Answer:
p is approximately equal to 1.125, -1.925
Step-by-step explanation:
We can solve this first by expanding, giving us a quadratic equation in the usual ax² + bx + c format, then solving that for p:
(4p - 4)(13p + 27) = 0
52p² + 108p - 52p - 108 = 0
52p² + 52p - 108 = 0
13p² + 13p - 27 = 0
13p² + 13p = 27
p² + p = 27 / 13
p² + p + 1/4 = 27/13 + 1/4
(p + 1/2)² = 108 / 52 + 13 / 52
(p + 1/2)² = 121 / 52
p + 1/2 = ± √(121 / 52)
p = -1/2 ± 11√(1/13) / 2
At that point we can simply plug those numbers into a calculator and solve it:
p ≈ 1.125, -1.925

Answer:
M has 41 CDs
Step-by-step explanation:
Joel = 2 x M
(Joel -7) / 3 = Black
Black = 25
Joel - 7 = 3 x Black = 3 X 25 = 75
Joel = 75 + 7 = 82
M = 82 / 2 = 41

Answer:
D. 68.00%
Step-by-step explanation:
Population mean time (μ) = 32 hours
Standard deviation (σ) = 2 hours
Assuming a normal distribution, for any given number of hours 'X', the z-score is determined by:
For X=30
For a z-score of -1, 'X' corresponds to the 15.87-th percentile of a normal distribution.
For X=34
For a z-score of 1, 'X' corresponds to the 84.13-th percentile of a normal distribution.
The percentage of the garages that take between 30 and 34 hours to erect is:
The percentage is roughly 68%.
