Question

for the given date 11, 15, 17, Y + 1, 19, Y - 2, 3 if the mean is 14 find the value of Y​

Answer 1

Answer: Y = 17

Step-by-step explanation:

Mean = 14

Mean = Sum/Number

Sum = 11+15+17+(Y+1)+19+(Y-2)+3 = 2Y + 64

Number = 7

14 = (2Y+64)/7

14*7 = 2Y + 64

98 = 2Y + 64

2Y = 98-64 = 34

Y = 34/2 = 17
