Answer:
99.7%
Step-by-step explanation:
According to the Empirical Rule:
- 68% of data in a normal distribution are ±1σ from the mean μ
- 95% of data in a normal distribution are ±2σ from the mean μ
- 99.7% of data in a normal distribution are ±3σ from the mean μ
By calculating the z-score of each observed value, we can determine how many standard deviations these observed values are from the mean:


Clearly, we can see that 99.7% of males in the town have a systolic blood pressure between 99 and 141 by the Empirical Rule.
X=8
Explanation:
f(x)=x^2-16x+64+(x-8)^2
You see there is a double x- intercept by the 8. So the parabola is tangent to the x axis. So x=8 f(x)=0

Answer:
C=550+121m
Step-by-step explanation:
M equals the number of months while C equals the cost
Step-by-step explanation:
The line is
j --------K----------M---------N---------L
6. 4. 4. 4
JN = 14
KM = 4
KM = MN = LN =4
JK = 14 - (KM+MN)
JK = 14 - 8 = 6
JK = 6
MN = 4
LJ = 18
KN = 8
MJ = 10
NL = 4
