Isla flipped a coin 30 times. the coin landed heads up 9 times and tails up 21 times. part a: based on the results, what is the experimental probability of the coin landing heads up? show your work. (5 points) part b: what is the theoretical probability of the coin landing heads up? show your work. (5 points)

A.) Either way the probability would be 1/2 because there are only 2 sides of a coin so fate decides on which side it will land on.

B.)Same as A

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
