Answer:
3/10.
Step-by-step explanation:
Probability (A blue on the spinner) = 12/20 = 3/5.
Probability( tails) = 1/2.
The probability of a blue and tails = 3/5 * 1/2
= 3/10.
Check the picture below, that's just an example of a parabola opening upwards.
so the cost equation C(b), which is a quadratic with a positive leading term's coefficient, has the graph of a parabola like the one in the picture, so the cost goes down and down and down, reaches the vertex or namely the minimum, and then goes back up.
bearing in mind that the quantity will be on the x-axis and the cost amount is over the y-axis, what are the coordinates of the vertex of this parabola? namely, at what cost for how many bats?
