Answer:
28/155
Step-by-step explanation:
To find people who do use the waterslide and/or the sauna subracter 43 from 155 to get 112.
To find the people who only use the sauna subtract 97 from 112 to get 15.
To find people who use both the waterslide and the sauna subtract 15 from 43 to get 28.
The probability of a person who uses both the waterslide and the sauna is 28/155.
Answer:
720.
Step-by-step explanation:
1*2*3*4 * 5*6
= 24 * 30
= 720.
Splitting it up in this way makes it easier.

Step-by-step explanation:
We have to prove that the diagonals bisect each other in a parallelogram ABCD.
∠ABE≃∠CDE ( by alternate interior angles )
∠DEC≃∠BAE ( alternate interior angles )
∠ABE≃∠CDE by ASA
⇒{AE=CEBE=CE} coordinate sides of ≅ triangle
∠CED≅∠BEA [ vertical angles ]
△AEB≅△DEC [ by SAS≅A′s ]
∠CDE≅∠BAE [ coordinate angles of ≅ triangles. ]
∴AB∥CD by alternate interior angles ≅ of parallel lines.
∠AEC≅∠DEB ( vertical angles )
△AEC≅△DEB ( by SAS )
∠CAE≅∠BDE [ coordinate angle ]
∴AC∥BC by alternate interior angles
Theorm :
A quadrilateral is a parallelogram if and only if the diagonals bisect each other.
Hence, the answer proved.
