Answer:

9x^2+4x+5

Step-by-step explanation:

f ( x ) = 5x^2 - 2x + 6

g ( x ) = 4x^2 + 6x - 1,

Add the functions together

f(x)+ g(x) = 5x^2 - 2x + 6 + 4x^2 + 6x - 1

Combine like terms

               =9x^2+4x+5

Determine whether the bolded numerical value is a parameter or a statistic. Explain your reasoning.The average annual salary of
sergey [27]

Answer:  F. Statistic​, because the data set of salaries of 50 employees is a sample.

Step-by-step explanation:

A parameter gives measure of a characteristic for the entire population where as a statistic gives measure of a characteristic for the subset of population (sample).

Given : The average annual salary of 50 of a company's 800 employees is $54,000.

It means the sample size = 50 and the sample mean salary= $54,000.

i.e $54,000 is giving the measure for mean salary for the sampled 50 employees.

It means $54,000 is a statistic .

Hence, the correct answer is option (F).

Answer:

A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.

A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.

There are many different methods in arriving to the final answer. However, errors cannot be perfectly avoided. One of these errors to mistakenly identify equations as linear. It is important that we know that the equations we are dealing with are of exact or correct  characteristics.

Also, if she had used substitution method, she might have mistakenly taken the value of one variable for the other.
