storchak [24]

Answer:

Step-by-step explanation:

Create a two-way table with the given information:

$\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & & 59 \\\cline{1-4} \sf Women & & & \\\cline{1-4} \sf Total & 84 & & 110 \\\cline{1-4} \end{array}$

Fill in the blanks in the table using <u>mathematical operations</u>:

⇒ Men unemployed = 59 - 40 = 19

⇒ Women employed = 84 - 40 = 44

⇒ Total women = 110 - 59 = 51

⇒ Total unemployed = 110 - 84 = 26

⇒ Women unemployed = 51 - 44 = 7

$\begin{array}{| c | c | c | c |}\cline{1-4} & \sf Employed & \sf Unemployed & \sf Total\\\cline{1-4} \sf Men & 40 & 19 & 59 \\\cline{1-4} \sf Women &44 & 7& 51 \\\cline{1-4} \sf Total & 84 &26 & 110 \\\cline{1-4} \end{array}$

Reading from the table, 7 women responded that they were unemployed.
