Scores on the sat college entrance test in a recent year were roughly normal with mean 1026 and standard deviation 209. you choose an srs of 100 students and find their average sat score, x-bar. if you repeatedly take srs of 100 students and calculate x-bar for each sample, then the mean of the sampling distribution you create will be closest to

y=mx+

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.
