Which of the following correctly completes the square for the equation below? x^2-9x=0

1 answer:

8 0

The answer to this question is choice B. To complete the square, we take the coefficient on the x term, halve it, and then square it. This results in -9/2, and then 81/4. This value of 81/4 is added to both sides, allowing for factorization of the lefthand side of the equation.

emmainna [20.7K]

Answer:

0.037

Step-by-step explanation:

If the hitter makes an out 72% of the time, then the probabilty that he makes hit in 1 at-bat is $p=0.72$ and the probabilty that he doesn't make hit in 1 at-bat is $q=1-p=1-0.72=0.28.$
