Answer:

Yes

Step-by-step explanation:

Using the Pythagorean theorem, you would square 8, 15, and 17. 8^2 is 64. 15^2 is 225. If you add those, you get 289. Now, 17^2 is 289. Because 289=289, it is a square triangle.

svp [43]

Answer:

$m\angle L = 111\degree \\m\angle M = 69\degree$

Step-by-step explanation:

Since, angle L and angle M are supplementary.

$\therefore m\angle L + m\angle M= 180\degree \\ \therefore \: 12x + 45 + 18x - 30 = 180 \degree \\ \therefore \: 30x + 15= 180 \degree\\ \therefore \: 30x= 180 \degree - 15 \degree\\ \therefore \: 30x= 165 \degree \\ x = \frac{165 \degree}{30} \\ x = 5.5 \degree \\ \\ m\angle L = 12x + 45 \\ m\angle L = 12 \times 5.5 + 45 \\ m\angle L = 66 + 45 \\ \huge \red{ \boxed{ m\angle L = 111 \degree}} \\ \\ m\angle M=18x - 30 \\ m\angle M=18 \times 5.5 - 30 \\ m\angle M=99 - 30 \\ \huge \purple{ \boxed{ m\angle M=69 \degree}} \\$

Majesty Video Production Inc. wants the mean length of its advertisements to be 24 seconds. Assume the distribution of ad length

oksano4ka [1.4K]

Answer:

It is going to be bell-shaped(normally distributed), with mean $\mu = 24$ and standard deviation $s = \frac{2}{\sqrt{15}} = 0.5164$ .

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$ .

What can we say about the shape of the distribution of the sample mean time?

It is going to be bell-shaped(normally distributed), with mean $\mu = 24$ and standard deviation $s = \frac{2}{\sqrt{15}} = 0.5164$ .
