Astandard deck of 52 cards contains four suits: clubs, spades, hearts, and diamonds. each deck contains an equal number of cards in each suit. rochelle chooses a card from the deck, records the suit, and replaces the card. her results are shown in the table. cards suit observed frequency clubs 29 spades 13 hearts 15 diamonds 23 how does the experimental probability of choosing a heart compare with the theoretical probability of choosing a heart?

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.

it would open into a square depending on the type of envelope i’m not sure about the second part
