Answer:
the maximum height of the ball is 81.125 feet above the ground. when the ball is at its peak, the ball is 156.25 feet away from home plate.
Step-by-step explanation:
x = d
y = h
to find the x coordinate of the vertex of a parabola, use the equation
x = -b/2a
y = ax^2 + bx+ c
y = – 0.0032x^2 + x + 3
x = -1 / 2 • - 0.0032
x = 156.25
plug x into original equation to find the the y coordinate of the vertex
y = – 0.0032 • (156.25)^2 + (156.25) + 3
y = – 0.0032 • 24414.0625 + 159.25
y = – 78.125 + 159.25
y = 81.125
The probability of both children receiving a tablet is 15%.
We have given that
Age of Children P(Tablet) P(Laptop)
Less than 10 0.3 0.02
10-17 0.5 0.4
<h3>What is the probability?</h3>
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Probability of both children receiving a tablet is
0.3*0.5 = 0.15 = 15%
Therefore, the probability of both children receiving a tablet is 15%
Therefore option b is correct.
