Answer:

20.25 mm

Step-by-step explanation:

Arc length is given by the relation ...

s = rθ

where r is the radius and θ is the central angle in radians.

There are π radians in 180°, so the arc length is ...

s = (5 mm)(232°×π/180°) = 20.25 mm

The arc length is about 20.25 mm.

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.
