Answer:
3. 1 / 4
4. 1 / 28
5. Idk sry.
6. 35
7. 28
8. 1 / 32
9. Idk sry.
10. 48
Step-by-step explanation:
3. So there are 16 marbles in the bag, so if you take a green, it's 1/2, and then another, 1/2.
1/2 * 1/2 = 1/4
4. So there are 16 marbles again. One red would be 5 / 16, one blue would be 1 / 5, and one green would be 4 / 7
5 / 16 * 1 / 5 * 4 / 7 = 20 / 560 = 1 / 28
5. Pick 7 out of 7, the formula is C = n! / r!(n - r)!
n = 7
r = 7
Idk sry
6. Pick 3 out of 7
n = 7
r = 3
C = 7! / 3!(7 - 3)!
C = 5040 / 6 * 24
C = 35
7. Pick 2 out of 8
n = 8
r = 2
8! / 2!(8 - 2)!
40320 / 2 * 720
C = 28
8. You have 2 tails and 3 heads.
Say you get the first two tails.
That's 1 / 4
Then you have to get the rest heads.
1 / 8
1 / 4 * 1 / 8 = 1 / 32
9. Idk sry.
10. Multiples of 3: 33
Multiples of 5: 21
Multiples of 15: 6
33 + 21 - 6 = 48
Greetings!
What is parallel line and perpendicular line? Give real life example with neat figure.
- Parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel.
- Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it.
Answer:
They have the same amount of tokens after t = 7.6 hours
Step-by-step explanation:
Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour. So, the number of token he losses after t hours is 3 token per hour × t hours = 3t. Thus, the number of tokens left after t hours is T = 50 - 3t
Since Gibson initially has 12 tokens and finds two tokens on the ground per hour, he gains 2 tokens per hour. So, the number of token he gains after t hours is 2 token per hour × t hours = 2t. Thus, the number of tokens he has after t hours is T' = 12 + 2t
To calculate the time t when they will have the same tokens, T must be equal to T', that is T = T'.
So, 50 - 3t = 12 + 2t
collecting like terms, we have
50 - 12 = 3t + 2t
38 = 5t
dividing both sides by 5, we have
t = 38/5
t = 7.6 hours
So, they have the same amount of tokens after t = 7.6 hours
