The number of cases of a new disease may be modeled by the quadratic regression equation y=-2x^2+40x+8. which of the following is the best prediction for the number of cases after 15 years?

we have been given that number of cases of a new disease can be modeled by the quadratic regression equation .

we need to estimate the number of cases after 15 years.

in order to do so, we will substitute x=15 in the given quadratic regression equation.

therefore, number of cases of a new disease after 15 years are 158.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
