The probability of rolling a 2 on a number cube is 1/6 . If you were to roll the cube 30 times, you would expect to get a 2 around 5 times ( 1/6 .30= 5) You simulate 30 rolls. How many 2s would make you question your model? A. 5

B. 14

C. 2

D. 8

c. (0.6,-1.4)

step-by-step explanation:

hope this

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
