Answer: $14,450.00

Step-by-step explanation:

$10,000 + 8.9% (5)

= $10,000 + $890 (5)

= $10,000 + $4450

= $14,450

Answer:

36.58% probability that one of the devices fail

Step-by-step explanation:

For each device, there are only two possible outcomes. Either it fails, or it does not fail. The probability of a device failling is independent of other devices. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

A total of 15 devices will be used.

This means that $n = 15$

Assume that each device has a probability of 0.05 of failure during the course of the monitoring period.

This means that $p = 0.05$

What is the probability that one of the devices fail?

This is $P(X = 1)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 1) = C_{15,1}.(0.05)^{1}.(0.95)^{14} = 0.3658$

36.58% probability that one of the devices fail

Find the exact value of: sin13pi/8

Vikentia [17]

Sin(13π/8) , is in quadrant IV so the angle will be negative, find the reference angle.

sin(13π/8) = -sin(16π/8 - 13π/8) = -sin(3π/8) = -cos(4π/8 - 3π/8) = - cos(π/8). 

Use half angle formula for cos(x): 
cos²(x/2) = (cos(x) + 1) / 2 
Let x = π/4 
cos²(π/8) = (cos(π/4) + 1) / 2 
cos²(π/8) = (√(2) / 2 + 1) / 2 
cos(π/8) = √(√(2) / 4 + 1/2) 

-cos(π/8) = -√((√(2) + 2) / 4)
