Answer:

9 dollars

Step-by-step explanation:

Solve with a system of equations

Let adult tickets be a and student tickets be s

1. 8a + 13s = 176

2. 4a + 4s = 68

3. s = 17 - a

Equation 2 is friendlier, so let's divide all the numbers by 4.

a + s = 17

Equation is s = 17 - a

Substitute s in equation 1

8a + 13(17-a) = 176

8a + 221 - 13a = 176

221 - 5a = 176

5a = 45

a = 9

The price of an adult ticket is 9 dollars

Hope this helps :)

Solve x^2-11x=0, for x

ser-zykov [4K]

Start by factoring an x term out of the equation:

x(x-11)=0

Now, you can set each term equal to zero and solve for x:

x=0

x-11=0

x=11

x={0, 11}

Hope this helps!!

explain how the position of the decimal point changes in a quote as you divide by increasing powers of 10

Marianna [84]

If you have 20/10, that equals 2. Then if you move the decimal place over 1 place then you have 2. If you divide 2 again by 10, then move the decimal place over in another place, it is equaling 0.2.

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:

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