Let X be an exponential random variable with parameter 2. Find the CDF of X . Express your answer in terms of x using standard n
erastovalidia [21]

Answer:

F(x,\lambda) = 1-e^{2x}     for      x\geq0

and   F(x,\lambda) = 0    for   x

Step-by-step explanation:

Remember that the CDF of an exponental random variable is given by

F(x,\lambda) = \left \{ {{1-e^{\lambda x}  \ \  \ \ \  x\geq 0} \atop {0}  \ \ \ \ \ \  \ \ \ \ \ x

where   \lambda   is the parameter.  In this case    \lambda =  2  so, for this case

F(x,\lambda) = \left \{ {{1-e^{2x}  \ \  \ \ \  x\geq 0} \atop {0}  \ \ \ \ \ \  \ \ \ \ \ x

Hello hope your day is well i really need help with this expand question 4(a+5)-2(a-5)
BARSIC [14]

Answer:

2a + 30

Step-by-step explanation:

break it down so it is 4(a+5)

then work out -2(a-5)

so 4 x a then 4 x 5 which gives 4a + 20

then -2 x a then -2 x -5 which gives -2a + 10

then when you have 4a + 20 -2a + 10

do 4a - 2a which is 2a

do 20 + 10 which is 30

so the answer comes to 2a + 30

if anything doesnt seem right just comment and i will correct

hope this helps :)

Is y=3x+4 parallel or perpendicular
Sauron [17]

Answer: y=3x+4 is parallel to y=3x+7

Step-by-step explanation:

<h3> The complete exercise is: "Is y=3x+4 parallel, perpendicular or neither to y=3x+7?"</h3><h3 />

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

First, in order to solve this exercise it is important to remember that, by definition:

1. The slopes of parallel lines are equal.

2. The slopes of perpendicular lines are negative reciprocal.

In this case, you have the following line given in the exercise:

 y=3x+4

You can identify that "m" and "b" are:

m=3\\b=4

And the other line provided in the exercise is this one:

y=3x+7

So, you can identify that:

m=3\\b=7

As you can notice, the slopes of both lines are equal; therefore, you can conclude that those lines are parallel.
