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%

Answer:
4a^3b^2c^4
Step-by-step explanation:
(a^2b^2c)(4ac^3)=4a^3b^2c^4
Answer:
c = 15
Step-by-step explanation:
The angles are4 a linear pair and are supplementary, so the sum of their measures is 180 deg.
7c - 7 + 6c - 8 = 180
13c - 15 = 180
13c = 195
c = 15
