Question

Questions 5-8 please!! Thanks!!

Answer 1

5. (1 1/2) /3 = 
    (3/2) / (3) =
    3/2 * 1/3 =
    3/6 reduces to 1/2

6. 1 1/4 * 3/5 =
    5/4 * 3/5 =
    15/20 reduces to 3/4

7. mean of 6 and median of 8....
    (8 + 8 + 8 + x) / 4 = 6
    (24 + x) / 4 = 6
    24 + x = 24
    x = 24 - 24
    x = 0

ur numbers are : 0,8,8,8.....has a median of 8 and a mean of 6

8. (a) probability of tails is 30/100 reduces to 3/10
    (b) 70/100 = x/300
          cross multiply
          (100)(x) = (300)(70)
           100x = 21000
           x = 21000/100
           x = 210 heads would be expected
