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:
x=12/5

Answer:
19/72 or 0.26388....
Step-by-step explanation:
Simplify the following:
((3/4 + 5/6)/2)/3
((3/4 + 5/6)/2)/3 = (3/4 + 5/6)/(2×3):
(3/4 + 5/6)/(2×3)
Put 3/4 + 5/6 over the common denominator 12. 3/4 + 5/6 = (3×3)/12 + (2×5)/12:
((3×3)/12 + (2×5)/12)/(2×3)
3×3 = 9:
(9/12 + (2×5)/12)/(2×3)
2×5 = 10:
(9/12 + 10/12)/(2×3)
9/12 + 10/12 = (9 + 10)/12:
((9 + 10)/12)/(2×3)
9 + 10 = 19:
(19/12)/(2×3)
(19/12)/(2×3) = 19/(2×3×12):
19/(2×3×12)
2×3 = 6:
19/(6×12)
6×12 = 72:
Answer: 19/72 or 0.26388....
There was a overall Decrease. (175 students down to 168) The overall percent of change would be 4%.
Imagine that you have - 1/4 and - 3/4, so - 0.25 and - 0.75. Look that - 0.25 is closer to 0 so
- 1/4 is bigger than - 3/4. In your case, - 25/40 is bigger than - 28/40 because its closer to 0.
