Answer:

x = 141°

Step-by-step explanation:

The sum of all the seven angles together would be equivalent to 900°, so I took all the numbers and added it together, receiving 759. I took 759 and subtracted it from 900°, receiving 141°. So the x angle is equivalent to 141°.

Because all heptagons are equivalent to 900°, that is how I knew what the sum of all the angles would be equivalent to.

Suppose human weights are normally distributed with mean 175 and standard deviation 36 pounds. A helicopter is evacuating people

Anuta_ua [19.1K]

Answer:

0.9812

Step-by-step explanation:

Given that human weights are normally distributed with mean 175 and standard deviation 36 pounds

For a sample of 9 people std error of sample would be

$\frac{36}{\sqrt{9} } =12$

Thus we find that sample mean is N(175, 12)

The plane will lift safely if sample average <200 pounds

i.e. Probability that it can safely lift off (i.e., the average weight of a person in the helicopter is less than 200)

= $P(\bar x$

~0.981
