Births are approximately Uniformly distributed between the 52 weeks of the year. They can be said to follow a Uniform distributi

Kaylis [27]

Answer:

a) 27

b) 15

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean of the uniform distribution is:

$M = \frac{a + b}{2}$

The variance of the uniform distribution is given by:

$V = \frac{(b-a)^{2}}{12}$

The standard deviation is the square root of the variance.

They can be said to follow a Uniform distribution from 1 to 53

This means that $a = 1, b = 53$

a. The mean of this distribution is

$M = \frac{a + b}{2} = \frac{1 + 53}{2} = 27$

b. The standard deviation is:

$s = \sqrt{V} = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(53-1)^{2}}{12}} = 15$

Persuade Mr. Zorn whether the numbers 12, 16, and 20 make a right triangle or not. Make sure to state reasons for or against you

Darya [45]

Answer:

Yes!

Step-by-step explanation:

In Pythagorean Triples, the two legs always have to add up to be a greater number than the hypotenuse. In this case, 12 and 16 are the legs and 20 is the hypotenuse. The sum of 12 and 16 is 28. That is more than 20, so 12, 16 and 20 make a right triangle. I hope this helps you!
