Answer:
Hence the correct option is option b) Yes, the upper level of one standard deviation is 72.
A score of 74 is not within one standard deviation of the mean.
Step-by-step explanation:
Here the given details are,
Mean = 68
SD = 4
Distribution is normal.
Z-score for x = 74 is given as below:
So, the score of 74 is 1.5 standard deviations from the mean.
Therefore the score is not lies between 64 and 72.
Yes, the upper level of one standard deviation is 72.

Step-by-step explanation:
Function 1 has rate of change of
(15.75 - 14.25)/(1 -(-1)) = 0.75. This was calculated using slope formula.
Function 2 has rate of change of 5/6, which is 0.833.
Answer:
r= -d x -t + w
Step-by-step explanation:
d= (w-r)/2 multiply by t to get dt=w-r, the subract w to get dt-w=-r. divide by negative 1 to get -dx-t+w=r (the x means to multiply)
Answer:
The cow's tail will grow 25 inches more intotal
The cows tail will be 28 inches long.
