An epidemiologic survey of roller-skating accidents in funville, ca a city with a population of 100,000, produced the following: 1. number of skaters in funville during any given month: 12,000 2. roller-skating accidents in funville: 600 3. total number of residents injured from roller-skating: 1,800 4. total number of deaths from roller-skating: 90 5. total number of deaths from all causes: 900 what is the cause-specific mortality rate (from roller skating) in funville?

The mortality rate due to the roller skating is 10%

Step-by-step explanation:

Given:

Population of the city = 100,000

Number of skaters in Funville during any given month = 12,000

Roller-skating accidents in Funville = 600

Total number of residents injured from roller-skating = 1,800

number of deaths from roller-skating = 90

Total number of deaths from all causes = 900

Now,

The cause-specific mortality rate (from roller skating) in Funville

=

=

= 10%

Hence,

The mortality rate due to the roller skating is 10%

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
