Answer:
Sample size is 6, event of rolling an even number is 3/6 (or 1/2)
Step-by-step explanation: When you roll a dice it could be 1, 2, 3, 4, 5, or 6. Count those up and you'll have the sample size. Odds of rolling a 2, 4, or 6 (even number) is 3/6 or 1/2, or 50%

Answer:
Na2O + 2HCl -> 2NaCl + H2O then it wil be 10.3 atoms left in the cycle
Step-by-step explanation: you would take
(Na2O) then (HCl) then (NaCl) and, (H2O)
And you would got to the table of atoms and put them together if you look at the name of a chemical it show a number well you would divide them in to fractions and the denominator you would need to focus on because that is going to be your answer.
Answer:
Answer in Explanation
Step-by-step explanation:
His reasoning is wrong. We can evaluate the validity of his reasoning by looking at the basics of what a polynomial is.
In the real sense of it, what makes a polynomial a polynomial is the power to which the variable is raised and not the integer attached to the variable.
In this case, we do not even have an integer attached.
What makes a polynomial a polynomial is that the variable is raised to an exponent or power which is a positive whole number ( integer)
In this case, while x^2 is a polynomial, x^-2 is not and also x^1/2 is not
Only x^2 is qualified as a polynomial because it is the only expression having its powers in positive integers
Hence; 0.5x^2 is a polynomial since it is raised to a positive whole number (integer)
