Question 1194101: The median age of men at first marriage in 1970 was 23.2, and 29.2 in 2015.
a.) Use the two data points to find a linear function that fits the data. Let x =the number of years after 1970 and A=the median age at first marriage x years after 1970.
b.) Use the function to estimate the median age of men at first marriage in 2008 and in 2019.
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! (0, 23.2) and (45, 29.2)
point slope formula y-y1=m(x-x1), m slope and (x1, y1) point
slope is 6/45.
A-23.2=(6/45)(x-0)
A=(2/15)x+23.2
2008: x=38
(2/15)x=76/15 or 5.07, so age would be 28.27 or 28.3 years
2019 is 29.2-(2/15)=29.07 or 29.1 years
