Is (3,-2) a solution to the system below? How do you know?
cricket20 [7]

Step-by-step explanation:

you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.

if yes, it was a solution, and if just only one is false, then it was not a solution.

(3, -2) in

y + 4x = 10

5x - y = 13

so,

-2 + 4×3 = 10

-2 + 12 = 10

10 = 10 true

5×3 - (-2) = 13

15 + 2 = 13

17 = 13 false

so, it was NOT a solution.

Suppose you have already been waiting for one hour for a taxi. what is the probability that one arrives within the next 10 minut
Alona [7]

The probability of one arrives within the next 10 minutes when he already been waiting for one jour for a taxi is,

 

P (X > 70 | X > 60) = P (X > 10) = 1 – P (X ≤ 10) = 1 – {1 – e ^ -((1 / 10) 10)} = e ^ -1

= 0.3679

 

The probability of one arrives within the next 10 minutes when he already been waiting for one hour for a taxi is 0.3679
