A mountain climber ascends a mountain to its peak. The peak is 12,740 ft above sea level. The climber then descends 200 ft to me

padilas [110]

Answer:12,450

Step-by-step explanation: Since the climber descends to meet a fellow climber by 200 ft you are going to subtract so the equation is going to be 12,740-200 ft so what does that equal it equals 12,540 ft because it is only subtracting 740-200 ft so 740-200=540 so your answer would more likely be 12,540 not the negative answer.

what is the probability of seeing a sample mean for 21 observations less or equal to the sample mean that we observed

kramer

Answer:

$P(x \le 21) = 0.69146$

Step-by-step explanation:

The missing parameters are:

$n = 64$ --- population

$\mu = 20$ --- population mean

$\sigma = 16$ -- population standard deviation

Required

$P(x \le 21)$

First, calculate the sample standard deviation

$\sigma_x = \frac{\sigma}{\sqrt n}$

$\sigma_x = \frac{16}{\sqrt {64}}$

$\sigma_x = \frac{16}{8}$

$\sigma_x = 2$

Next, calculate the sample mean $\bar_x$

$\bar x = \mu$

So:

$\bar x = 20$

So, we have:

$\sigma_x = 2$

$\bar x = 20$

$x = 21$

Calculate the z score

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

$x = \frac{21 - 20}{2}$

$x = \frac{1}{2}$

$x = 0.50$

So, we have:

$P(x \le 21) = P(z \le 0.50)$

From the z table

$P(z \le 0.50) = 0.69146$

So:

$P(x \le 21) = 0.69146$

The largest solution of x2−x=6 is

trapecia [35]

The left side of the equation subtracts x from 2x.
That means 1x, or just simply x, is left on the left side.
We now have this: x = 6
So, x is 6. Hope this helps!
