Which ones? can someone help me(?)

Mathematics
1 answer:
drek231 [11]4 years ago
3 0

Answer:


Step-by-step explanation:

First, what's a polynomial?  It's an algebraic expression whose only independent variable is x, and in which all the x powers are either zero or positive and are integers:  x^3, x^2, x^1, x^0 (for example).

Looking at possible answer choice A, we immediately reject this because that power of x is in the denominator, representing 2x^(-3).  This negative power of x is not allowed.  Reject A.

In B, we have the powers x^2, x^1 and x^0.  Great.  This is a polynomial.

In C, we have x^2 + 1 in the denominator of the final fraction.  Reject this because of the final term.

In D, we have x^2 + 2x + √

A spinner is broken into section labeled 1 to 38. What is the probability that.On your next spin, that you will spin a 1?
VashaNatasha [74]

Answer:

1/38

Step-by-step explanation:

Given :

Probability = required outcome / Total possible outcomes

Total possible outcomes = total Numbe rod sections = 38

Required outcome = number of 1's on the entire section = 1

Hence, the probability of spinning a one equals :

P(spinning a 1) = 1 / 38

Which of the following BEST defines an output? please help me, I've been stuck on this one for a while!​
NeTakaya

A statement which best defines an output is: B. an output is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.

<h3>What is a function?</h3>

A function can be defined as a mathematical expression that defines and represents the relationship between two or more variable, which is typically modelled as input (x-values) and output (y-values).

<h3>The types of function.</h3>

In Mathematics, there are different types of functions and these include the following;

  • Periodic function
  • Inverse function
  • Modulus function
  • Signum function
  • Piece-wise defined function

In this context, we can infer and logically deduce that a statement which best defines an output is that it's the result of a relation or the function rule, which usually are the y-values in a set of ordered pairs, on a table or a graph.

Complete Question:

Which of the following best defines an output?

A. An output is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.

B. An output is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.

C. An output is a special type of relation for which there is a rule that pairs each input with exactly one output.

D. An output is a set of ordered pairs in which no y-value repeats.

A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name draw
Tanzania [10]

Answer:

90

Step-by-step explanation:

A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?

This is calculated using the Permutation formula

nPr = n!/(n - r)!

Where:

n = 10 people

r = 2 = 2 positions to be filled , Chairman and Vice chairman

Hence:

10P2 = 10!/(10 - 2)!

= 90 ways
