Answer: The answer is (B). K'(-6,-4) and L(-3,-3).
Step-by-step explanation: In the figure, the parallelogram JKLM is drawn on a co-ordinate plane. Here, the co-ordinates of points K and L are (-4,6) and (-3,3) respectively.
Now, when we rotate the parallelogram about the origin through 270° , then we have to make a jump of three consecutive quadrants,.ie., presently we are in the fourth quadrant, so we will the resulting co-ordinates in the third quadrant and so both x and y co-ordinates of the new points will be negative. Also, the x-co-ordinate and y-co-ordinates of both the points K and L will get reversed. Please see the attached figure.
Thus, the new co-ordinates of K and L are K'(-6,-4) and L(-3,-3).
Answer:
The distribution is
Solution:
As per the question:
Total no. of riders = n
Now, suppose the is the time between the departure of the rider i - 1 and i from the cable car.
where
= independent exponential random variable whose rate is
The general form is given by:
(a) Now, the time distribution of the last rider is given as the sum total of the time of each rider:
Now, the sum of the exponential random variable with with rate
is given by:
