Question 111204
Remember, when setting up a proportion, be sure that the two sides are consistent with respect to the labels.
In your problem, you are dealing with "pedestrian deaths" and "population"
You are given:
1.83 deaths per (over) 100,000 residents (population) and the can be written as a ratio:
{{{1.83/100000}}} Deaths over population.
You need to find how many (x) residents (population) are in Texas if the proportional deaths were 419, so you can write this as a ratio:
{{{419/x}}} Deaths over population.
Set these two ratios equal to each other to get a proportion that you can solve.
{{{1.83/100000 = 419/x}}} Now solve this for x to find the answer to your problem. Invert both sides.
{{{100000/1.83 = x/419}}} Multiply both sides by 419.
{{{(419)(100000)/1.83 = x}}}
{{{x = 22896174.8634}}} Round to nearest whole person.
x = 22,896,175
