Answer:
38.46%
Step-by-step explanation:
There are no names or marking that can make the calculator look different, so the order is not important. Then we should use a combination to solve this problem.
There are 40 calculators in one shipment, 37 of them good items and 3 of them are defect items. We need to choose 19 good calculators and 1 defect calculator. The number of ways to do that will be:
* 
= 37!
= 53017895700
The number of possible ways to choose 20 calculators out of 40 calculators will be:
= 
=137846528820
The chance will be: 53017895700/ 137846528820 = 0.3846= 38.46%
66 = 4 + 8v - 2 <== ur equation
66 = 2 + 8v
66 - 2 = 8v
64 = 8v
64/8 = v
8 = v <=== there are 8 bulbs in each value pack
The correct simplification of 8x2(5x 2x2 − 3) is 
<h3>What do you mean by simplification?</h3>
- Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
- Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
- Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.
The correct simplification of 8x2(5x 2x2 − 3).
Rearranging the above expression in descending order of power, we get:
The correct simplification of 8x2(5x 2x2 − 3) is

To answer this question, you can use the values of the unit circle to figure out the angle measurement. Since the cosine is the x value of the circle, we can see that at 45°<span>, the x value is √2/2.
So the missing angle should be 45°</span>
