Answer:

$198

Step-by-step explanation:

To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!

How does claiming more allowances on a W-4 form affect the deductions on a paycheck?

kow [346]

<span>The way how claiming more allowances on a W-4 form affect the deductions on a paycheck is shown in the second option: less will be deducted for taxes. The W-4 form is meant to tell the employer the actual amount of tax to withhold from a paycheck. There is an unwritten law of this system: the more allowances you claim, the less tax will be withheld from each paycheck. And the same happens with fewer allowances- the larger withholding amount, which can lead to a refund.</span>

For the following normal distribution, give the x-values of the inflection points of the curve (the points where the curve's con

3241004551 [841]

Answer:

The x-values of the inflection points of the curve are x = -52 and x = 52.

Step-by-step explanation:

Suppose we have a normal curve with mean $\mu$ and standard deviation $\sigma$

The x-values of the inflection points of the curve are $x = \mu - \sigma$ and $x = \mu + \sigma$

x ~ N(0, 52)

This means that $\mu = 0, \sigma = 52$

$x = 0 - 52 = -52$

$x = 0 + 52 = 52$

The x-values of the inflection points of the curve are x = -52 and x = 52.

A polynomial function of degree 4 with real coefficients could have -3, 1+i, 1-i, and -3,7i as its zeros. true or false

Novosadov [1.4K]

Using complex numbers concepts, it is found that the statement is false.

When a complex number is a root of a polynomial function, it's conjugate also has to be.

A complex number has the format $a + bi$ , and it's conjugate is $a - bi$ .

In this problem:

Real root -3.
Complex-conjugate roots 1 + i and 1 - i.
Complex root -3 + 7i.

The conjugate of -3 + 7i also has to be a root, which would make the polynomial of the 5th degree, as it would have 5 roots, thus, the statement is false.
