Acellus Find the expected value of a random variable x having the following probability distribution. 0 1 2 3 4 5 Probability 1/

barxatty [35]

Answer:

"2.25" is the right answer.

Step-by-step explanation:

According to the question,

The expected value will be:

= $\sum_{i=1}^{n} x_i P(X = x_i)$

= $0\times \frac{1}{8}+1\times \frac{1}{4}+2\times \frac{3}{16}+3\times \frac{1}{4}+4\times \frac{1}{6}+5\times \frac{1}{8}$

= $0+\frac{1}{4}+\frac{3}{8} +\frac{3}{4}+\frac{1}{4} +\frac{5}{8}$

= $\frac{1}{4} +\frac{8}{8} +\frac{4}{4}$

= $\frac{1}{4} +1+1$

= $0.25+2$

= $2.25$

Thus the above is the right approach.

Which of the following could be points on the unit circle?

storchak [24]

Answer:

A and D

Step-by-step explanation:

Unit circle is a circle described by the equation

x^2 + y^2 = 1

We can try each pair and check

A. $(\frac{6}{7})^2 + (\frac{\sqrt{13}}{7})^2 = \frac{36}{49} + \frac{13}{49} = \frac{49}{49} = 1$

B. $(\frac{4}{3})^2 + (\frac{4}{5})^2 > (\frac{4}{3})^2 > 1$

C. $(\frac{1}{3})^2 + (\frac{2}{3})^2 = \frac{1}{9} + \frac{4}{9} = \frac{5}{9} < 1$

D. $(\frac{5}{13})^2 + (\frac{12}{13})^2 = \frac{25}{169} + \frac{144}{169} = \frac{169}{169} = 1$
