The 3rd option is correct....................
Answer:
- A: z + 1
- B: 6 + W
- D: 2x ^ 4 - y
Step-by-step explanation:
Any expression with terms that have non-negative integer powers of the variables is a polynomial. The cube root of y is not an integer power, so that expression is not part of a polynomial.
The polynomials are listed above.
Answer:
204,160,000
Step-by-step explanation:
Assuming the sample is a good representation of the people from the United States.
Since there were 1,000 surveyed... and 638 of them were wearing glasses, that makes a proportion of 638 out of 1,000 people, or 63,8 / 100 people... so 63.8%... or 0.638
So, if we assume that the US population is of 320 million, how many people does that make wearing glasses.... we just have to multiply 320M by 0.638
G = 320,000,000 * 0.638 = 204,160,000
1/6.
Divide both the numerator and denominator by the greatest common factor (6). 6/6 = 1. 36/6 = 6. So it'd be 1/6.
Hope that helps!
