Answer:
C. 0.60
Step-by-step explanation:
We need to find out a couple things first:
- How many students are from Westville?
- How many students did not attend the game that are from Westville?
We need to find specifically Westville, because we don't want to accidentally pick someone from North Beach who attended.
So let's look:
- Total from Westville: 150
- Total who did not attend from Westville: 90
Now in order to find a probability, we need to divide the smaller number from the biggest number. Let's do that:
90/150 = 0.6
And for this question, we specifically have to round to two decimal places. In order to do this, we just write the extra 0 at the end:
0.6 = 0.60
Look at that, 0.60 is one of our answers! :D
Answer:
42 mi
Step-by-step explanation:
To find the perimeter, just add up all the side lengths.
13 + 14 + 15 = 42
<em>Note this is mi and not mi² since this is not area.</em>
Answer:
h(x) = 0.0045x – 0.4
Step-by-step explanation:
The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.
Flight A: f(x) = 0.003x - 1.2
Flight B: g(x) = 0.0015x + 0.8
Then the function
h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.
Therefore, the third option is the right option. (Answer)
