<span>Question 2.2. Which ordered pairs make the inequality true?</span><span>2x + y > –4</span>The solutions are (-1, 2) and (1, -5), look at the graph in the attachment.

Question 3.3. What is the slope of the line represented by the equation?

There is no equation

Question 4.4. What is the slope of the line represented by the equation 6x - 3y = 4?

Convert to slope-intercept form:

6x - 3y = 4

Subtract 6x to both sides:

-3y = -6x + 4

Divide -3 to both sides:

y = -6/-3x + 4/-3

Simplify:

y = 2x - 4/3

Now it's in slope intercept form, y = mx + b, where 'm' is the slope. So the slope here is 2.

Question 5.5. What is the simplified form of the expression?

15y - 3(4y + 10)

Distribute -3 into the parenthesis:

15y - 12y - 30

Combine like terms:

3y - 30

A university is applying classification methods in order to identify alumni who may be interested in donating money. The univers
HACTEHA [7]

The accuracy in the research done by university is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

Given sample size of 58205 and proportion of people donated 576. Cutoff is 0.5.

Probability is the chance of happening an event among all the events possible. It lies between 0 and 1.

TP=total people donated in sample, TN=total number of people,FP=donation,FN=No donation

Accuracy is calculated as under:

=(TP+TN)/(TP+TN+FP+FN)

=(268+23439)/(238+23439+5375+20)

=23707/29102

=0.81

Accuracy=0.81

Sensitivity is calculated as under:

=TP/(TP+FN)

=268/(268+20)

=268/288

=0.93

Precision is calculated as under:

=TP/(TP+FP)

=268/(268+5375)

=268/5643

=0.047

Their values are the probabilities in itself.

Hence accuracy is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

Find the greatest common factor of the terms in the following expression: 6ab + 18a. 6a, 3a, 2a, a
Oxana [17]

Answer:

6a

Step-by-step explanation:

You can always choose the largest of the offered answers and see if that fits.

6ab +18a = 6a(b +3)

_____

Your general approach to a problem like this is to ...

  • look at what you have
  • identify the factors of each term
  • note which ones are common
  • find the largest common factor of any integer coefficients (It helps to know your times tables.)

Obviously, the only variable factor in the second term is "a". Since that is also a factor in the first term, that is part of the answer.

The constant 6 in the first term is also a factor of 18 in the second term, so it, too, will be part of the answer.

Then, the answer is 6a.
