Ok we need a common coefficient of either x or y:
12x+21y=3
12x+40y=60
We can subtract one from the other to get:
19y=57
Now divide by 19 to get:
y=3
Now if we sub this back in we see that:
3x+30=15
3x=-15
x=-5
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2
Answer:
If a Poisson process applies, we have the probability that k potholes are find in t miles as:
The probability that no more that one pothole will appear in a section of one mile is P=0.1353.
The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293.
Step-by-step explanation:
We have the rate of potholes:
