The 2017 population of California was 39536653 and of Arizona was 7016270. Compute and compare the rate of pedestrian fatalities
jasenka [17]

Answer:

The pedestrian fatality rate for California per 100,000 residents would be;

= (858/39,536,653) * 100,000

= 2.17 people per 100,000

In Arizona that figure is;

= (216/7,016,270) * 100,000

= 3.08 people per 100,000

<em>This shows that even though California has a higher number of pedestrian fatalities in absolute terms, when this figure is made relative to population, Arizona has more pedestrian fatalities. </em>

How do I write an equation in slope intercept form for a line that is parallel to the y-axis and has has an x-intercept of 3
Ket [755]

Answer:

x=3

Step-by-step explanation:

Keep in mind that the equation of the y-axis is simply x=0.  A line parallel to the y-axis that passes thru x = 3 has the equation x=3.  That's it.  

You cannot write this in slope intercept form because vertical lines don't have defined slopes.
