Answer:
42
Step-by-step explanation:
let's make the missing number x
[tex]mean = \frac{sum \: of \: numbers}{how \: many \: numbers \: there \: are} [/tex]
[tex]41 = \frac{48 + 33 + x}{3} [/tex]
multiply 3 on both sides to get rid of the fraction, 41 × 3 = 123
[tex]123 = 48 + 33 + x[/tex]
simplify the right side, 48 + 33 = 81
[tex]123 = 81 + x[/tex]
subtract 81 on both sides
[tex]123 - 81 = x[/tex]
[tex]x = 42[/tex]
