Answer:
1) B 1/4
2) C 36
3) C 4
Step-by-step explanation:
1) 1/2 chance for tails on both the first and second flips
1/2•1/2 = 1/4
2) 8/10 marbles are white.
as the marble is always replaced, the chances never change.
0.8(45) = 36
3) there are 6 sides to a cube but only one even number less than four (2), so the chances are 1/6
1/6•24 = 4

Answer:
The third choice down
Step-by-step explanation:
Plotting the point (-2, 9) has us in QII. We connect the point to the origin and then drop the altitude to the negative x-axis, creating a right triangle. The side adjacent to the reference angle theta is |-2| and the alltitude (height) is 9. The sin of the angle is found in the side opposite the angle (got it as 9) over the hypotenuse (don't have it). We solve for the hypotenuse using Pythagorean's Theorem:
so
and
Now we can find the sin of theta:
We have to rationalize the denominator now. Multiply the fraction by
Doing that gives us the final
third choice from the top
Answer:
the distance from zero and it has to be positive so it will be 15
