Answer:
G
Step-by-step explanation:
Using the rule of exponents
= 
Consider the left side
=
, then
= n²
Since bases on both sides are equal, equate the exponents
x - y = 2 → G
A square has 4 right angels and 4 sides with equal angels ;)
There would be about 19 defective products delivered.
First, let's start with the number of defective games.
100000 x 0.0095 = 950
Now, the test will catch 98% of those defects. That means 2% of the defects will get through to the consumers.
0.02 x 950 = 19
If a is the number of events, then a = 1. Plugging in 1 for a in the equation

, you get

.
Total cost is $9.
First, since we must follow PEMDAS, we need to do the operation that is first, which is addition.
-3.9 + 6.01 ← Adding a negative means subtracting, then giving the sign of the bigger number.
So now we solved those and we got this answer: 2.11
Now, we need to subtract and re-write the expression.
2.11 - (-7.423) = 2.11 + 7.423= 9.533
Ok....so now we have our final answer, and we have the choices above.
The only answer that matches ours is the last one.
Final answer: 9.533
Hope I helped ^_^
