Answer:
0.004 :) you can get these calculations on google, by the way
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.

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.
