Answer:

Option A

Step-by-step explanation:

Given function is,

f(x)=x^4-x^2-6

Hint: (-1=-3+2) and (-3)(2)=-6

f(x)=x^4-3x^2+2x^2-6

       =x^2(x^2-3)+2(x^2-3)

       =(x^2+2)(x^2-3)

f(x)=(x^2+2)(x^2-3) is the factored form of the given function.

Option A will be the correct option.

Data may be classified by one of the four levels of measurement. What is the name of the lowest level?
coldgirl [10]

Answer:

Nominal

Step-by-step explanation:

There are four levels of measurement of data listed below in increasing order:

Nominal

Ordinal

Interval

Ratio

The nominal level of measurement is the lowest level that deals with names, categories and labels. It is a qualitative expression of data e.g Colors of eyes, yes or no responses to a survey, and favorite breakfast cereal all deal with the nominal level of measurement.

Data at this level can't be ordered in a meaningful way, and it makes no sense to calculate things such as means and standard deviations.

A trapezoid has 9.2 inches base and 3.5 inches base, as well as 17 inches height. What is the area?
Tju [1.3M]
107.95in^{2}


The area of a trapezoid is as follows: 

A = \frac{a + b}{2} h

A and B are the lengths of the parallel lines of trapezoids. The parallel lines in this problem are 3.5 and 9.2. After adding those and dividing by 2, we multiply 17 to find the area of the trapezoid. (This is also shown in the attached picture)
