Answer:
The second one:
x 2-2 3-3
y 5 5 7 7
Step-by-step explanation:
Each domain value or x can only have one range, y, so, with that said, the second one is the answer.
Answer:
Lori would have to save $5,760
Step-by-step explanation:
Since 320×6=1920, you would have to add to see witch number would be best to save up too. You would get $5,760 when you multiple by 3.If you multiple by 2,it wouldn't give you enough money.
Answer:
a) 0.2
b) 0.2
c) 0.5
Step-by-step explanation:
Let
be the event "the car stops at the signal.
In the attached figure you can see a tree describing all possible scenarios.
For the first question the red path describes stopping at the first light but not stopping at the second. We can determine the probability of this path happening by multiplying the probabilities on the branches of the tree, thus

For the second one the blue path describes the situation

For the las situation the sum of the two green path will give us the answer

B = 16
x^2 + 16x + 64 can be factored down to (x + 8)^2.
Answer:
The required function is:

Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get

Hence,
The required function is:
