ANSWER:
The average burnout time of a large number of bulbs has a sampling distribution that is close to Normal.
STEP-BY-STEP EXPLANATION:
The cental limit theorem states, that id the sample size is large (30 or more), then the sampling distribution of the sample means is approximately normal with mean ц and standar deviation б/
Thus the correct answer is the average burnout time of a large number of bulbs has a sampling distribution that is close to Normal.

We then have as parallel edges:
AC and GE
CG and AE
CD and GH
AB and EF
BD and HF
DH and BF
CD and EF
GH and AB
Answer:
8 pairs of parallel lines
Considering the definition of an equation and the way to solve it, the total cost of the shoes is 0.20×(x-15).
<h3>Definition of equation</h3>
An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.
<h3>Total cost in this case</h3>
Being "x" the price of the shoes, and knowing that:
- you apply a discount of $15 first → x -15
- you apply a discount of 20% through a second discount (
- (applied on the first discount already made) → 20%×(x-15) → 0.20×(x-15)
the equation in this case is:
<u><em>Total cost= 0.20×(x-15)</em></u>
Finally, the total cost of the shoes is 0.20×(x-15).
