Answer:
f(x) = 5x - 30
Yes it is a function
Step-by-step explanation:
Because when you input 0 you get -30 we know it starts at 0 or (0,-30). This gives us b in the equation y = mx + b.
We know that for every 4 cars washed it increases by 20. So 20/4 is 5. This tells us m = 5.
Plug it all in and you get y = 5x - 30 or f(x) = 5x - 30
Answer:
Step-by-step explanation:
<h2>This is an independent event probability problem , that is the first event does not affect the occurrence of the second event.</h2>The sample space of the first die is S1= {1,2,3,4,5,6}
The sample space of the second die is S2= {1,2,3,4,5,6}
1. the probability that the first number cube shows a Four pr (4)=
2. the probability that the second number cube shows an odd number=
odd numbers in the sample space are 1,3,5= 3
pr(odd)
For the two event to happen the probability is =
