Answer: -pi/4 and 3pi/4
Step-by-step explanation:
Whenever you're given an inverse trig function like this, think "tangent of what gives me -1?" There are multiple ways in which you can solve this; knowing how tangent work, guess checking sin/cos to get -1, or using a calculator. The only way tangent can be an integer is if the sine and cosine of the angle are equal.
The only spots on the pi circle where this happens is pi/4, 3pi/4, 5pi/4, and 7pi/4. Answers B and D are correct
A balloon is a sphere and the volume of a sphere is V=4/3 π.R³
V= 4/3.π.(6³) = 4/3.π.216 = 288π unit³ or ≈ 905 unit³
The correct answer to this question is this one: "C. One-Fourth."
The total possibility that the head and even no on dice appears is 3.
The total possible choices are 12 {head ->(1,2,3,4,5,6) & tail->(1,2,3,4,5,6)}. so the probability is 3/12= 1/4.
These are independent events so the total probability will be the product of the individual probabilities:
