Alex needs to catch a train. The train arrives randomly some time between $1:00$ and $2:00$, waits for $10$ minutes, and then le

creativ13 [48]

The probability that the train will be there when Alex arrives is 5/18

If Alex arrives at any time after 1.20pm the chances that train will be there is 1/3.

However if alex arrives at 1.00pm exactly there is no chance the train will be arrive there.

The probability that the train will be there increase linearly to 1/3 as alex's arrival time moves from 1.00pm to 1.20pm.

By arranging the probabilities over the first 20 minutes to get a 1/6 chance the train will be there if alex arrives between 1.00pm to 1.20pm

we get the final answer by

=1/3( 1/6 + 1/3 + 1/3)

=5/18

So, the probability that the train will be there when Alex arrives is 5/18

Answer:

19.209 miles from each other.

Step-by-step explanation:

${a}^{2} + {b}^{2} = {c}^{2}$

Using this we get:

${15}^{2} + {12}^{2} = {x}^{2}$

$225 + 144 = 369 = {x}^{2}$

$\sqrt{369 } = 19.209$

Plot the zeros of this function:<br><br> f(x) = (x – 1)(x – 7).

vredina [299]

Answer:

$\boxed{\mathrm{view \: attachment}}$

Step-by-step explanation:

The zeros of a function is where the function crosses the x-axis. The x-intercepts are the zeros of a function.

$f(x) = (x - 1)(x - 7)$

Let output equal to 0.

$0 = (x - 1)(x - 7)$

Set factors equal to 0.

$x-1=0\\x=1$

$x-7=0\\x=7$

The zeros of the function are $x=1$ and $x=7$ .
