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]`

If a is an integer lying in [-5,30] , then the probability that the graph of 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

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 lying in [-5,30] , then the probability that the probability the graph of y=x^2+2(a+4)x-5a+64 is strictly above the "x-axis" is

If a is an integer lying in [-5,30] , then the probability that the probability the graph of y=x^2+2(a+4)x-5a+64 is strictly above the x-axis is a. 1//6 b. 7//36 c. 2//9 d. 3//5

If a is an integer lying in [-5,30], then the probability that the probability the graph of y=x^(2)+2(a+4)x-5a+64 is strictly above the x-axis is 1/6 b.7/36 c.2/9 d.3/5

The entire graph of y=x^(2)+kx-x+9 is strictly above the X-axis if and only if
