What figure is comprised of two rays that share a common endpoint called a vertex?

1 answer:

4 0

<span>The answer is B. Angle. In order to form an angle two rays must meet at an endpoint called a vertex and lie in a plane. Appropriately, the word angle comes from the Greek word for corner. Generally speaking there are three types of angles; acute, obtuse, and straight angles.</span>

there has to be at least one operating path. Once a component fails on a path, that path is no longer operating. The reliability

Eva8 [605]

Answer:

$R = P(R_1) P(R_2|R_1) P(R_3|R_2)*....*P(R_n |R_1,..., R_{n-1}$

For this case the reliability of the sytem would be given by:

$R= \prod_{i=1}^n R_i$

R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6

And replacing we got:

$R = 0.95*0.95*0.5*0.79*0.6= 0.21389$

Step-by-step explanation:

We can assume that the system work in series

If we have in general n units the reliability of the system is the probability that unit 1 succeeds and unit 2 succeeds and all of the other units in the system succeed. fror n units must succeed for the system to succeed. The reliability of the system is then given by:

$R = P(R_1) P(R_2|R_1) P(R_3|R_2)*....*P(R_n |R_1,..., R_{n-1}$

For this case the reliability of the sytem would be given by:

$R= \prod_{i=1}^n R_i$

R1= 0.95, R2 =0.95, R3= 0.5, R4 = 0.79 , R5 = 0.6

And replacing we got:

$R = 0.95*0.95*0.5*0.79*0.6= 0.21389$

What is 162% of 400? Rounded to the nearest hundredth.

finlep [7]

Answer:

648

Step-by-step explanation:

Write 162% as 162 /100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

162 /100 of 400 = 162 /100 × 400

Therefore, the answer is 648

If you are using a calculator, simply enter 162÷100×400 which will give you 648 as the answer

Marta_Voda [28]

Answer:

$\sqrt{15.25}$

Step-by-step explanation:

Use distance formula

$\sqrt{((-6.25)-(-3.75))^{2} +(5-2)^2 } \\\\\sqrt{6.25 + 9} \\= \sqrt{15.25}$
