Answer: 176m
Step-by-step explanation:
First we have to convert the meters in the scale to millimeters
4m = 4*1000mm
Now we got the scale 11:4000
11x = 4000 * 484
x= (4000*484)/11
x = 4000 * 44
x = 176000mm = 176m
B. 6 5 / 7
C. 6 3 / 4
D. 67 / 5

P( skiſ does not wake board)
Answer:
10% of the students ski and do not wake board
Step-by-step explanation:
The total number of students is 120. 28 students ski while 52 students wake board. 16 of the students ski and wake board.
Let S represent students who ski and W represent those who wake board also W' represent those who do not wake board.
Therefore:
S = 28
W = 52
n = total number of student = 120
S ∩ W = those who ski and wake board = 16
Those who ski and do not wake board = S ∩ W' = S - (S ∩ W) = 28 - 16 = 12
Probability of those who ski and do not wake board = (S ∩ W') / n = 12 / 120 = 0.1 = 10%
10% of the students ski and do not wake board
