Answer:
a. The probability of both balls are blue is .
b. The probability of getting first red and second yellow ball is .
Step-by-step explanation:
It is given that the box contains 14 red balls,12 blue balls,and 9 yellow balls. The total number of balls is
The probability is defined as
Probability of getting red ball =
Probability of getting blue ball =
Probability of getting yellow ball =
It is given that a ball is drawn at random and the color is noted and then put back inside the box. It means first event will not effect the probability of second event.
a.
The probability of both balls are blue is
b.
The probability of getting first red and second yellow ball is
1 - The equation is:
Since it has no variable on exponents and it has a term with x to the second power, this is a quadratic function.
2 - <em>x</em> represents the length of the tomato patch, so if we want the area of the bell pepper patch, we can input x = 8 into the function:
Thus, the area is 16 square feet.
3 - Since the leading coefficient is negative, the vertex of the parabola gives the maximum value for the function.
The <em>x</em> value of the vertex is:
So, in this case:
And to find the value for the area, we need to input that into the function:
Thus, the maximum area is 18 square feet.
4 - The value for the length of the tomato patch is just the corresponding <em>x</em> for this maximum, which we calculated as the vertex <em>x</em>:
Thus, the length of the tomato patch for this maximum value is 6 feet.
