If a is an integer and a in (-5,30] then the probability that the graph of the function y=x^(2)+2(a+4)x-5a+64 is strictly above the x-axis is

If a is an integer and a in (-5,30] then the probability that the graph of the function y=x^(2)+2(a+4)x-5a+64 is strictly above the x-axis is

The probability that the graph of y=16x^2 +8(a +5)x-7a-5=0, is strictly above the x-axis, If a in [-20,0]

The probability that the graph of y=16x^(2)+8(a+5)x-7a-5=0, is strictly above the x-axis,If a in[-20,0]

The probability that the graph of y=16x^2 +8(a +5)x-7a-5=0, is strictly above the x-axis, If a in [-20,0]

The probability that the graph of y=16x^2 +8(a +5)x-7a-5=0, is strictly above the x-axis, If a in [-20,0]

The probability that the graph of y=16x^2 +8(a +5)x-7a-5=0, is strictly above the x-axis, If a in [-20,0]

The graph of the function y=16x^(2)+8(a+5)x-7a-5 is strictly above the x axis,then 'a' must satisfy the inequality
