The box and whisker plot below represents students test scores of mr. ali’s history test.

c. mr. ali’s wanted more than half of the students to score 75 or greater on the test. explain how you know that more than half of the students did not score greater than 75.

I know that more than half of the students did not score more than 75 because the median (the middle number) is 68.

Step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
