A basketball player has made 21 of her last 30 free throws a percentage of 70, how can you model the player's free throw percent
marysya [2.9K]

<span>For this case what you should do is write the following function:</span>

<span> y = (a / b) * 100</span>

<span> Where,</span>

<span> A: amount of successful free throws</span>

<span> B: total amount of free throws</span>

<span> Substituting values we have:</span>

<span><span> y  = (21/30) * 100</span></span>

<span><span> The result is:</span></span>

<span><span> Y = 70% (as we expected)</span></span>

Answer:

  a.  plane DEA

Step-by-step explanation:

A plane can be named by naming any 3 non-collinear points in the plane, or by using the plane's name as indicated in the drawing.

Here, points in the plane are A, D, E, F, with DEF all on  the same line. So A plus any two points from the line will constitute a name for the plane. Also, this plane is identified with a script M that can be used to name the plane.

M is not an answer choice, but DEA is. So, the appropriate choice is ...

  plane DEA

__

F is a point, not a plane name. C is not on the plane, so cannot be used to name it. 'k' is a line name, not a plane name.
