Find the slope of the line connecting (1990,435000) and (2005,482300):
482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is
given by y-435000 = 3153(30) = 94590, so that y = 529590.
Answer:
To find the average of a set of fractions,add all fractions, then divide the sum by the number of fractions as follows: Convert the integers and mixed numbers to improper fractions.
Step-by-step explanation:
Let
x-------> the number of persons in the family
f(x)------> the function represent the cost of living
we know that
The domain of the function would only include positive integers, because the number of persons can not be negative or a fraction
The range of the function would only include positive numbers, because the cost can not be negative
therefore
<u>the answer is the option B</u>
The domain would only include positive integers.
6 7/8. You must get a common denominater. I used 8, which multiplis 4 times 2. Then the top number is multiplied by 2 to get 2/8. Now add the tops and bottoms to get 7/8. Now add the whole numbers to get 6.
