Standard form of Polynomials is given below .
Step-by-step explanation:
1. A polynomial is in standard form when its term of highest degree is first, its term of 2nd highest is 2nd etc.
Correct, standard form means that the terms are ordered from biggest exponent to lowest exponent. The leading coefficient is the coefficient of the first term in a polynomial in standard form. For example, 3x^4 + x^3 - 2x^2 + 7x.
2. Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer. For example, 3x+2x-5 is a polynomial.
3.Polynomials with more than 3 terms can be called simply polynomials. They're all polynomials. Otherwise, you can use the appropriate prefix (i.e. quadrinomial = polynomial with 4 terms).
As for monomials being considered polynomials, monomials are just a special case of polynomials in which there is only one term. Polynomials can be long strings of terms, or in other words, monomials.
3.125 + (-3.9) - (2.46)
= 3.125 -3.9 -2.46
= -0.775 -2.46
= -3.235
Answer:
The confidence interval for the difference in proportions is
No. As the 95% CI include both negative and positive values, no proportion is significantly different from the other to conclude there is a difference between them.
Step-by-step explanation:
We have to construct a confidence interval for the difference of proportions.
The difference in the sample proportions is:
The estimated standard error is:
The z-value for a 95% confidence interval is z=1.96.
Then, the lower and upper bounds are:
The confidence interval for the difference in proportions is
<em>Can it be concluded that there is a difference in the proportion of drivers who wear a seat belt at all times based on age group?</em>
No. It can not be concluded that there is a difference in the proportion of drivers who wear a seat belt at all times based on age group, as the confidence interval include both positive and negative values.
This means that we are not confident that the actual difference of proportions is positive or negative. No proportion is significantly different from the other to conclude there is a difference.
