Which is true about the polynomial –3xy2 + 5x2y?

Semmy [17]

Answer: The answer is a cubic binomial.

Step-by-step explanation: The given polynomial is

$P(x,y) =-3xy^2+5x^2y.$

We are to write the truth about the above polynomial, its type, etc.

Since the polynomial contains two expressions (terms), so it is a binomial.

Also, the degree of both the terms $-3xy^2$ and $5x^2y$ is 3.

We know that the degree of a polynomial is the highest degree among the terms that are present in the polynomial, so the degree of P(x, y) is 3.

Therefore, P(x, y) is a binomial of degree 3.

Thus, it is a cubic binomial.

Tanzania [10]

Answer:

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

560 random tests conducted, 26 employees failed the test. This means that $n = 560, \pi = \frac{26}{560} = 0.046$

98% confidence level

So $\alpha = 0.02$ , z is the value of Z that has a pvalue of $1 - \frac{0.02}{2} = 0.99$ , so $Z = 2.33$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 - 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.025$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 + 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.067$

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).

Need help with calculus asap with steps

Tasya [4]

Answer:

p=7/2

Step-by-step explanation:

Rember that a p series can be represented by

$\frac{1}{k {}^{p} }$

Here, notice that

$\frac{1}{8 \sqrt{2} } = \frac{1}{2 {}^{3} \sqrt{2} } = \frac{1}{2 {}^{3} \times 2 {}^{ \frac{1}{2} } } = \frac{1}{2 {}^{ \frac{7}{2} } }$

This is true for all parts of the series because

$27 \sqrt{3} = 3 {}^{ \frac{7}{2} }$

So p=7/2
