Answer:

Step-by-step explanation:
The vertical displacement function is
, where
is measured in meters and
in seconds. Ball hits the ground when
. That is:

Whose roots can be found by using the General Formula for Second-Order Polynomials:

Solutions of this polynomial are:

Only the first root is physically consistent.

A sample size of 60 is required.
We use the formula

We first find the z-score associated with this level of confidence:
Convert 99% to a decimal: 99/100 = 0.99
Subtract from 1: 1-0.99 = 0.01
Divide by 2: 0.01/2 = 0.005
Subtract from 1: 1-0.005 = 0.995
Using a z-table (http://www.z-table.com) we see that this value is equally distant from 2.57 and 2.58; therefore we will use 2.575:
9x$32 + 15 is the total debt.
which would be $303.
