Step-by-step solution

Part a

The number of votes acquired by Dalaba is 2213\boxed{\frac{22}{13}}.

Part b· 1 step

Step 1: Calculate the exact number of votes for each contestant.

From part (a), we found x=2213x = \frac{22}{13}.

  • Agbeke: 14x=14×2213=3081314x = 14 \times \frac{22}{13} = \frac{308}{13} votes
  • Katume: 11x=11×2213=2421311x = 11 \times \frac{22}{13} = \frac{242}{13} votes
  • Dalaba: x=2213x = \frac{22}{13} votes
  • Dramani: 52 votes
  • Quainoo: 24 votes The total number of votes is 120.
  1. Calculate the angle for each contestant's sector in the pie chart.

    The total angle in a circle is 360∘360^\circ. The angle for each contestant is given by (votestotal votes)×360∘\left(\frac{\text{votes}}{\text{total votes}}\right) \times 360^\circ.

    • Agbeke: (308/13120)×360∘=30813×120×360∘=30813×3∘=92413∘≈71.08∘\left(\frac{308/13}{120}\right) \times 360^\circ = \frac{308}{13 \times 120} \times 360^\circ = \frac{308}{13} \times 3^\circ = \frac{924}{13}^\circ \approx 71.08^\circ
    • Katume: (242/13120)×360∘=24213×120×360∘=24213×3∘=72613∘≈55.85∘\left(\frac{242/13}{120}\right) \times 360^\circ = \frac{242}{13 \times 120} \times 360^\circ = \frac{242}{13} \times 3^\circ = \frac{726}{13}^\circ \approx 55.85^\circ
    • Dalaba: (22/13120)×360∘=2213×120×360∘=2213×3∘=6613∘≈5.08∘\left(\frac{22/13}{120}\right) \times 360^\circ = \frac{22}{13 \times 120} \times 360^\circ = \frac{22}{13} \times 3^\circ = \frac{66}{13}^\circ \approx 5.08^\circ
    • Dramani: (52120)×360∘=52×3∘=156∘\left(\frac{52}{120}\right) \times 360^\circ = 52 \times 3^\circ = 156^\circ
    • Quainoo: (24120)×360∘=24×3∘=72∘\left(\frac{24}{120}\right) \times 360^\circ = 24 \times 3^\circ = 72^\circ

    To draw the pie chart, you would divide a circle into sectors with these angles.

Step 1: Identify the winner of the contest.

Compare the number of votes for each contestant:

  • Agbeke: 30813≈23.69\frac{308}{13} \approx 23.69 votes
  • Katume: 24213≈18.62\frac{242}{13} \approx 18.62 votes
  • Dalaba: 2213≈1.69\frac{22}{13} \approx 1.69 votes
  • Dramani: 52 votes
  • Quainoo: 24 votes The contestant with the highest number of votes is Dramani, with 52 votes.
  1. Calculate the percentage of total votes obtained by the winner.

    Percentage=Winner’s votesTotal votes×100%\text{Percentage} = \frac{\text{Winner's votes}}{\text{Total votes}} \times 100\% Percentage=52120×100%\text{Percentage} = \frac{52}{120} \times 100\% Percentage=5200120%\text{Percentage} = \frac{5200}{120}\% Percentage=52012%\text{Percentage} = \frac{520}{12}\% Percentage=1303%\text{Percentage} = \frac{130}{3}\% Percentage=4313%\text{Percentage} = 43\frac{1}{3}\%

    The percentage of total votes the winner obtained is 4313%\boxed{43\frac{1}{3}\%}.
