Many electronics follow a failure rate described by an exponential probability density function (PDF). Solar panels are advertis
katovenus [111]

Answer:

The right answer is "0.3193".

Step-by-step explanation:

According to the question,

Mean,

\frac{1}{\lambda}  = 13

\lambda = \frac{1}{13}

As we know,

The cumulative distributive function will be:

⇒ 1-e^{-\lambda x}

hence,

In the first 5 years, the probability of failure will be:

⇒ P(X

                    =1-e^{-(\frac{1}{13} )\times 5}

                    =1-e^(-\frac{5}{13})

                    =1-0.6807

                    =0.3193

Given the side lengths, determine whether thr triangle is acute, right, ovtuse, or not a triangle:
DaniilM [7]

Answer:

1) If sum of the two smaller sides of a triangle is greater than the third longer side, then its a triangle.

<h3>In our case, 20 + 23 > 41. Hence its a triangle .</h3>

Use the side lengths to classify the triangle as acute, right, or obtuse. Compare the square of the length of the longest side with the sum of the squares of the lengths of the two shorter sides

2) Square root of sum of the squares of the two smaller sides is equal to the third longer side, then its a right triangle.

In our case,

√20^2+23^2≈30.4795<41.

<h3>Hence not a right triangle.</h3>

Since the sum of the squares of the two shorter sides is < the square of the longer side, its an obtuse angle triange

Step-by-step explanation:

5x^2-25x=125 solve by completeing the square
IRINA_888 [86]

Answer:

x = 10, -15

Step-by-step explanation:

We can start right away by dividing both sides of our equation by 5 to get the reduced form x^2-5x=25.

To "complete the square," or turn the left side of the equation into something we can factor into a perfect square, it helps to remember that for any binomial x - a:

(x-a)^2=x^2-2ax+a^2

To "complete" our square, we'll need to add an a² to either side of the equation. To find <em>a</em>, we can set 5x = 2ax and solve:

5x=2ax\\5/2=a\\25/4=a^2

Let's add that a² to both sides and simplify!

x^2-5x+\frac{25}{4}=25+\frac{25}{4}\\\\(x-\frac{5}{2})^2=\frac{125}{4}\\\\x-\frac{5}{2}=\pm\sqrt{\frac{125}{4} } \\\\x=\pm\frac{25}{2}-\frac{5}{2}

Now we're ready to solve for both value of x:

x=\frac{25}{2}-\frac{5}{2}=\frac{20}{2} =10\\\\x=-\frac{25}{2}- \frac{5}{2}=-\frac{30}{2} =-15

So our solutions are x = 10 and x = -15
