The bar graph shows that life expectancy, the number of years newborns are expected to live, in a particular region has increased dramatically since ancient times. find the percent increase in average life expectancy of the region from the stone age to 2016.

There was an increase of 176.92 % of life expectancy

Step-by-step explanation:

To find this solution, we need to compare the life expectancy in the Stone age and in 2016

Stone age

26 years. (this represents 100%)

2016

72 years

We apply a rule of three

26 years 100%

72 years x

(72/26)*100% = 276.92 %

276.92 % - 100% = 176.92 %

There was an increase of 176.92 % of life expectancy

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
