Answer:
0.0337 = 3.37% probability that a particular death is due to an automobile accident
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is the probability that a particular death is due to an automobile accident?
Total of 1008 deaths.
34 resulted from an automobile accident. So
0.0337 = 3.37% probability that a particular death is due to an automobile accident

Answer:
The translation did not effect the domain
The translation effected the range
Step-by-step explanation:
The given graph represents f(x) = IxI
The domain of f(x) is {x : x ∈ R}, where R is the set of real numbers
The range of f(x) is {y : y ≥ 0}
The graph of g(x) is attached down
g(x) = IxI + 4
The domain of g(x) is {x : x ∈ R}, where R is the set of real numbers
The range of g(x) is {y : y ≥ 4}
The graph of g(x) is the image of the graph of f(x) after translate it 4 units up
∵ The translation is vertically
∴ The domain of f(x) = the domain of g(x)
∵ The domain of f(x) is {x : x ∈ R}
∴ The domain of g(x) is {x : x ∈ R}
∴ The translation did not effect the domain
∵ g(x) = f(x) + 4
∵ The range of f(x) is {y : y ≥ 0}
- Add 4 to the value 0
∴ The range of g(x) is {y : y ≥ 0 + 4}
∴ The range of g(x) is {y : y ≥ 4}
∴ The range of g(x) not equal the range of f(x)
∴ The translation effected the range
Mila spent 4 hours at baby sitting and 6 hours at life guarding
<em><u>Solution:</u></em>
Given that, Mila is working two summer jobs, making $9 per hour babysitting and $17 per hour life guarding
Amount earned from babysitting = $ 9 per hour
Amount earned from life guarding = $ 17 per hour
Last week Mila earned a total of $138 and worked 2 more hours life guarding than hours babysitting
Let "b" represent the number of hours spent babysitting
Then, the number of hours spend at life guarding is b + 2
Also, total amount earned last week = $ 138
<em><u>Then, we can frame a equation as:</u></em>
Amount earned from babysitting x number of hours spent babysitting + Amount earned from life guarding x number of hours spend at life guarding = 138
<em><u>Then, number of hours spent at life guarding:</u></em>
b + 2 - 4 + 2 = 6 hours
Thus she spent 4 hours at baby sitting and 6 hours at life guarding
