Answer:
3 is the correct answer (see explanations for each possible choice)
Step-by-step explanation:
1 cannot be right because 3 times smaller than 9 would be 3 as 1/3*9=3
2 cannot be right because 3 less than 9 is 9-3=6
3 is right because 3 times as much as 9 is 9*3=27
4 cannot be right because 3 more than 9 is 3+9=12
3s + h = $47
7s + 2h= $107
3s + h =$47
3s - 3s + h = $47 -3s
h = $47 - 3s
7s + 2($47 - 3s) = $107
7s + 94 -6s = 107
s + 94 = 107
s +94 -94 = 107- 94
s = 13
3(13) + h = $47
39 + h =$47
39 -39 + h= $47-39
h = 8
Check
7s + 2h= $107
7(13) + 2(8)= $107
91 + 16= 107
107 = 107
She earns $13 per suit sold and $8 per pair of shoes sold.
Answer:
I think this is the answer
Step-by-step explanation:
2:3=10:15
12:15=4:5
1:5=5:25
15:30=1:2
The data collected from the actual game experiment is:
Win: 8 times
Lose: 40 times
Total trials: 48 times
Therefore, the probability that you will win when you play this game is:
WIN = 8/48
= 1/6 or 0.1667 = 16.67% chance of winning
LOSE = 40/48
= 5/6 or 0.8333 = 83.33% chance of losing.
