Answer:
See explanation below.
Step-by-step explanation:
Let's say,
x = number of tokens required to play one game of ping pong
y = number of token required play one game of pinball
Using the data given, the system of equations are:
Solving the system of equations using substitution method will give us:
So, one game of ping pong required 1 token, whereas one game of pinball required 4 tokens.
X/3 +10=15
-10 -10
x/3 =5
so the x will be 15 because if you multiply 3x5 = 15
Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability blue or red marble: 7/10
Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability non-blue or red marble: 3/10
10. 6.8 this is the nearest tenth
13. 3.7 this is the nearest tenth
16. 6.7 this is the nearest tenth
Answer:At 95% confidence interval, the lower end is 64.306 and the upper end is 64.614
At 98% confidence interval, the lower end is 64.268 and the upper end is 64.652
