Question

The Table below gives you The population of Texas since 1970. Find the average rate if change from 1970 to 1090

Answer 1

Average rate of change = 0.29 million per year

Explanation:

Average rate of change in the population from year 1970 to year 1900 is given by the formula,

Average rate of change =
`\frac{\text{Population in year 1990-Population in year 1970}}{1990-1970}`

=
`(17-11.2)/(1990-1970)`

=
`(5.8)/(20)`

= 0.29 million per year

Therefore, average rate of change in the population from 1970 to 1990 will be 0.29 million per year.
