Answer:
-6
Step-by-step explanation:
5p - 14 = 8p + 4
Subtract 8p from both sides.
-3p - 14 = 4
Add 14 to both sides.
-3p = 18
Divide both sides by -3.
p = -6
Answer: -6
95% have a systolic blood pressure between 109 and 141
Empirical rule states that for a normal distribution, 68% are within one standard deviation from the mean, 95% are within two standard deviation from the mean and 99.7% are within three standard deviation from the mean.
Given that mean (μ) = 125, standard deviation (σ) = 8.
68% are within one standard deviation = μ ± σ = 125 ± 8 = (117, 133)
95% are within two standard deviation = μ ± 2σ = 125 ± 2*8 = (109, 141)
95% have a systolic blood pressure between 109 and 141
