Answer:
HERE IS YOUR ANSWER IN PICTURE.
Answer:
Fourth option
Step-by-step explanation:
The answer is the fourth option "difference of squares method." It's not the first option because the substitution method is when you pick one of the equation in a system of equations, solve it for a variable and then plug the variable into the other equation to help solve. It's not the second option because the graphing method is used to solve a system of equations by graphing the equations on the same coordinate plane, it's not the third option because the addition method is also known as the elimination method which is the third method to solving a system of equations. Therefore your answer is the fourth option.

Assuming scores are normally distributed, a score of 82% on Ms. Smith's test corresponds to the 
-th percentile, i.e.
where 
is a random variable denoting scores on Ms. Smith's test.
Transform to 
, which follows the standard normal distribution:
which means Amy scored at the 99.98th percentile.
This makes it so that Karina needs to score 
on Mr. Adams' test so that
Their test scores have the same 
score computed above, so
so Karina needs to get a test score of at least 83.5%.
It is true if two vectors point in opposite directions. This means their cross product must be zero.
<h3>What is cross product?</h3>
Cross product is a vector product of two vectors in the three dimensional vector space.
In the case when the two vectors point in opposite directions so there cross product should be zero.
Impact on two points:
In the case when the two vectors point in opposite directions so there cross product should be zero.
Like
A*B = [A][B] sin
Here theta is be the angle that lies between them
So,
A*B = [A][B] sin 180
So, A*B = 0
hence, the given statement is true.
