Kaylis [27]

Correct Answers only please!
Allushta [10]

Answer:

  C.  20, 40, 4, 56

Step-by-step explanation:

In order for the slugging percentage to be more than 0.500, the number of bases must exceed 200 for 400 At Bats. Clearly, the option with 56 homers will do that, since the homers alone account for 224 bases.

The set of choice C would have a slugging percentage greater than 0.500.

Find the distance between the points (5, -5) and (-7,4).
abruzzese [7]

Answer:

<h2>The answer is 15 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5, -5) and (-7,4)

The distance between them is

d =  \sqrt{ ({5 + 7})^{2}  +  ({ - 5 - 4})^{2} }  \\  =  \sqrt{ {12}^{2}  + ( { - 9})^{2} }  \\  =  \sqrt{144 + 81}  \\  =  \sqrt{225}  \\  = 15 \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>15 units</h3>

Hope this helps you
