1/10 is equal to 0.10. Multiply their total tables (200) by the percent (10% aka 0.10), and you get 20. Hope this helps.

60 miles per hour
so 156 miles = 156 /60 = 2.6 hours
0.6 x 60 = 36
so 2.6 hours = 2 hours 36 minutes

Kim leaves Rotherham at 7: 30AM
7:30 AM + 2 hours 36 minutes = 10:06 AM

Answer
Kim arrives in London after 10AM

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:

$P(x \le 21) = 0.69146$

Rewrite this equation in slope-intercept form.<br><br> 6x-3y=12

Vanyuwa [196]

Answer:

y = 2x - 4

Step-by-step explanation:

slope intercept form: y = ax + b

6x - 3y = 12

⇔ 6x - 12 = 3y

⇔ y = 2x - 4
