Answer:
Step-by-step explanation:
Answer:
The correct answer is A. 3/5
You need to form an equation:
P+2/3P+1/2P=234
P+4/6P+3/6P=234
P+7/6P=234
13/6P=234
P=234/(13/6)
P=108
Answer:
56% ≤ p ≤ 70%
Step-by-step explanation:
Given the following :
Predicted % of votes to win for candidate A= 63%
Margin of Error in prediction = ±7%
Which inequality represents the predicted possible percent of votes, x, for candidate A?
Let the interval = p
Hence,
|p - prediction| = margin of error
|p - 63%| = ±7%
Hence,
Upper boundary : p = +7% + 63% = 70%
Lower boundary : p = - 7% + 63% = 56%
Hence,
Lower boundary ≤ p ≤ upper boundary
56% ≤ p ≤ 70%
