
To Find the median you order them from least to greates or vice versa, therefore 4,5,6,6,12,17,19 the median would be 6 because it is in the middle, the mean would be adding all of them and dividing by 7 because there are 7 variables. therefore the mean is 9.85 or you can round to 10 / 9.9
0.75(3.5a -6b)
= 0.75* (3.5a) -0.75* (6b) (distributive property)
= 2.625a -4.5b
The final answer is 2.625a -4.5b~
The answer is a
40 - 4 equals 36 divided by three equals 12
12 times 3 + 4 = 40
50- 2 = 48 divided by 4 = 12
12 times 4 + 2 = 50
