Are polynomials determined to be a trinomial, binomial, etc. based on the number of operations or the terms?

1 answer:

5 0

Polynomials are determined to be a trinomial, binomial, etc by the amount of terms they have
For example
7x+3 is a binomial

A researcher examines typing speed before a typing class begins, halfway through the class, and after the class is over. 4. Iden

umka21 [38]

Answer:

Number of levels = 2

Type of design = Repeated measure

Dependent variable = Typing Speed

Step-by-step explanation:

The number of levels in an experiment simply refers to the number of experimental conditions in which participants are subjected to. In the scenario above, the number of levels is 2. Which are ; Halfway through the class and After the class is over.

The type of designed employed is REPEATED MEASURE, this is because the participants all took part in each experimental condition.

The dependent variable is TYPING SPEED, which is the variable which is measured with respect to the independent variable. Hence the observed value depends on period that is (halfway through the class or after the class is over).

Triangle XYZ is located at X (−2, 1), Y (−4, −3), and Z (0, −2). The triangle is then transformed using the rule (x−1, y+3) to f

Brrunno [24]

The given points are X (−2, 1), Y (−4, −3), and Z (0, −2)

By using the rule (x − 1, y + 3) the points then become:

X′ (− 2 − 1, 1 + 3), Y′ (− 4 − 1, − 3 + 3), and Z′ ( 0 −1, − 2 + 3)

X′ (− 3, 4), Y′ (− 5, 0), and Z′ (− 1, 1)

If the corresponding vertices of both triangles were connected with line segments then we should get exact congruent triangles with just x- and y-coordinates transformed or we can say that:

△XYZ=△X′Y′Z′

Answer: X′ (− 3, 4), Y′ (− 5, 0), and Z′ (− 1, 1)

You flip a coin and then roll a 6-sided number cube (a die).

expeople1 [14]

Answer:

a) No, it does not matter whether you roll the die or flip the coin first, as these two events are <u>independent</u> of each other, which means they do not affect each other.

b) Yes.
