If the mathematics scores of the SAT college entrance exams are normal with mean 480 and standard deviation 80, and if some college sets 520 as the minimum score for new students, what percent of students would not reach that score?

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

add them

step-by-step explanation:

idk you did not give the options or numbers so you cant solve it
