Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 and c = 2, thus
y = 3x + 2 → C
Answer:
The probability that a repair time exceeds 8 hours is 
The conditional probability that a repair takes at least 13 hours, given that it takes more than 9 hours is 
Step-by-step explanation:
A continuous random variable X is said to have an exponential distribution with parameter
shown as
, if its probability density function is given by

Let X denote the time require to repair a machine.
(a) The probability that a repair time exceeds 8 hours;

(b) The conditional probability that a repair takes at least 13 hours, given that it takes more than 9 hours;
We want to find
.
