pedro has scores of 88,80.83 and 74 after four tests. what score must he make on his fifth test to have an average of 76 or grea
daser333 [38]

We start to solve this by looking for the formula that let us calculate an average value, this formula would be:

save=\frac{1+s2+s3+s4+s5}{5}

where Save is the average score and s is the score of each exam, Since we know the value of the score Save and 4 of the exams we can replace them in the formula, like this:

And we can solve for s5, which is the score that we need to find, like this:

\begin{gathered} 74\times5=\frac{88+80+83+74+s5}{5}\times5 \\ 74\times5=88+80+83+s5 \\ 74\times5-88-80-83-74=88+80+83+74-88-80-83-74+s5 \\ 74\times5-88-80-83-74=s5 \\ s5=74\times5-88-80-83-74=55 \end{gathered}

Then, Pedro must have a 55 score on the fifth test

Given f(x)=x2−2x−2, completing the square to solve for the function's zeros yields which of the following? A. (x−1)2=−2 B. (x−2)
LekaFEV [45]

Answer:

(x-1)² = 3

Step-by-step explanation:

Given f(x)=x²−2x−2

Completing x²−2x−2 = 0 to square

  • x²−2x − 2=0
  • x²−2x + 1 - 3 =0
  • (x - 1)² - 3 = 0
  • (x - 1)² = 3

Correct choice is D
