The 2017 population of California was 39,536,653 and of Arizona was 7,016,270. Compute and compare the rate of pedestrian fatalities per 100,000 residents.

Step-by-step explanation:

In 2017, California led the nation with 858 pedestrian fatalities. Arizona had only 216. The 2017 population of California was 39,536,653 and of Arizona was 7,016,270. Compute and compare the rate of pedestrian fatalities per 100,000 residents.

Solution

The pedestrian fatality rate for California per 100,000 residents

= pedestrian fatality in California / total population in California × 100,000

= (858 / 39,536,653) × 100,000

= 2.17 people per 100,000

The pedestrian fatality rate for Arizona per 100,000 residents

= pedestrian fatality in Arizona / total population in Arizona × 100,000

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

= 3.08 people per 100,000

This means that, though California may have a higher number of pedestrian fatalities compared to Arizona, the rate of pedestrian fatalities per 100,000 residents in California is lower compared to Arizona.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

536
