Answer:
I'm not 100% but I think it could be x4 and then +5?
Step-by-step explanation:
Switch the x and y values and isolate y, then simplify.
x=6y+5
6y=x-5
y=1/6x-5/6
When you divide 36.89/8.6, you get should $4.29 for 1 gallon of gas.
Answer:
You need to find the average for your numbers
Step-by-step explanation:
Answer:
The parameters of this exponential distribution is = .
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;
where, = parameter of distribution.
Now, the mean of exponential distribution is = which is given to us as average value of 27 minutes that means .
So, X ~ Exp( ) .
Therefore, the parameter of this exponential distribution is .
