Answer:
(a) [tex]\frac {276}{450}=\frac {y}{15240}[/tex]
(b) We cross multiply the probability by the total voters
(c) 9347
Step-by-step explanation:
(a)
Probability of getting a republican voter is
[tex]\frac {276}{450}=\frac {138}{225}=\frac {46}{75}[/tex]
[tex]\frac {276}{450}=\frac {138}{225}=\frac {46}{75}=\frac {y}{15240}[/tex]
These are found by dividing the first numerator and denominator by 2, then by 3
To make it complete, the situation is therefore defined as [tex]\frac {276}{450}=\frac {y}{15240}[/tex] where y is unknown value
(b)
Cross multiplication of the probability and number of voters gives the actual figure of y in the equation formed in part a of the question.
(c)
Since we have 15240 voters who plan to participate in election, we cross multiply to get the approximate number of republican voters which yields
[tex]\frac {46}{75}\times 15240=9347.2\approx 9347[/tex]
Answer:
[A] The ratios can be written LaTeX: \frac{\text{republican votes}}{\text{total votes}}republican votes total votes. So we can write the proportion LaTeX: \frac{276}{450} = \frac{x}{15240}276 450 = x 15240.
[B] Use the cross product to get 450x = 4,206,240. Divide to get x = 9347.2.
[C] The republican can estimate that he will get 9347 votes.
