Answer:
Step-by-step explanation:
Option 1:
Using the following rule:
Put in our expression,
a = 2
n = 3
m = 2
Option 2:
Using the following rule:
Since our expression is the same as multiplying 2³ with itself, we can write it as a multiplication.
If we compare this with 
, we can see that
a = 2
n = 3
m = 3 (in this case, n and m are equal)

Answers below
Step-by-step explanation:
1. Order pair method
[(x2-x1) , (y2-y1)] = b-a = [(7--9) , (3-9)] = (16,-6)
2. Magnitude

v = |17.088|
Question options :
a. They should be between 64 and 76 inches tall.
b. They should be close to the height that is 95% of the mean. That is, 66.5 inches, plus or minus 2 standard deviations.
c. They should be at or below the 95th percentile, which is 74.92 inches.
d. None of the above.
Answer: a. They should be between 64 and 76 inches tall.
Step-by-step explanation:
Given the following :
Assume men's height follow a normal curve ; and :
Mean height = 70 inches
Standard deviation= 3 inches
According to the empirical rule ;
Assuming a normal distribution with x being random variables ;
About 68% of x-values lie between -1 to 1 standard deviation of the mean. With about 95% of the x values lying between - 2 and +2 standard deviation of mean. With 99.7% falling between - 3 to 3 standard deviations from the mean.
Using the empirical rule :
95% will fall between + or - 2 standard deviation of the mean.
Lower limit = - 2(3) = - 6
Upper limit = 2(3) = 6
(-6+mean) and (+6+ mean)
(-6 + 70) and (6+70)
64 and 76
