A study of 12,000 able-bodied male students at the University of Illinois found that their times for the mile run were approxima

den301095 [7]

Answer:

$P (y < 6) = \frac{P(y- \mu)}{\sigma} \mu}{\sigma} \\\\=P(z$

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618

Step-by-step explanation:

Normal with mean 6.88 minutes and

a standard deviation of 0.57 minutes.

Choose a student at random from this group and call his time for the mile Y. Find P(Y<6)

$\mu = 6.88$

$\sigma = 0.57$

y ≈ normal (μ, σ)

The z score is the value decreased by the mean divided by the standard deviation

$P (y < 6) = \frac{P(y- \mu)}{\sigma} \mu}{\sigma} \\\\=P(z$

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618

Formula for the surface area of a cylinder, SA = 2ar2 + 2arh. Solve for h.

MakcuM [25]

Answer:

$h=\frac{SA-2\pi r^2}{2\pi r}$

Step-by-step explanation:

The formula for the surface area of a cylinder is:

$SA=2\pi r^2+2\pi rh$

And we want to solve for the height h.

First, subtract $2\pi r^2$ from both sides. This yields:

$2\pi rh=SA-2\pi r^2$

Now, divide both sides by $2\pi r$ . This yields:

$h=\frac{SA-2\pi r^2}{2\pi r}$

And we're done!

Ostrovityanka [42]

Answer:

-13n + 101

Step-by-step explanation:

88, 75, 62, 49. = -13 -13 -13 = -13n + 101 (as 88+13 = 101)
