Answer:
how would i know the answer
Step-by-step explanation:
Answer:
The answer is 2
Step-by-step explanation:
sin60°+ 2 tan45° - cos30°
sin60° = √3/2
2 tan45° = 1
cos30° = √3/2
sin60°+ 2 tan45° - cos30°
√3/2 + 2(1) - √3/2
√3/2 - √3/2 + 2(1)
0 + 2 = 2
Thus, The answer is 2

Answer:
C. 17 miles
Step-by-step explanation:
Divide 68 by 4 since it is a fourth of an hour
Part 1:
You have the correct answer. You multiply the probability of getting red (6/15) by the probailitiy of getting red (6/15) to get 36/225 which reduces to 4/25
--------------------------------
Part 2:
This is also correct. Nice work. You multiply the probability of getting black (9/15) with the probability of getting red (6/15) to get 54/225 = 6/25
--------------------------------
Part 3:
The probability of picking a black checker is 9/15. If a replacement is made, then the probability of picking another black checker is also 9/15. So,
(9/15)*(9/15) = 81/225 = 9/25
Answer: 9/25
--------------------------------
Part 4:
The probability of rolling a 6 is 1/6. The probability of rolling a 3 is 1/6 as well. This is because there is only one side with this label out of 6 total. Multiply the probabilities
(1/6)*(1/6) = 1/36
Answer: 1/36
--------------------------------
Part 5:
It is impossible to roll a 7 on the six sided cube because the highest number is 6. Therefore the overall probability is 0
Answer: 0
--------------------------------
Part 6:
There are 3 outcomes we want (rolling a 1,2, or 3) out of 6 total. So the probability of rolling a 1,2 or 3 is 3/6 = 1/2. Similarly, the probability of rolling a 4, 5 or 6 is 3/6 = 1/2 as well.
Multiplying the probabilities gives
(1/2)*(1/2) = 1/4
Answer: 1/4
