Answer: c.
Step-by-step explanation:
As per given , we have
Total number of residents injured from roller-skating =1,800
Total number of deaths from roller-skating = 90
Formula for Mortality rate : 
Then, the proportional mortality ratio (%) due to roller-skating was
=
= 5%
Hence, the correct answer is c.
Answer:
the angle in upper and the lower corners have to be the same, so we can write an equation
5p-62 = 6p-88
(this picture is indeed complicated to read)
rearrange the equation
-62 = 1p-88
26 = p

Answer:
Step-by-step explanation:
Given is a Laplace transform of f(t) as

Let

Solving we get 

Solving B=0=D

Hence we have
f(t) = inverse Laplace of
![\frac{1}{7}[ \frac{s}{(s^2+9)}-\frac{s}{(s^2+16)}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D%5B%20%5Cfrac%7Bs%7D%7B%28s%5E2%2B9%29%7D-%5Cfrac%7Bs%7D%7B%28s%5E2%2B16%29%7D%5D)
