The following quadratic regression equation gives us an estimate of n, which is the number of days the AQI exceeded 100 a
particular year. We will use this equation to estimate the number of days the AQI was over 100 in the year 1995.
n-1.762 - 13.321+ 41.00
(Lett represent the number of years since 1990. Therefore, t = 0 corresponds to the year 1990. For the estimate of n, round to the
nearest whole day.)
18 days
b. 24 days
c. 182 days
d. 72 days

The sum of two numbers is 86, and their difference is 20. find the two numbers

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.
