Answer:

$66 { \sqrt[\pi \beta \sec( \infty \beta \infty log(e \binom{ \gamma \\ \\ \beta }{?} ) ) ]{?} }^{?}$

Answer 2

Answer: a. 5 answerws

b. 75 points

Step-by-step explanation:

a. The team from St. Joseph School answered 15 questions

correctly. Thus they collected 150 points. However, they did not answered some answers corrrectly and their points left 125. It means that they were punished with 150-125=25 points.  5 points are deducted for

every wrong answer, so 25 /5 = 5

b. 10*10-5*5 = 75
