the hypotenuse of a right leg triangle is 12 centimeters, and the shorter leg is 6 centimeters. Find the length of the other leg

1 answer:

5 0

Well that's quite easy. There is a short cut. So 12 divided by 2 is 4. Then 6 divided by 2 is 3. There is a thing called a Pythagorean Triple. And the first one is 3,4 (which is the missing side) and 5. That is the most commonly used set and so are the number's multiples. Therefore the missing leg's length is 4 centimeters.

Answer:

The probability that the proportion of books checked out in a sample of 412 books would differ from the population proportion by less than 4% is P=0.9255.

Step-by-step explanation:

The population's proportion is $\pi=0.29$

If we take a sample of 412 books (n=412), we have a standard deviation of the sampling distribution of:

$\sigma_M=\sqrt{\frac{\pi(1-\pi)}{n}}=\sqrt{\frac{0.29*0.71}{412}}=\sqrt{0.0005} =0.0224$

We have to calculate the probabilty that the sample proportion will be between 0.25 and 0.33.

$z_1=(0.25-0.29)/0.0224=-0.04/0.0224=-1.7857\\\\z_2=1.7857\\\\\\P(0.25$
