It is given that the mean is 79.1 inches and standard deviation is 3.0 inches so it follows:
So the value from 75 to 81 is given by:
Use the table or a software to get the probability values and substitute to get the probability value as:
The probability is 0.6509.
Answer:
True
Step-by-step explanation:
For any function of the form the coefficient a produces a reflection of the function whenever
.
We can verify it in the following way.
Take, for example, the function:
Now let's make
Now let's in the following function:
We have:
We can see then that the function was reflected in the axis -y by placing a negative coefficient a.
You can see more examples in the attached images
Therefore we can conclude that the statement is true.
