Answers
Given : the number of cases of a new disease can be modeled by the quadratic regression equation y=-2x²+36x+6
To find : Which is the best prediction for the number of new cases in year 15? A. 194 B. 96 C. 328 D. 614
Solution:
y = -2x²+36x+6
to estimate prediction for the number of cases in Year 15
we just need to put x = 15
as x represent the year
y will represent the number of New cases in that year
y = - 2(15)² + 36(15) + 6
=> y = -2(225) + 540 + 6
=> y = -450 + 546
=> y = 96
96 is the best prediction for the number of new cases in year 15
