The approximate increase in the number of software developers from 2016 to 2026
Answer to Problem 1IR
Explanation of Solution
Given information:
Pictograph showing the six occupations with the largest estimated numerical increase in employment in the United States between 2016 and 2026
Concept Used:
Pictograph is a graph in which pictures are used they contains a key that explains the meaning of the symbol used. It’s advantage is that comparisons can easily be made.
Calculation:
In order determine the approximate increase in the number of software developers from 2016 to 2026, we have to read the given pictograph and find the number of symbols software developers correspond to.
As, the given pictograph shows that the software developers corresponds to
Thus, the approximate increase in the number of software developers from 2016 to 2026 is
Thus, there is increment of approximate

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
