Answer:
"=RAND()*(40) + 20"
Step-by-step explanation:
When we say that a random variable X follows an uniform distribution where a is the lower limit and the upper limit we are saying that each value on the interval (a,b) have the same probability of occur, and the density function is given by:
And for any other case.
For this special case we know that the random variable T="Waiting times at a toll booth" follows this distibution:
And we can use the excel to create random values on this range. So then the code to do this is given by:
"=RAND()*(b-a) + a"
"=RAND()*(60-20) + 20"
"=RAND()*(40) + 20"

Answer:
B: -2x² - 6x² - 6x + 3x + 3 + 2
Step-by-step explanation:
From the image attached, the given polynomial is;
3 - 6x - 2x² + 3x - 6x² + 2
For like terms to be next to each other, we have to rearrange it as follows;
-2x² - 6x² - 6x + 3x + 3 + 2
Like terms are x² and x, thus they are now arranged next to each other.
The only option that corresponds to our answer is option B
