Add 4x²y,-2xy²,-5xy²,3x²y plz explain​

Mathematics
1 answer:
Vinil7 [7]3 years ago
3 0
4x^2 - 2xy^2
5xy^2 +
3x^2y
_____________
12x^5y^4-2xy^2

This is so because 4+5+3 is 12, then using laws of indices to add your x and y you get x^5 and y^4

To simplify your answer to the lowest you have it in the form of
3x^2y^2(4x^2y - 2xy^2)

If you multiply this as well you get the same answer I got with the addition

A random sample of 56 lithium batteries has a mean life of 645 hours with a population standard deviation of 31 hours. Compute t
bearhunter [10]

Answer: A. ​(636.9, 653.1)

Step-by-step explanation:

Given : Sample size : n=56

Significance level :\alpha: 1-0.95=0.05

Critical value :z_{0.05}=1.96

Sample mean : \overline{x}=645\text{ hours}

Standard deviation : \sigma= 31\text{ hours}

The 95% confidence interval for population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=645\pm (1.96)\dfrac{31}{\sqrt{56}}\\\\=645\pm8.1\\\\=(636.9, 653.1)

Hence,  95% confidence interval for population mean is (636.9, 653.1).

19. Luggage on a certain airline is limited to 2 pieces per person.
Mama L [17]

Answer: The second piece can weigh 256 pounds at most.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality with the information given:

The sum of the weight of each piece of Luggage must be less or equal to 581 pounds:

x + 325 ≤581

Where x is the second piece's weight.

Solving for x:

x ≤581 -325

x ≤ 256

The second piece can weigh 256 pounds at most.

Feel free to ask for more if needed or if you did not understand something.
