Solution: We are given:


Now let's find the estimated value of standard deviation using the range rule of thumb. According to range rule of thumb, the estimate of standard deviation is:

Therefore the estimated standard deviation is 0.690
is this an acceptable approximation?
Answer: c. Yes, because the error of the range rule of thumb's approximation is less than 15%.
Explanation:
The difference between estimated standard deviation and actual standard deviation is:
0.807 - 0.690 = 0.117
Now let's find the percentage of error
.
Therefore, the error of the range rule of thumb's approximation is less than 15%.
Answer:
22.5
Step-by-step explanation:
the formula is A=a+b
2h
Answer:
U' = (0,2)
V' = (0,5)
W' = (-5,5)
Step-by-step explanation:
To get these, you can subtract 2 from the x-value because they are moving 2 units to the left and add 2 to the y-value because they are moving 2 units up.
