Let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes. If the random var
jeka57 [31]

Answer:

The parameters of this exponential distribution is \lambda = \frac{1}{27} .

Step-by-step explanation:

We are given that the random variable X is known to be exponentially distributed and let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes.

<u><em>So, X = time it takes for a person to choose a birthday gift</em></u>

The probability distribution function of exponential distribution is given by;

 f(x) = \lambda e^{-\lambda x}  , x >0      where, \lambda = parameter of distribution.

Now, the mean of exponential distribution is = \frac{1}{\lambda}  which is given to us as average value of 27 minutes that means  \lambda = \frac{1}{27} .

So, X ~ Exp( \lambda = \frac{1}{27} ) .

Therefore, the parameter of this exponential distribution is \lambda .

Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2). (answer in slope-intercept form)
Ymorist [56]
Perpendicular means that you will flip and change sign in this case we have -3 when we flip it and change sign we will get 1/3
So,

First we have to find b:

2=1/3(3)+b
2=1+b
1=b

Second you just write your equation:

Y= 1/3x + 1

Hope it help sweetheart!!
