On a test that has a normal distribution, a score of 28 falls two standard deviations above the mean, and a score of 22 falls one standard deviation below the mean. Determine the mean of this test. PLEASE ITS DUE IN 20 minutes

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
