Answer: A/B *100,000.
Step-by-step explanation: Since crude death rate is the number of deaths of persons in a particular area divided by the total population of that area at a particular time multiplied by 100,000.
Mathematical expression :
(Total persons death in 2009/
Total population in 2009) * 100000
Answer:
amplitude = 5
Step-by-step explanation:
The amplitude is the average of the maximum value subtract the minimum value
maximum value = 6 and minimum value = - 4, hence
amplitude = 
= 
= 5
Make ur life easier by reducing the fraction first. divide both numbers by 100
now u have 7/2
now divide 7 by 2, u would get 3.5
Important fact: The slopes of perpendicular lines are negative reciprocals of one another. Thus, if the given line here has the slope 1/4, the slope of any line perpendicular to it will be -4 (the negative reciprocal of 1/4).
(0,2) is the y intercept of the new line.
Thus, the new line's equation is y = mx + b, or y = -4x + 2.
