zheka24 [161]

Answer:

Anne is the best hitter as she has the best hitting average of 0.406

Step-by-step explanation:

Anne hits 65 bases out of 160 at - bats.

Beth's betting average = 0.399

Collin's hit = 40%

Now, we need to convert all the three hitting rates into same parameters to compare them with each other.

Average hit rate of Anne = \frac{\textrm{Total numberof base}}{\textrm{Total number of  at - bats}}

= \frac{65}{160}  = 0.406

⇒The betting average of Anne = 0.406

Now, The hit - rate of Collin = 40%

Converting the percentage rate into decimal, we get the hit rate of Collin

= \frac{40}{100}  = 0.40

Hence, we get that Hitting Average of :

<u>Anne = 0.406</u>,  Beth = 0.3999 and Collin = 0.400

Hence, from the above data Anne is the best hitter as she has the best hitting average of 0.406.

Marianna [84]

9514 1404 393

Answer:

  110 units

Step-by-step explanation:

Fill in the given value and solve for x.

  c = x^2 -10x +35

  11035 = x^2 -10x +35

  11025 = x^2 -10x +25 = (x -5)^2 . . . . subtract 10 to complete the square

  x = 5 +√11025 = 5 +105 . . . . find the positive solution

  x = 110

The number of units manufactured at a cost of 11,035 is 110 units.
