Shreya made the following table where she categorized countries by their region and by average business startup costs, as a percentage of the per capita gross national income (GNI) for a certain year. She decided that high meant greater than or equal to 8% but less than 70%t of the GNI and that very high meant greater than or equal to 70% of the GNI
Find the probability that the country is in the south Asia region, given that Shreya categorized the country's business startup costs as high.

P(south Asia ∣ high)=

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

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
