ANSWER
The correct option is,
EXPLANATION
We were given that the solutions of the quadratic equation are
and
This tells us that,
and
are factors of the quadratic equation.
This implies that the quadratic equation is of the form,
We were also told that
is a non zero constant.
This means that we can use k to multiply the whole equation and the solution will not be affected.
Our equation now becomes,
Hence the correct answer is A.
Answer:
Step-by-step explanation:
We have been given that the The annual salaries of all employees at a financial company are normally distributed with a mean of $34,000 and a standard deviation of $4,000.
To solve our given problem we will use z-score formula.
where,
,
,
,
Upon substituting our given values in z-score formula we will get,
Therefore, the z-score of a company employee who makes an annual salary of $54,000 is 5.
