Answer:
The probability that the difference between the sample mean
and the true population mean
is : ![P[|\bar{x}-\mu|\leq0.7]=0.9876](https://tex.z-dn.net/?f=P%5B%7C%5Cbar%7Bx%7D-%5Cmu%7C%5Cleq0.7%5D%3D0.9876)
Step-by-step explanation:
Given :
Population standard deviation
.
Sample size 
The sample mean standard deviation
To find :
The probability that the difference between the sample mean
and the true population mean 

Now, the probability that the difference between the sample mean
and the true population mean
is :
,
is large 



Therefore, the probability ![P[|\bar{x}-\mu|\leq0.7]=0.9876](https://tex.z-dn.net/?f=P%5B%7C%5Cbar%7Bx%7D-%5Cmu%7C%5Cleq0.7%5D%3D0.9876)
Answer:
A and B
Step-by-step explanation:
Not C because
-5.75 < -5.45
In D, all are less than -5.45
Answer:
Answer should be 5
Step-by-step explanation:
Answer: OPTION D.
Step-by-step explanation:
The rate of change of a linear function is also known as "Slope".
The slope can be calculated with the following formula:

Choose two points on the function "R" graphed:

You can say that:

Substituting values into the formula, you get:

Choose two point from the table that models the function "S":

You can say that:

Substituting values into the formula, you get:

Therefore, you can conclude that the function "S" has a greater rate of change than Function "R".
Formula for area of a circle: A= C^2/ 4 π
A= 64^2/ 4 π
A= 4,096/ 4 π
A=3,216.99087728
A≈3,216
The area of the clock is about 3,216 inches
