Can someone help me with this. In a school, 30% of the students have hazel eyes. Find the experimental probability that in a group of 4 students, at least one of them has hazel eyes. The problem has been simulated by generating random numbers. The digits 0-9 were used. Let the numbers "6". "7", and "8" represent the 30% of students with hazel eyes. A sample of 20 random numbers is shown.

90%

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
