Question
Chapter 7, Problem 1IR
To determine
The increase in the number of software developers from the year 2016 to the year 2026.
Expert Solution & Answer
Answer to Problem 1IR
The increase in the number of software developers from 2016 to 2026 is approximately 260,000 workers.
Explanation of Solution
From the pictograph of “Jobs with Projected Highest Numerical Increase: 2016–2026”, it is observed that the number of symbols corresponding to software developers is 6.5.
Note that each symbol represents 40,000 workers.
Then, the increase in the number of software developers from 2016 to 2026 is
That is, 260,000 workers are software developers.
Thus, the increase in the number of software developers from 2016 to 2026 is approximately 260,000 workers.

Who has stronger evidence against the null hypothesis: Bob or Teresa?arrow_forwardf(x) = = x - 3 x²-9 f(x) = {x + 1 x > 3 4 x < 3 -10 5 10 5 5. 10 5- 07. 10 -10 -5 0 10 5 -101 :: The function has a “step" or "jump" discontinuity at x = 3 where f(3) = 7. :: The function has a value of f (3), a limit as x approaches 3, but is not continuous at x = 3. :: The function has a limit as x approaches 3, but the function is not defined and is not continuous at x = 3. :: The function has a removable discontinuity at x=3 and an infinite discontinuity at x= -3.arrow_forward
