A furniture factory makes a 4-piece desk. Quality control at the factory has randomly sampled numerous desk sets and determined the number of damaged pieces in each set.
The table below is a partially completed probability distribution for the random variable X, where X represents
the number of damaged pieces in a randomly selected desk set from this factory.

What is the probability that a randomly selected desk set contains exactly 4 damaged pieces?

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.

wait nvm i know the correct answer now its 100%   81 square feet

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
