Answer:
190
Step-by-step explanation:
57.5 x 2=115 so that is the arc for CE
then you add that to 55 to get 170
a circle is 360 so then you subtract 360 for 170

Answer:
Step-by-step explanation:
√(x)
Shifted 3 units down:
√(x) - 3
Shifted 2 units to the right:
√(x-2) - 3
It's the last one.
Answer:
5.0 ft-lbf
Step-by-step explanation:
The force is

This force is not a constant force. For a non-constant force, the work done, <em>W</em>, is

with
and
the initial and final displacements respectively.
From the question,
and
.
Then

Evaluating the indefinite integral,

From the rules of integration,


Returning the limits,

Answer:
The sampling distribution of X, for a sample of size 16, will be approximately normal with mean 2 mm and standard deviation 0.01 mm.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For the population:
Mean 2 mm, standard deviation 0.04 mm
Describe the sampling distribution of X (for a sample of size 16).
Sample of size 16 means that 
By the Central Limit Theorem, approximately normal with mean 2 and standard deviation
