Answer:
17
Step-by-step explanation:
Add up the values (13, 22, 15, 15, 14) and subtract from the product of 16 and 6
Answer:
17
Step-by-step explanation:
the mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be the age of the person entering the room, then sum of 6 is
sum = 13 + 22 + 15 + 14 + 15 + x = 79 + x
[tex]\frac{79+x}{6}[/tex] = 16 ( multiply both sides by 6 to clear the fraction )
79 + x = 96 ( subtract 79 from both sides )
x = 17
the age of the person who entered the room is 17
