Answer:

120

Step-by-step explanation:

Each new term is twice the previous term, so this is a geometric sequence. The applicable formula is

a(n) = a(1)*4*(n - 1)

and so a(9) = 4*4(9 - 1) = 120

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

ruslelena [56]

Answer:

Average rate of change = 0.29 million per year

Step-by-step explanation:

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

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

= $\frac{17-11.2}{1990-1970}$

= $\frac{5.8}{20}$

= 0.29 million per year

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