Step-by-step explanation:
We can simplify this fraction down further by divide both numerator and denominator by 2:
10/2 = 5
12/2 = 6
5/6 will be equivalent to 10/12
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

Answer:
<em>The maximum number of kilowatt-hours is 235</em>
Step-by-step explanation:
<u>Inequalities</u>
Robert's monthly utility budget is represented by the inequality:
0.1116x + 23.77 < 50
Where x is the number of kilowatts of electricity used.
We are required to find the maximum number of kilowatts-hours used without going over the monthly budget. Solve the above inequality:
0.1116x + 23.77 < 50
Subtracting 23.77:
0.1116x < 50 - 23.77
0.1116x < 26.23
Dividing by 0.1116:
x < 26.23/0.1116
x < 235
The maximum number of kilowatt-hours is 235
