The total number of marbles in the bag is 1 + 4 + 3 = 8
The probability of drawing one marble and getting blue is 4/8 = 1/2
Since marble is put back and he draws again, the probability will again be 1/2
The total probability = 1/2 * 1/2 = 1/4.
1/4 <<<<Answer

so... if you notice, the vertex is at h,k and that'd be the origin, 0,0
so...since the directrix is "p" units from the vertex, so it'd be 2 units from 0,0
now, the parabola has an equation with a positive leading term's coefficient, namely the 1/8 is positive, thus, the parabola is opening upwards, and the directrix is "outside" the parabola, so is below the vertex
that puts the directrix 2 units below 0,0
y = -2
Well, at the END of 100, none excluding post decimal zeroes, including them there are infinite. If you meant how many zeroes inside 100, 2 then.
For the function 5x, the range is the value of f(x) which is five times the x and the domain is the value of x which can be the ratio of f(x) and 5. For the second function which is g(x) = 5, the range is 5 all through out the graph while the domain is infinity.
Solve for v by simplifying both sides of the equation, then isolating the variable.
v = -1
