An athletics coach states that the distribution of player run times (in seconds) for a 100-meter dash is normally distributed wi

Elza [17]

Answer:

$P(X$

And we can find this probability using the normal standard distribution table and we got:

$P(z$

And the percentage faster than 13.28 seconds would be 91.9%

Step-by-step explanation:

Let X the random variable that represent the runtimes of a population, and for this case we know the distribution for X is given by:

$X \sim N(13,0.2)$

Where $\mu=13$ and $\sigma=0.2$

We want to find this probability:

$P(X$

And we can use the z score formula given by:

$z=\frac{x-\mu}{\sigma}$

Using this formula we have:

$P(X$

And we can find this probability using the normal standard distribution table and we got:

$P(z$

And the percentage faster than 13.28 seconds would be 91.9%

The circle below is centered at the point (-1,3) and has a radius of length 4

Snowcat [4.5K]

(x-h)^2 + (y-k)^2 = r^2 where h & k are the x,y values of the center point

(x + 1)^2 + (y-3)^2 = 4^2
<span>(x + 1)^2 + (y-3)^2 = 16</span>
