The result is 1.08 m. because applying the Pythagorean theorem will yield it.
2.8^2+b^2=3^2
7.84+b^2=9
b^2=9-7.84
taking the square root of b^2 gives the square root of 1.16
b=1.08
The average score amounts to 73. Your average score is calculated by summing each test score, adjusted by the weight assigned to each test. The data we have includes: a score of 90 on the midterm, weighted at 30%; a score of 60 on the final, weighted at 50%; and a score of 80 on the class project, which is worth 20%. The average score is determined as follows: A = 90*0.3 + 60*0.5 + 80*0.2 = 73.
C because a negative would turn into a positive.
