An art supply store sells posters for $9 each and pictire frames for $15 each
77julia77 [94]
Since posters cost 9 dollars each and picture frames cost 15, it would be multiplication.

The expression would be 9(6)+15(6) or 9x6+15x6.

You have to multiply these numbers. 9 times 6 would be 54. 15 times 6 would be 90.

Now, we need to add these together. 54 plus 90 would be 144.

The total cost for 6 framed posters would be $144.

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.

Form a union for the following sets. K = {2, 3, 5, 8} L = {3, 5, 7}
Kisachek [45]
A union for sets means you combine the two sets together. The symbol of a union is ∪, so we can represent this question with K <span>∪ L.

You simply must combine the two sets together without repeating any of the same numbers.

K </span><span>∪ L = {2, 3, 5, 7, 8}.</span>
