The distribution of SAT scores of all college-bound seniors taking the SAT in 2014 was approximately normal with mean 1497 and standard deviation 322. A certain test-retake preparation course is designed for students whose SAT scores are in the lower 25% of those who take the test in a given year. What is the maximum SAT score in 2014 that meets the course requirements?

1 Name three ways residents of Norman County contributed to the war effort. (World War I)

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
