This graph displays a linear function. What is the rate of change?
2 answers:
Answer:
Rate of change = 5
Step-by-step explanation:
If a line passes through two points and
, then the rate of change of the line is
From the given graph it is clear that the line passes through the points (1,-1) and (2,4).
Using the above formula, the slope of the line is
Therefore, the rate of change of given line is 5.

Step-by-step explanation:
Given a normal distribution with ;
Mean = 36
Standard deviation = 4
According to the empirical rule :
68% of the distribution is within 1 standard deviation of the mean ;
That is ; mean ± 1(standard deviation)
68% of subjects :
36 ± 1(4) :
36 - 4 or 36 + 4
Between 32 and 40
2.)
95% of the distribution is within 2 standard deviations of the mean ;
That is ; mean ± 2(standard deviation)
95% of subjects :
36 ± 2(4) :
36 - 8 or 36 + 8
Between 28 and 44
3.)
99% is about 3 standard deviations of the mean :
That is ; mean ± 3(standard deviation)
99% of subjects :
36 ± 3(4) :
36 - 12 or 36 + 12
Between 24 and 48
