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

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
