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:

Where a and b represent the limits of the distribution.
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:

Where a and b represent the limits of the distribution.
Part b
For this case the density function would be given by:

And the height for this case would be 0.125
And
for other case.
The cumulative distribution function would be given by:



Matt's volume would be 90 cm. cubed
Mindy's volume would be 90 in. cubed
All I know is that you should multiply than add all of the products
Step-by-step explanation:
1kg of grapes = $1.50
=> 3.5kg of grapes = $1.50 * 3.5 = $5.25
1kg of carrots = $1.00
=> 2.25kg of carrots = $1.00 * 2.25 = $2.25
Total cost = $5.25 + $2.25 = $7.50.
Answer:
3
Step-by-step explanation:
Firstly, do the numbers inside the absolute value bars.
-6-(-3)
The two negatives that are together turn to a addition sign.
-6+3
You can just subtract 6 and 3 which is 3 and add the - to it.
|-3|
The -3 turns to a 3 since the absolute value bars make all numbers positive within the bars.
Hope this helped.
