The answer is 75 . because you have to divide 45 by 3 to get the starter total which was 15 and then multiple 15 by 5 which give you 75 . therefore anna can buy 5 sweatshirts for $75 .
44= 32 + 4h
44-32 = 4h
12 = 4h
h = 12/4
h = 3
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.

Step-by-step explanation:
Yes, the degree of the of the polynomial will tell how much roots it has.
A linear equation with degree has one root so it only has 1 possible answer.
A quadratic equation with the degree of 2 has two possible roots.
So write a polynomial equationcwith the highest degree of 9.
