This question s incomplete, the complete question is;
The Watson family and the Thompson family each used their sprinklers last summer. The Watson family's sprinkler was used for 15 hours. The Thompson family's sprinkler was used for 30 hours.
There was a combined total output of 1050 of water. What was the water output rate for each sprinkler if the sum of the two rates was 55L per hour
Answer:
The Watson family sprinkler is 40 L/hr while Thompson family sprinkler is 15 L/hr
Step-by-step explanation:
Given the data in the question;
let water p rate for Watson family and the Thompson family sprinklers be represented by x and y respectively
so
x + y = 55 ----------------equ1
x = 55 - y ------------------qu2
also
15x + 30y = 1050
x + 2y = 70 --------------equ3
input equ2 into equ3
(55 - y) + 2y = 70
- y + 2y = 70 - 55
y = 15
input value of y into equ1
x + 15 = 55
x = 55 - 15
x = 40
Therefore, The Watson family sprinkler is 40 L/hr while Thompson family sprinkler is 15 L/hr

Answer:
A = {RRR, LLL, SSS}
Step-by-step explanation:
We are going to observe the direction of three consecutive vehicles.
The outcomes that we have to list are those of the event A where all three vehicles go in the same direction, this can be said as "the three vehicles turn right, the three vehicles turn left or the three vehicles go straight".
If the three vehicles turn right, the outcome would be: RRR.
If the three of them turn left, it would be: LLL.
If the three of them go straight, it would be: SSS.
It is obvious that these are the only 3 possible outcomes and therefore:
A = {RRR, LLL, SSS}
