Answer:
The two integers are 20 and 22.
Step-by-step explanation:
Let x be the first integer.
![(x+2)^{2}-x^{2} = 84\\x^{2} +4x+4-x^{2} = 84\\4x = 80\\x = 20](https://tex.z-dn.net/?f=%28x%2B2%29%5E%7B2%7D-x%5E%7B2%7D%20%3D%2084%5C%5Cx%5E%7B2%7D%20%2B4x%2B4-x%5E%7B2%7D%20%3D%2084%5C%5C4x%20%3D%2080%5C%5Cx%20%3D%2020)
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
