If the path of the t-shirt is represented by a parabola, which function could be used to represent the height of the t-shirt as a function of time, t, in seconds?

Average acceleration: i have no idea how to do this.

Is this a polynomial function? i need to know asap

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
