What is the slope of the trend line, and what is it's meaning in practical terms? During which year was the life expectancy clearly higher than would have been expected from the linear trend? If the linear trend established by these data persisted through 2020, what would the life expectancy be for a child born in 2020? (round your answer one decimal place) If the linear trend established by these data persisted through 2300, what would be the life expectancy of a child born in 2300? (round your answer one decimal place) Does this make sense?

(-5,-28)

i graphed to on desmos.

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w

y=20x

: )

hope this
