Which function represents a function with zeros at -3, -1, 0, and 6? A. y = (x − 6)(x + 1)(x + 3)
B. y = x(x − 3)(x − 1)(x + 6)
C. y = x(x − 6)(x + 1)(x + 3)
D. y = (x − 3)(x − 1)(x + 6)

C. y = x(x − 6)(x + 1)(x + 3)

I hope this helps.

The percent of times that are at least 14.3 seconds is approximately 16%.

Step-by-step explanation:

Let X denote the time for running the 100-yard dash.

It is provided that the times are very closely approximated by a normal curve.

So, the random variable X follows a normal distribution with a mean time of 15.2 seconds and with a standard deviation of 0.9 seconds.

Compute the probability of times that are at least 14.3 seconds as follows:

*Use a z-table.

Thus, the percent of times that are at least 14.3 seconds is approximately 16%.
