Answer:
The given statement is,
(3 * 4) * 6 = 3(4 * 6)
To find (3 * 4) * 6
(3 * 4) * 6 = 12 * 6 = 72
To find 3(4 * 6)
3(4 * 6) = 3 * 24 = 72
Step-by-step explanation:
The result of these two expression is same.
Therefore we can conclude that,
Therefore the correct answer is,
The grouping of the factors is changed but the product is the same.

6a. By the convolution theorem,

6b. Similarly,

7. Take the Laplace transform of both sides, noting that the integral is the convolution of
and
.


where
. Then
, and

We have the partial fraction decomposition,

Then we can easily compute the inverse transform to solve for f(t) :


Answer:
The probability is 2/5
Step-by-step explanation:
Here, we want to calculate the probability that the first person will sit in a yellow roller coaster car
The number of cars to select from is 6 + 9 = 15 cars
The number of yellow cars is 6
So the probability that the first person selects a yellow roller coaster car to seat is 6/15 = 2/5
