or linear model of the given information we need to write the equation of a line
taking the datas from year 1970 and 1980
since x be the year since 1970 so for 1970 x=0 and for 1980 x=10
now for 1970 population=8.3 and for 1980 it is 10.3
we need to write the equation using (0,8.3) and (10,10.3)
x=0 y=20.2
Using time as the input, find a quadratic model for the data set for the percentage of men age 65 or older below poverty level. (x is the years since 1970. Round all numerical values to three decimal places.)
p(x)=.022x^2-1.085x+20.070 % is the percentage of men in the U.S. of age 65 and older living below the poverty level x years after 1970, 0 ? x ? 30
b.Using time as the input, find a quadratic model for the data set for the percentage of men age 65 or older below poverty level. (x is the years since 1970. Round all numerical values to three decimal places.)
p(x)=.022x^2-1.085x+20.070 % is the percentage of men in the U.S. of age 65 and older living below the poverty level x years after 1970, 0 ? x ? 30
l(x) = m(x) � p(x) / 100
l(x)=(0.2x+8.3)*(.022x^2-1.085x+20.070)/100
for year 1990 x=1990-1970=20
l(x)=12.3*7.17/100=0.881
for year 2000
x=30
substituting x to the derived equation below, we have m = 0.2*30 + 8.3, the answer is 14.3 Million
