The correct answer is C) Segment BD = 20.
Answer:
Step-by-step explanation:
Let X be the SRS scores of students.
Given that X is normal with standard deviation about 6.5.
Mean difference =
is desired
i.e. Z score should be 
Std error = std deviation of sample = 0.447
b) 
So std error must be 0.997 and sample size must be atleast 193 to get the difference of x bar and mu to lie within 1.3 points in either direction
Answer:
graph of function f of x equals 30 multiplied by 0.88 to the power of x
Step-by-step explanation:
The deodorant is begun to evaporate in other words, it is losing mass so the rate of 12% is a decay rate. In the exponential decay, the graph of the function goes according to the formula:

Where
is the initial amount (
),
is the rate of decay (
) and
the times intervals, in this case, measured in days. Substituting the values in the formula:

Which corresponds with the "graph of function f of x equals 30 multiplied by 0.88 to the power of x".
