Answer:  Take the information given in the situation. Consider the relationships between the amounts, numbers and unknowns that are in the description.

If the word "is" or "are" is included in the description, that is equivalent to an equal sign.

Words like "and," "also" "more than" and "combined" are clues that there may be addition. "Total" often means the sum of an addition equation.  

"From" and "difference" are clues that there is subtraction.

"Times" "by" and "of" art clues for multiplication. "Find the Area of. . ." dedinitely requires multiplication.

"Ratio," 'into' "per" and "among" are clues to division.

Use a letter x, y, d, t, or whatever helps identify the

Step-by-step explanation: Without a specific situation, it is impossible to give a specific answer.

Examples:  The total number of seats in the auditorium <em>is</em> 125. 75 tickets have been sold already. How many<em> more</em> tickets are left. (This is the unknown)

The Total <em>is  </em>the given 75 plus the unknown.

125 = 75 + x   is the equation to start with

What is three-fourths <em>of </em> twelve?  "What" is the unknown.

x = 3/4 × 12  is the  equation to start with.

The <em>ratio</em> of red marbles to blue marbles is 2:3  There <em>are</em> 25 marbles all together. How many red marbles and how many blue marbles.

In this question there are two equations

2r + 3b = 25 This is the equation for the total    r = 2b/3 is the division

Substitute the value of "r" from the second equation to solve the first equation

2(2b/3) + 3b = 25

If the correlation coefficient in an ordinary least squares regression = 1.00, then A. all the data points must fall exactly on
Hatshy [7]

Answer: Option A is correct.

Step-by-step explanation:

  • The correlation coefficient(r) is a statistical measure that computes the strength of the relationship between two variables.

It lies between -1 and 1.

If the correlation coefficient in an ordinary least squares regression = 1.00.

That indicates that there is a perfect relationship between the variables.

i.e. all the data points must fall exactly on a straight line with a positive slope. .

[when r is positive, the slope of the line is positive].

i.e. option A is correct.

PLZ dont ignore me! I need help on this :(

Answer: It’s the second one!

Explanation: The dot is open and pointing to the side of the numbers greater than -3. It has to be an open dot because it is “greater than -3” not “greater than or equal to-3”! :)
