Acomputer is programmed to make 100 draws at random with replacement from the box , and take their sum. it does this 144 times; the average of the 144 sums is 21.13. the program is working fine. or is it?
a. working fine
b. something is wrong
choose one option, and explain your reason

Did you get there answer to 44?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

If i'm correct the answer is $15.97
