Answer:

Answer C

Explanation:

If one of the variables is measured on dichotomous nominal scale, such as gender and other is measured on interval or ratio scale, than we use point biserial correlation coefficient. It will measure our initial hypothesis that there is a connection between the time spent on the phone, talking to your mother with gender. Later, if we would want to conclude how strong is this connection, we would use regression analysis.

Mila [183]

Answer:

b. $2,720,000

Explanation:

The contribution margin is what is left after subtracting the variable cost from the sales.

From there, the company pays their fixed cost and the rest is net income.

In this case you have a company desiring to get 720,000 net income after paying their 2,000,000 fixed cost

So we come up with with formula:

Contribution Margin - Fixed Cost = Net Income

Replacing the know values, we get the unknow value. Like it was a solve for X question:

X - 2,000,000 = 720,000\\X = 2,000,000 + 720,000\\X = 2,720,000

The exchange of information among dns servers regarding configured zones is known as <u>"zone transfer".</u>


DNS zone transfer,  is a kind of DNS transaction. It is one of the numerous instruments accessible for managers to duplicate DNS databases over an arrangement of DNS servers.  

A zone transfer utilizes the Transmission Control Protocol (TCP) for transport, and appears as a client– server exchange. The customer asking for a zone exchange might be a slave server or optional server, asking for information from an ace server, in some cases called an essential server. The part of the database that is duplicated is a zone.

jok3333 [9.3K]

Answer:

The correct answer is : Yes, the offer was revoked by Katherine.

Explanation:

Even if Paul replied Katherine with the acceptance to the first offer, he used a different means of communication to do that -<em>e-mail v. mail</em>. In addition, Katherine sent the revoke by mail -<em>as in the initial offer</em>- before Paul sent his e-mail. So, there is enough proof on Katherine's end that she didn't want to proceed with the offer before Paul confirmed his agreement on the terms. In that sense, Katherine did revoke the initial order.
