Theoretical: desired outcomes/total possible outcomes

the same as it was his first time picking before since the prevous results have no bearing on what this trial will yeild
if he didn't replace the marbles then it would be differnt



experimintal=number of event occurnces/total number of trials
so 4/4 or 100% is experimental
so

equal number of red and black and white
1/3 of the bag is black
therefor the probablity of picking a black marble is 1/3
A. 1/3 is theoretical, 4/4=experimental

Answer:

Hey there!

<u>What we know:</u>

  • The three triangles (two smaller ones and one larger one, are all right triangles)
  • Measure of angle A is 42 degrees.
  • Measure of angle C is 58 degrees.
  • AC is 65 m.

<u>What we would like to know:</u>

  • AB
  • BD

First, let's find AB.

Sine 58= AB/65

Solving for AB, we see that it is about 55.12 m.

Next, let's find BD.

Sine 42= BD/55.12

Solving for BD, we see that it is about 36.88 m.

Let me know if this helps :)
