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.

Input in stand form the equation of the given line.
Daniel [21]

Answer:

  3x +8y = -17

Step-by-step explanation:

The point-slope equation is a good place to start.

  y -k = m(x -h) . . . . . equation through (h, k) with slope m

Filling in your numbers gives ...

  y +4 = -3/8(x -5)

Multiplying by 8, we get

  8y + 32 = -3x + 15

Adding 3x-32 puts this in standard form.

  3x + 8y = -17

_____

Standard form is ...

  ax +by = c

where a, b, c are mutually-prime integers and the leading coefficient is positive. (If a=0, the leading coefficient is b.)
