Answer:

Step-by-step explanation:

First, you need to know the formula for a triangle: a=b*h*1/2

Now, let's plug in the values. It should look like this, 14=b*7*1/2

We know that whatever is multiplied by 7 must be divided by 2 (or *1/2) to get 14.

So, knowing this we can multiply 14*2=28 becuase 28/2=14. Now we do 28/7=4.

(14=4*7*1/2)

Hope this helps

The length I’m guessing is either 2 because 7 x 2 = 14 or it’s 7 because 7 + 7 = 14. But I would go with 2.

Answer:

a) For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

$X \sim Unif(a=0,b=8)$

Where a and b represent the limits of the distribution.

b) $f(x) = \frac{1}{8}= 0.125, a\leq x \leq b$

And the height for this case would be 0.125

Step-by-step explanation:

Part a

For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

$X \sim Unif(a=0,b=8)$

Where a and b represent the limits of the distribution.

Part b

For this case the density function would be given by:

$f(x) = \frac{1}{8}= 0.125, a\leq x \leq b$

And the height for this case would be 0.125

And $f(x)= 0$ for other case.
