Answer:
1/10
Step-by-step explanation:
So first we need to find the probability of the cards, there is 5 cards and one card needs to be chosen, so the probability is 1/5
Then we need to find the probability of the dice, there is 3 even numbers in 1,2,3,4,5,and 6, so the probablity is 3/6 which is also equal to 1/2
Finaly we need to multiply 1/5 with 1/2, which is 1/10
Answer:
it is 78
Step-by-step explanation:
Since and , we can rewrite the right side of the equation as
Using the identity , we can subtract from either side to obtain the identity
substituting that into our previous expression, the right side of our equation simply becomes
We can now write our whole equation as
Adding 2 to both sides:
dividing both sides by 3:
When 0 ≤ x ≤ π, tan x can only be equal to 1 when sin x = cos x, which happens at x = π/4, and it can only be equal to -1 when -sin x = cos x, which happens at x = 3π/4
