In a particular roulette game, there's a 1/36 chance of winning. In a single day, a gambler plays 100 rounds and wins in 7 of them. You think the gambler may
be cheating. If you were to test this theory, what would be an acceptable null
hypothesis?
A. If the gambler is cheating, he'd win more than 1 out of every 36 rounds.
B. The P-value is .0217.
C. He's cheating, as evidenced by the P-value.
D. Everyone wins at their own game.
E. The gambler wins about 1 out of every 36 rounds; the wins are due to chance alone.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
